2. Alloy wheels: Lightly coat wheel mounting spigot face with
a suitable anti-seize compound to minimise possibility of
adhesion between wheel and spigot face.
3. Refit wheel taking care not to damage stud threads. (Do not
apply oil).
4. Fit wheel nuts and turn by hand for at least three full
threads before using any form of wheel wrench.
5. Tighten nuts as much as possible using a suitable wrench.
6. Lower vehicle and finally tighten nuts to correct torque
sequence shown.

9. Reassemble ball joints, packing with Dextagrease G.P. or
equivalent. Renew joints if worn.
10. Check condition of gaiters and renew if necessary.
Installation

CVX on ball pin threads.
2. Fit upper ball joint to self-levelling unit and secure gaiter.
3. Fit top bracket complete with levelling unit to chassis and
secure with 4 nuts and tighten to 47 Nm (35 lbf/ft).
4. Fit self-levelling unit to lower ball joint and secure gaiter.
5. Attach webbing strap to chassis cross member.
6. Fit upper links to the pivot bracket and retain with 2 bolts
and nuts but do not tighten at this stage.

Driveshaft - Driveshaft
Description and Operation
Description
The front and rear drive shafts have non-constant velocity type universal joints, with needle roller bearings. The bearing
cups are pre-packed with lubricant on assembly and a grease nipple is fitted for servicing as specified, in maintenance
section.
Both shafts have ball splines to accommodate the variation in distance between the axles and transmission. The splines
are pre-packed with lubricant and protected by a rubber gaiter.
• NOTE: This joint does not require lubrication.
The front and rear driveshafts are 'phased', with the joints at each end, A and B mis-aligned as shown.
The phasing is necessary to allow for greater variation in angular changes. On reassembly it is essenital the driveshafts
are realigned correctly.

Vibration Harshness
Check the propeller shaft universal joints are not seized or worn by checking for excessive radial and axial movement.
This can be done by inserting a suitable lever into the joint and checking for movement. In the event that both shafts
are satisfactory, but the vibration/harshness is still present, the transfer box operation and balance of the road wheels
should be checked.
