FRONT FINAL DRIVE
Backlash
1. Fit a dial indicator to the drive gear face to measure the back-
lash.
• If the backlash is outside of the specification, adjust each side
bearing adjuster.
CAUTION:
Do not change the side bearing adjusters by different
amounts as it will change the side bearing preload torque.
Companion Flange Runout
1. Rotate companion flange and check for runout on the compan-
ion flange face (inner side of the bolt holes) and companion
flange inner side (socket diameter) using suitable tool.
2. If the runout is outside the runout limit, follow the procedure
below to adjust.
a. Rotate the companion flange on the drive pinion by 90
°, 180° and 270° while checking for the position
where the runout is minimum.
b. If the runout is still outside of the runout limit after the companion flange has been rotated on the drive pin-
ion, possible cause could be an assembly malfunction of drive pinion and drive pinion bearing or a mal-
functioning drive pinion bearing.
c.
If the runout is still outside of the runout limit after repair of the assembly of drive pinion and drive pinion
bearing or drive pinion bearing, replace the companion flange.
