that front and rear parallel links on axle side be loosened (not removed). This will facilitate wheel align-
ment inspection and adjustment which are carried out later.
2. As shown in the figure, use a wheel wrench or similar tool to
remove drive shaft from rear final drive.
INSPECTION AFTER REMOVAL

Move the joint in the up/down, left/right, and axial directions. Check for any rough movement or significant
looseness.

Check boot for cracks or other damage, and also for grease leakage.
INSTALLATION
1. In order to prevent damage to rear final drive side oil seal, first fit
a protector (SST) onto oil seal before inserting drive shaft. Slide
drive shaft into slide joint and tap with a hammer to install
securely.
