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.
215
^ 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.
