PROPELLER SHAFTS 1 FAULT DIAGNOSIS VIBRATION HARSHNESS 1.Check that the propeller shaft universal joints and sliding splines are not siezed or worn and that the shafts are correctly aligned. NOTE: In the event that both shafts are satisfactory, but the vibration/harshness is still present, the transfer box and balance of the road wheels should be checked. For transfer box faults. See TRANSFER GEARBOX, Fault diagnosis, Borg Warner Symptoms For balance of road wheels.See WHEELS AND TYRES, Repair, Wheel Balancing

REAR AXLE AND FINAL DRIVE 1 DESCRIPTION AND OPERATION DESCRIPTION The welded steel rear axle casing houses a separate spiral bevel type differential unit, which is off set to the right of the vehicle centre line. The differential unit drives the rear wheels via the axle shafts and fully floating hubs which are mounted on tapered roller bearings. Lubrication The differential is lubricated with oil and the hub bearings with grease. The hub bearings are fittedwith inner and outer seals. The outer seals prevent the differential oil mixing with the hub grease and the inner seals prevent dirt ingress into the hub. Ventilation Ventilation of the hub bearings is through the outer oil seals and the differential ventilation pipe, which terminates at a high level. The wheel hubs on axles with ABS brakes share the same construction to non ABS axles except for the addition of a sensor ring 11 on the brake disc 10. Rear axle hub 1. Axle casing 2.

REAR AXLE AND FINAL DRIVE 1 FAULT DIAGNOSIS FAULT DIAGNOSIS Complaint - Oil leaks An external leak of lubrication from the hub seals can be caused by a faulty internal seal. For example, if the internal seals which separate the differential from the hubs are faulty and the vehicle is operating or parked on an embankment. Oil from the differential may flood one hub causing a leak and leave the differential lacking lubrication. When a seal is found to be leaking check the axle ventilation system, as a blockage can cause internal pressure to force oil past the seals. See Description and Operation for illustrations of oil seal locations. When investigating hub seal leaks check the grease for dilution with oil. Check also the differential level and oil for metal particles and the condition of internal seals. If the vehicle is driven in deep water with defective oil seals, water may contaminate the lubricants and raise the differential level giving a false impression that the housing has been overfilled with oil. Do not assume that a high oil level in the differential is due to over filling or, that a low level is because of an external leak.
