holding the piston rod with an 8 mm Allen key. If the adaptor needed to do this is not available, the nut can be tightened initially with a ring spanner while the piston rod is held. Final tightening can then be carried out using a torque wrench and a conventional socket (see illustration). Warning: Before attempting to dismantle the front suspension strut, a tool to hold the coil spring in compression must be obtained. Do not attempt to use makeshift methods. Uncontrolled release of the spring could cause damage and personal injury. Use a high-quality spring compressor, and carefully follow the tool manufacturer’s instructions provided with it. After removing the coil spring with the compressor still fitted, place it in a safe, isolated area. 1If the front suspension struts exhibit signs of wear (leaking fluid, loss of damping capability, sagging or cracked coil springs) then they should be dismantled and overhauled as necessary. The struts themselves cannot be serviced, and should be renewed if faulty, but the springs and related components can be renewed. To maintain balanced characteristics on both sides of the vehicle, the components on both sides should be renewed at the same time. 2With the strut removed from the vehicle, cleanaway all external dirt, then mount it in a vice. 3Fit the coil spring compressor tools (ensuring that they are fully engaged), and compress the spring until all tension is relieved from the upper mounting (see illustration). 4Hold the strut piston with an Allen key, andunscrew the thrust bearing retaining nut with a ring spanner (see illustration). 5Withdraw the top mounting, thrust bearing, upper spring seat and spring, followed by the gaiter and the bump stop (see illustrations). 6If a new spring is to be fitted, the original 5 Front suspension strut - overhaul Suspension and steering systems 10•7 10 5.5A Front suspension strut components 1 Cap 2 Nut 3 Retainer 4 Nut 5 Top mounting 6 Thrust bearing7 Upper spring seat 8 Spring 9 Bump stop 10 Gaiter 11 Lower spring seat12 Strut 13 Steering knuckle 14 Clamp bolt 15 Solenoid valve for models with adaptive damping 4.24 Final tightening of the front suspension strut upper mounting nut5.3 Coil spring compressor tools fitted to the coil spring5.4 Unscrewing the nut from the top of the strut 5.5B Removing the top mounting from the strut5.5C Removing the gaiter5.5D Removing the bump stop
spring must now be carefully released from the compressor. If it is to be re-used, the spring can be left in compression. 7With the strut assembly now completely dismantled, examine all the components for wear and damage, and check the bearing for smoothness of operation. Renew components as necessary. 8Examine the strut for signs of fluid leakage. Check the strut piston for signs of pitting along its entire length, and check the strut body for signs of damage. Test the operation of the strut, while holding it in an upright position, by moving the piston through a full stroke, and then through short strokes of 50 to 100 mm. In both cases, the resistance felt should be smooth and continuous. If the resistance is jerky, uneven, or if there is any visible sign of wear or damage to the strut, renewal is necessary. 9Reassembly is a reversal of dismantling, noting the following points: (a) Make sure that the coil spring ends are correctly located in the upper and lower seats before releasing the compressor. (b) Check that the bearing is correctly fitted to the piston rod seat. (c) Tighten the thrust bearing retaining nut to the specified torque. Removal 1Apply the handbrake, jack up the front of the vehicle and support it on axle stands. Remove both front wheels. 2Unscrew the nuts, and disconnect the anti- roll bar links from the front suspension struts on both sides of the vehicle. Note that, on models with ABS, the wheel sensor wiring support brackets are located beneath the nuts (see illustrations). 3Unscrew and remove the anti-roll bar mounting bolts from the engine subframe on both sides of the vehicle. 4Withdraw the anti-roll bar from one side of the vehicle, taking care not to damage the surrounding components.5If necessary, unscrew the nuts and remove the links from the anti-roll bar. Refitting 6Refitting is a reversal of the removal procedure. Removal 1Apply the handbrake, jack up the front of the vehicle and support it on axle stands. Remove the appropriate wheel. 2If removing the right-hand side lower arm, remove the auxiliary drivebelt cover where necessary. 3Unscrew and remove the nuts and bolts securing the lower arm to the subframe (see illustration). 4Unscrew the nuts and disconnect the anti- roll bar links from the anti-roll bar on both sides. Swivel the anti-roll bar upwards away from the lower arm. 5Extract the split pin from the track rod end balljoint nut. Unscrew the nut, and detach the rod from the arm on the steering knuckle using a conventional balljoint removal tool. Take care not to damage the balljoint seal. 6Remove the clip securing the driveshaft inner gaiter to the inner CV joint, and disconnect the gaiter from the CV joint housing. This is necessary to prevent damageto the gaiter when the steering knuckle is moved outwards to remove the lower arm. 7Note which way round the front suspension lower arm balljoint clamp bolt is fitted, then unscrew and remove it from the knuckle assembly. Lever the balljoint down from the knuckle; if it is tight, prise the joint open carefully using a large flat-bladed tool. Take care not to damage the balljoint seal during the separation procedure. Support the inner end of the driveshaft on an axle stand (see illustrations). 8Remove the lower arm from the subframe, and withdraw it from the vehicle. Overhaul 9Examine the rubber bushes and the suspension lower balljoint for wear and damage. The balljoint may be renewed as described in Section 8. The rubber bushes may be removed using a press, or a length of metal tubing together with a long bolt, washers and nut. 10Note that the front and rear bushes are different. The front one has a solid rubber bush with a cylindrical inner tube, whereas the rear one has a voided rubber bush with a barrel-shaped inner tube (see illustration). 11Press the new bushes into the lower arm, using the same method as used for removal. Note that, when fitting the rear bush, the voids must be in line with the front bush location. On later models, a pip on the rear bush must be aligned with a triangular alignment mark on the arm. 7 Front suspension lower arm - removal, overhaul and refitting 6 Front anti-roll bar and links - removal and refitting 10•8 Suspension and steering systems 6.2A Unscrew the nut . . .6.2B . . . and disconnect the anti-roll bar link and (on ABS models) the sensor wiring support bracket 7.3 One of the nuts and bolts securing the lower arm to the subframe7.7A Unscrew the lower arm balljoint clamp bolt . . .7.7B . . . and disconnect the balljoint from the knuckle
Refitting 12Locate the lower arm on the subframe, and insert the mounting bolts. Fit the nuts and tighten them in stages, first to the specified torque and then through the angle specified. 13If removed, locate the tripod on the inner end of the driveshaft in the CV joint housing, then refit the gaiter, together with a new clip. 14Refit the front suspension lower arm balljoint to the knuckle assembly, and insert the clamp bolt with its head facing forwards. Refit the nut and tighten to the specified torque. 15Refit the track rod end balljoint to the steering knuckle, and tighten the nut to the specified torque. Check that the split pin holes are aligned; if necessary, turn the nut to align the holes, making sure that the torque wrench setting is still within the specified range. Insert a new split pin, and bend it back to secure. 16Swivel the anti-roll bar down, then reconnect the links to the bar and tighten the nuts to the specified torque. 17If working on the right-hand side, refit the auxiliary drivebelt cover where necessary. 18Refit the wheel, and lower the vehicle to the ground. Note:If the lower arm balljoint is worn, either the complete lower arm or the balljoint alone can be renewed. If the balljoint has already been renewed, it will be bolted in position; if the original balljoint is being renewed, then it will be riveted in position (see illustration). This Section describes the renewal of a riveted balljoint.1Remove the front suspension lower arm as described in Section 7. It is not recommended that the balljoint be replaced with the lower arm in position on the vehicle; the accurate drilling necessary may not be possible, and the holes in the arm may be enlarged. 2With the lower arm on the bench, use a 3 mm drill to make a pilot hole through each of the three rivets. Now use a 9 mm drill to drill the rivets to a depth of 12 mm, then use a 7 or 8 mm drift to drive the rivets out of the arm. 3Clean any rust or dirt from the rivet holes. 4The new balljoint is supplied with a protective plastic cover over the rubber boot and stub, and it is recommended that this remains in position until it is time to connect the balljoint to the steering knuckle. 5Locate the new balljoint on the lower arm, and use three new bolts to secure it, inserting the bolts from the top of the arm. Tighten the nuts to the specified torque. Make sure that the location lug on the balljoint engages the hole in the lower arm (see illustration). 6Refit the front suspension lower arm as described in Section 7. Note:Removal of the rear hub damages the bearings, and renders them unserviceable for future use. The hub and bearing assembly mustalways be renewed if it is removed. Inspection 1The rear hub bearings are non-adjustable, and are supplied complete with the hub. It is not possible to renew the bearings separately from the hub. 2To check the bearings for excessive wear,chock the front wheels, then jack up the rear of the vehicle and support it on axle stands. Fully release the handbrake. 3Grip the rear wheel at the top and bottom, and attempt to rock it. If excessive movement is noted, or if there is any roughness or vibration felt when the wheel is spun, it is indicative that the hub bearings are worn. Renewal 4Remove the rear wheel. 5On models fitted with rear brake drums, remove the rear brake drum as described in Chapter 9. 6On models fitted with rear brake discs, remove the rear brake disc as described in Chapter 9. 7On all models, tap off the dust cap and unscrew the hub nut. Note that the nut is of special laminated design, and should only be re-used a maximum of 5 times. It is a good idea to mark the nut with a file every time it is removed. Obtain a new one if necessary. 8Using a suitable puller, draw the hub and bearing assembly off the stub axle. Note that this procedure renders the bearings unserviceable for future use. 9Locate the new rear hub and bearing assembly on the stub axle, then refit the hub nut and tighten it to the specified torque. 10Tap the dust cap fully onto the hub. 11Refit the rear brake disc or drum as applicable, as described in Chapter 9. 12Refit the rear wheel, and lower the vehicle to the ground. 9 Rear hub and bearings (Saloon/Hatchback models)- inspection and renewal 8 Front suspension lower arm balljoint - renewal Suspension and steering systems 10•9 10 7.10 Front suspension lower arm bushes 1 Front bush 2 Cylindrical inner tube3 Rear bush 4 Barrel-shaped inner tube5 Front of vehicle 8.5 Location lug (1) and bolt hole (2) in the front suspension lower arm balljoint 8.0 Original riveted front suspension lower arm balljoint
Note:Removal of the rear hub from the knuckle damages the bearings, and renders them unserviceable for future use. The hub and bearing assembly mustalways be renewed if it is removed. Removal 1Chock the front wheels, then jack up the rear of the vehicle and support it on axle stands. Remove the appropriate rear wheel. 2When applicable, remove the ABS sensor from the knuckle as described in Chapter 9. 3Remove the rear hub and bearing assembly as described in Section 9. Drum brake models 4Fit a brake hose clamp to the flexible brake hose, then release the clip and detach the flexible hose from the strut. Unscrew the union nut, and detach the rigid brake pipe from the wheel cylinder. If preferred (to eliminate any bleeding procedure during refitting) the rigid brake pipe may remain attached to the wheel cylinder, provided that care is taken to prevent damage to both the rigid and flexible brake pipes. 5Unbolt the backplate from the rear suspension knuckle (see illustration), and support it to one side on an axle stand. The brake shoes and handbrake cable can remain attached. Disc brake models 6Unbolt the splash shield from the rear suspension knuckle. All models 7Unscrew and remove the bolt securing the tie-bar to the bottom of the knuckle, and move the tie-bar downwards. 8Unscrew and remove the bolts securing the front and rear lower arms to the knuckle, and move the arms to one side. 9Support the knuckle on an axle stand, then unscrew and remove the clamp bolt securing the knuckle to the strut. 10Prise the top of the knuckle apart carefully using a large flat-bladed tool, and withdrawthe knuckle downwards from the strut. Withdraw the knuckle from under the rear wheel arch. Refitting 11Locate the knuckle fully on the strut, then insert the clamp bolt and tighten to the specified torque. 12Refit the front and rear lower arms to the knuckle, and insert the bolts finger-tight at this stage. 13Refit the tie-bar to the bottom of the knuckle, and insert the bolt finger-tight at this stage. 14Refit the backplate (or splash shield, as applicable) to the rear suspension knuckle, and tighten the bolts to the specified torque. Drum brake models 15Reconnect the rigid brake pipe to the wheel cylinder (if disconnected), and tighten the union nut. 16Attach the flexible hose to the strut, refit the clip, and remove the hose clamp. All models 17Fit a new rear hub and bearing assembly as described in Section 9. 18Where applicable, refit the ABS sensor as described in Chapter 9. 19Refit the wheel, and lower the vehicle to the ground. 20With the weight of the vehicle on the suspension, fully tighten the mounting bolts for the tie-bar and lower arms. 21Where applicable, bleed the hydraulic brake circuit as described in Chapter 9. Note:Before attempting to remove the rear suspension strut, a tool to hold the coil spring in compression must be obtained. Careful use of conventional coil spring compressors will prove satisfactory. Removal 1In order to remove the rear suspension strut, the coil spring must be temporarily compressed. This will enable the piston rod tobe retracted into the strut, and will provide additional room for releasing the strut from the bump stop on top of the rear suspension crossmember. Warning: It is important to only use a high-quality spring compressor; carefully follow the tool manufacturer’s instructions provided with it. 2Chock the front wheels, then jack up the rear of the vehicle and support it on axle stands. Remove the appropriate wheel. 3Where fitted, unclip the ABS sensor wiring from the strut, and remove the sensor from the knuckle as described in Chapter 9 (see illustration). 4On models fitted with adaptive damping, unclip the wiring from the strut and disconnect the multi-plug (see illustration). 5On drum brake models, fit a brake hose clamp to the rear flexible brake hose, then unscrew the union nut securing the rigid brake pipe to the flexible hose on the strut. Extract the clip, and disconnect the flexible hose from the strut. 6On models fitted with rear disc brakes, unbolt the caliper from the knuckle as described in Chapter 9, but leave the hydraulic hose attached. Support the caliper on an axle stand, making sure that the flexible hose is not strained. 7Unscrew the nut securing the rear anti-roll bar link to the front lower arm on the appropriate side. Hold the actual link with an adjustable spanner or grips while unscrewing the nut, to prevent damage to the link joint. 8Unscrew and remove the bolt securing the tie-bar to the bottom of the knuckle. Move the tie-bar downwards (see illustrations). 9Unscrew and remove the bolts securing the front and rear lower arms to the knuckle, and move the arms to one side (see illustrations). 10Support the knuckle on a trolley jack, then unscrew and remove the clamp bolt securing the knuckle to the strut (see illustrations). 11Prise the clamp on the knuckle apart using a large flat-bladed tool. Disconnect the knuckle from the strut, and lower it on the trolley jack as far as possible, taking care not to damage the handbrake cable (see illustration). 11 Rear suspension strut (Saloon/Hatchback models) - removal and refitting 10 Rear suspension knuckle (Saloon/Hatchback models)- removal and refitting 10•10 Suspension and steering systems 10.5 Two of the bolts securing the brake backplate to the rear suspension knuckle11.3 Unclipping the ABS sensor wiring from the strut11.4 Location of the adaptive damping lead (1) and multi-plug (2)
12Fit the coil spring compressor tool (ensuring that it is fully engaged), and compress the coil spring until all tension is relieved from the upper and lower mountings (see illustration). This will also release the bracket on the strut from the bump stop rubber on the top of the rear crossmember. 13Support the strut, then reach up under the wheel arch, and unscrew the two bolts securing the upper mounting to the underbody (see illustration). 14Slightly lift the strut, to force the piston into the shock absorber and release the strut bracket from the bump stop on the crossmember. Lower the strut assembly and withdraw it from under the vehicle (see illustration).

Refitting 15Locate the strut assembly (together with the coil spring compressor tool) under the wheel arch, and locate the bracket on the bump stop on the rear suspension crossmember. Insert the two bolts securing the upper mounting to the underbody tower, and tighten them to the specified torque. 16Carefully release the coil spring compressor tool, making sure that the spring locates correctly in the upper and lower seats, and that the strut bracket locates on the crossmember bump stop. The bump stop is tapered inwards, and the strut bracket should be fully engaged with it before releasing the coil spring. 17Raise the knuckle and engage it with the strut, then insert the clamp bolt and tighten to the specified torque. 18Reconnect the front and rear lower armsto the knuckle, and finger-tighten the bolts at this stage. 19Reconnect the tie-bar to the bottom of the knuckle, and finger-tighten the bolt at this stage. 20Refit the anti-roll bar link to the lower arm, and tighten the nut to the specified torque. 21On disc brake models, refit the caliper bracket to the knuckle, and tighten the mounting bolts to the specified torque (see Chapter 9). Make sure that the flexible brake hose is not twisted. 22On drum brake models, connect the flexible hose to the strut, insert the clip, then insert the rigid brake line and tighten the union nut. Remove the brake hose clamp, then bleed the hydraulic brake circuit as described in Chapter 9. 23Where applicable, reconnect the wiring multi-plug for the adaptive damping, and clip the wiring to the strut.24Where applicable, refit the ABS sensor as described in Chapter 9, and clip the wiring to the strut. 25Refit the wheel, and lower the vehicle to the ground. 26With the weight of the vehicle on the rear suspension, fully tighten the lower arm and tie-bar mounting bolts. 1The procedure is similar to that for the front suspension strut, and reference should be made to Section 5. Note that the spring compressor tools will already be in position on the coil spring following the removal operation. Refer also to the accompanying illustrations for details of the separate components (see illustrations). Removal 1Chock the front wheels, then jack up the rear of the vehicle and support it on axle stands. Remove both rear wheels. 2Unscrew the nuts securing the anti-roll bar links to the front lower arms on both sides. Hold the upper part of the links with a spanner while loosening the nuts. Recover the rubber bushes (see illustrations). 13 Rear anti-roll bar and links (Saloon/Hatchback models) - removal and refitting 12 Rear suspension strut (Saloon/Hatchback models)- overhaul 10•12 Suspension and steering systems 12.1A Rear strut dismantling - unscrew the upper mounting nut . . .12.1B . . . remove the cup . . .12.1C . . . upper mounting bracket and seat . . . 13.2A Loosen the nut . . .13.2B . . . remove the nut and rubber bush . . . 12.1D . . . gaiter and bump stop . . .12.1E . . . and coil spring 13.2C . . . and remove the anti-roll bar link from the lower arm
3Unscrew the bolts securing the anti-roll bar mounting clamps to the rear suspension crossmember, then unhook the clamps and withdraw the anti-roll bar from under the vehicle (see illustration). 4Examine the rubber bushes for the mounting clamps and links, and if necessary renew them. The links are available individually. Refitting 5Locate the anti-roll bar on the rear crossmember, hook the mounting clamps in position, and insert the bolts. Tighten the bolts to the specified torque. 6Locate the anti-roll bar links in the front lower arms on both sides, making sure that the rubber bushes are in position. Refit the nuts and tighten them to the specified torque. 7Refit the rear wheels, and lower the vehicle to the ground. Removal 1Chock the front wheels, then jack up the rear of the vehicle and support it on axle stands. Remove the appropriate rear wheel. Front lower arm 2To remove the front lower arm, it is necessary to remove the fuel tank first. Refer to Chapter 4 for details. 3Unscrew the nut and disconnect the anti- roll bar link from the lower arm. Hold the actual link with an adjustable spanner or grips while unscrewing the nut, to prevent damage to the link joint. Recover the rubber bush. 4Unscrew and remove the bolt securing the front lower arm to the knuckle. 5Unscrew and remove the bolt securing the front lower arm to the crossmember. 6Withdraw the front lower arm from under the vehicle. Rear lower arm 7Unscrew and remove the bolt securing the rear lower arm to the knuckle.8The bolt securing the rear lower arm to the crossmember has an eccentric head and spacer, which are used to adjust the rear toe setting. Before removing this bolt, mark its position, using a scriber or similar sharp instrument through the aperture in the crossmember. 9Unscrew and remove the bolt securing the rear lower arm to the crossmember (see illustration). The bolt may be removed through the aperture in the crossmember. Recover the eccentric spacer. 10Withdraw the rear lower arm from under the vehicle. Refitting 11Refitting is a reversal of the removal procedure, but the arm mounting bolts should be finger-tightened initially, and only fully tightened after the vehicle is lowered to the ground, so that its weight is on the rear suspension. Note that the rear lower arm is marked “TOP” for correct refitting (see illustration). The rear toe setting should be checked, and if necessary adjusted, at the earliest opportunity. Removal 1Chock the front wheels, then jack up the rear of the vehicle and support it on axle stands. Remove the appropriate rear wheel. 2Disconnect the handbrake cable from the tie-bar bracket on the underbody. 3Unscrew and remove the bolt securing the tie-bar bracket to the rear suspension knuckle. 4Unscrew the bolts securing the tie-bar bracket to the underbody, and withdraw the bracket from the vehicle (see illustration). 5Mount the bracket in a vice, then unscrew and remove the bolt, and remove the tie-bar from the bracket. 6It is not possible to renew the rubber bushes - if they are worn excessively, the tie- bar should be renewed complete. Refitting 7Refitting is a reversal of the removal procedure. The bracket-to-underbody bolts should be fully tightened to the specified torque before lowering the vehicle. The bolts securing the tie-bar to the bracket and knuckle should be finger-tightened initially, and only fully tightened after the vehicle is lowered to the ground, so that its weight is on the rear suspension. Note:Before attempting to remove the rear suspension crossmember, tools to hold the coil springs in compression must be obtained. Careful use of conventional coil spring compressors will prove satisfactory. Removal 1Chock the front wheels, then jack up the rear of the vehicle and support it on axle stands. Remove both rear wheels. 2Remove the complete exhaust system as described in Chapter 4. 3Unscrew and remove the bolts securing the tie-bars to the rear suspension knuckles, and disconnect the tie-bars. 4Unscrew the nuts securing the rear anti-roll bar links to the front lower arms.

actual links stationary while the nuts are being unscrewed, to prevent damage to the joints. Swivel the anti-roll bar upwards, and recover the rubber bushes. 5Where applicable, remove the ABS wheel sensor from the rear suspension knuckle as described in Chapter 9. 6Unscrew and remove the bolts, and disconnect both lower arms from the rear suspension knuckle. 7To allow the rear suspension struts to be released from the rubber stops on the top of the crossmember, it is necessary to fit coil spring compressor tools to both of the rear coil springs, and compress them until all tension is removed from the upper and lower mountings. Warning: It is important to only use high-quality spring compressors, and to carefully follow the tool manufacturer’s instructions provided with them. With the compressor tools fitted, support the struts to one side. 8Support the rear suspension crossmember on a trolley jack, then unscrew the four mounting bolts from the underbody (see illustration). 9Lower the crossmember to the ground. 10Unscrew the bolts securing the anti-roll bar clamps to the crossmember, then remove the clamps and withdraw the anti-roll bar. 11Remove the lower arms from the crossmember as described in Section 14. Refitting 12Refitting is a reversal of the removal procedure. Ford specify the use of a special tool (tool number 15-097) to accurately align the crossmember onto the underbody before tightening the mounting bolts. This tool should be obtained if possible, since inaccurate alignment would result in bad handling and excessive tyre wear. The tie-bar and arm mounting bolts should be finger- tightened initially, and only fully tightened after the vehicle is lowered to the ground, so that its weight is on the rear suspension. The rear toe setting should be checked, and if necessary adjusted, at the earliest opportunity. Inspection 1The rear hub bearings are non-adjustable, and are supplied complete with the hub. It is not possible to renew the bearings separately from the hub. 2To check the bearings for excessive wear, chock the front wheels, then jack up the rear of the vehicle and support it on axle stands. Fully release the handbrake. 3Grip the rear wheel at the top and bottom, and attempt to rock it. If excessive movement is noted, or if there is any roughness or vibration felt when the wheel is spun, it is indicative that the hub bearings are worn. Renewal 4Remove the rear wheel. 5On drum brake models, remove the rear brake drum as described in Chapter 9. 6On disc brake models, remove the rear brake disc as described in Chapter 9. 7Turning the hub as necessary, line up the hole in the flange with the each of the bolts securing the hub assembly to the rear suspension knuckle; unscrew and remove the bolts (see illustration). 8Withdraw the hub and bearing assembly. Refit two of the hub mounting bolts, to hold the backplate/splash shield in place. 9If necessary, the stub shaft may be removed from the hub for inspection of the bearing, by unscrewing the hub nut. Note that the hub nut is of special laminated design, and may only be re-used a maximum of five times. (It is a good idea to file a small notch on the nut every time it is removed; obtain a new nut if necessary.) Tighten the nut on reassembly. 10Fit the new hub and bearing assembly using a reversal of the removal procedure. Tighten all nuts and bolts to the specified torque. Removal 1Chock the front wheels, then jack up the rear of the vehicle and support it on axle stands. Remove the appropriate rear wheel, and release the handbrake. 2Position a trolley jack or axle stand beneath the rear suspension lower arm, to keep the coil spring in compression. 3Where applicable, remove the ABS sensor as described in Chapter 9. Drum brake models 4Remove the rear brake drum as described in Chapter 9. 5Disconnect the flexible hydraulic brake hose at the bracket on the rear suspension crossmember as described in Chapter 9. Disc brake models 6Remove the rear brake disc as described in Chapter 9. All models 7Remove the rear hub as described in Section 17. 8Remove the backplate or splash shield, as applicable. On drum brake models, support the backplate assembly on an axle stand, to prevent damage to the handbrake cable. 9Unscrew and remove the shock absorber lower mounting bolt. 10Unscrew and remove the three bolts securing the tie-bar to the knuckle. 11Unscrew and remove the bolt securing the front lower arm to the knuckle. 12Unscrew and remove the bolt securing the upper arm to the knuckle. 13Support the knuckle, then unscrew and remove the bolt securing the rear lower arm to the knuckle, and withdraw the knuckle. Refitting 14Refitting is a reversal of the removal procedure, but delay fully tightening the rubber bush mounting bolts until the weight of the vehicle is on the suspension. Tighten all bolts to the specified torque. Where the flexible rear brake hose was disconnected, bleed the hydraulic system as described in Chapter 9. Finally check, and if necessary adjust, the rear wheel toe setting as described in Section 36. Removal 1Chock the front wheels, then jack up the rear of the vehicle and support it on axle stands. Remove the appropriate wheel. 19 Rear shock absorber (Estate models) - removal, testing and refitting 18 Rear suspension knuckle (Estate models) - removal and refitting 17 Rear hub and bearings (Estate models) - inspection and renewal 10•14 Suspension and steering systems 16.8 One of the rear suspension crossmember mounting bolts 17.7 Mounting bolts (arrowed) for the rear hub on Estate models
2Position a trolley jack under the coil spring area of the rear lower suspension arm, to keep the coil spring in compression. 3Unscrew and remove the shock absorber lower mounting bolt (see illustration). 4Unscrew and remove the upper mounting bolt, and withdraw the shock absorber from under the vehicle. Testing 5Check the mounting rubbers for damage and deterioration. If they are worn, they may be renewed separately from the shock absorber body. 6Mount the shock absorber in a vice, gripping it by the lower mounting. Examine the shock absorber for signs of fluid leakage. Test the operation of the shock absorber by moving it through a full stroke, and then through short strokes of 50 to 100 mm. In both cases, the resistance felt should be smooth and continuous. If the resistance is jerky or uneven, the shock absorber should be renewed. Refitting 7Refitting is a reversal of the removal procedure, but tighten the mounting bolts to the specified torque. Removal 1Chock the front wheels, then jack up the rear of the vehicle and support it on axle stands. Remove both rear wheels. 2Unscrew the nuts, and remove the washers and bushes securing the anti-roll bar links to the rear lower arms (see illustrations). 3Using a Torx key, unscrew the bolts securing the anti-roll bar mounting clamps to the rear suspension crossmember; release the clamps, and withdraw the anti-roll bar from under the vehicle (see illustration). 4Examine the rubber bushes for the mounting clamps and links, and if necessary renew them. The links are available individually. Refitting 5Locate the anti-roll bar on the rear crossmember, then refit the clamps and tighten the bolts to the specified torque. 6Refit the anti-roll bar links to the rear lower arms, together with the bushes and washers. Tighten the nuts to the specified torque, while holding the actual links stationary in their central position. 7Refit the rear wheels, and lower the vehicle to the ground. Note:Before attempting to remove the rear suspension coil spring, a tool to hold the coil spring in compression must be obtained. Careful use of conventional coil spring compressors will prove satisfactory. Removal 1Chock the front wheels, then jack up the rear of the vehicle and support it on axle stands.
