REPAIR PROCEDURE
INSPECT DRIVESHAFT ENGAGEMENT
1. Carry out the following steps to verify if disengagement of a driveshaft is the cause of the complaint:
^ Raise the vehicle so the front wheels are freely suspended.
^ Verify that there is no visible gap between the front driveshaft inboard joint and the differential housing on the left-hand side. (Insert "check mark" in Figure 1)
^ Verify that there is no visible gap between the front inboard joint and the engine sump on the right-hand side. (Insert "Check mark" in Figure 1)
CAUTION:
If the driveshaft retaining circlip is disengaged, manual force alone will be sufficient to move the driveshaft inboard joint from its correct location (Dashed arrow in Figure 1). Tools or levers should NOT be used as this may cause the disengagement of the circlip.
NOTE:
Marginal driveshaft retaining circlip engagement, can cause an intermittent condition. Therefore it is important that circlip engagement be checked carefully.
^ Inspect both of the front drive shafts and verify they are fully engaged into the differential.
^ Manually check the security of the drive shaft inboard joint into the differential housing.
REPAIR OR REPLACE DRIVESHAFT
NOTE:
GTR lookup sequence is as follows: GTR Home > North America > Service Information/LM New Range Rover/2005 > Workshop Manuals > Service Procedures > Bookmark "DRIVESHAFTS/REPAIRS" > link "Drive shaft - front - LH or RH"
1. If driveshaft disengagement is identified as the root cause, refer to GTR Workshop Manual Section 46.10.01 or 47.10.02 and remove the affected driveshaft.
2. Inspect the driveshaft for damage that could affect retention of the new circlip.
3. If the driveshaft is not damaged, perform the following:
^ Install a new retaining circlip and re-install the original driveshaft.
^ Manually check the security of the drive shaft inboard joint into the differential housing.
^ Claim driveshaft remove and replace as a separate warranty repair.
4. If the driveshaft is damaged, perform the following:
^ Install a new driveshaft and circlip.
^ Manually check the security of the drive shaft inboard joint into the differential housing.
