PROPELLER SHAFTS Freelander15 1. Cylinder 2. Slotted discs 3. Input shaft4. Roller bearing 5. Ball bearing 6. Output shaft The rear wheels are 0.8% under driven, so in most conditions the vehicle is effectively front wheel drive, with the rear wheels turning the rear propeller shaft slightly faster than the IRD drives the front propeller shaft. Since the speed differential is low, the increase in viscosity of the silicon jelly is marginal and there is little resistance to relative rotation of the...

PROPELLER SHAFTS 18 NEW RANGE ROVER DRIVE AND PROPELLER SHAFTS GENERAL The front drive shafts are handed components with the RH drive shaft being longer than the LH drive shaft. Both shafts are of similar construction with constant velocity (CV) joints at each end to allow for steering and suspension movement. The rear drive shafts are identical with a CV joint at each end to allow for suspension movement. Propeller shafts are used to transmit drive from the transfer box to the front and rear...

Inner CV joint The outer CV joint has a target on the outer diameter. This is used by the ABS wheel speed sensor for vehicle and wheel speed calculations. Refer to the Braking section for further details. Each drive shaft consists of two CV joints and gaiters, an outer tube, a solid shaft and a ball cage assembly.

PROPELLER SHAFTS New Range Rover21 The CV joints are of the Birfield design. This design uses longitudinal, elliptical grooves which retain six steel balls. The balls are further retained by a cage. The constant velocity is achieved by the position of the steel balls. If a centre line is drawn through the balls and the driven hub or differential shaft, the two centre lines always bisect each other at the angle of drive. This condition allows the rotational speed of the driven shaft to be passed to the...

Inner CV joint The rear drive shafts are identical in their construction. Each drive shaft has a total length of 687 mm. The inner CV joint has six holes for attachment with bolts to the differential output flange. Each pair of bolts is fitted with shim which secures the bolts after tightening. The outer CV joint has a target on the outer diameter. This is used...

Circlip The CV joints used on the rear drive shafts are of the Birfield design. Refer to the Front Drive Shafts for a description of the CV joints. The outer CV joint is retained on the tube by an internal snap ring. The CV joint can be removed by a sharp tap with a soft mallet on the CV joint housing which...

Seal The front propeller shaft is constructed from 2.1 mm wall tubular steel. A three arm coupling is welded at one end. The opposite end has a splined shaft welded to the tube. The shaft has an overall length of 752 mm. The three arm coupling has three holes which allow for attachment to the coupling and the coupling adaptor. The coupling adaptor and the coupling...
