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.

DISASSEMBLY

Differential Assembly

1. Drain the differential gear oil if necessary.

If the backlash is greater than specification:

Loosen side bearing adjuster (A) and tighten side 
bearing adjuster (B) by the same amount.

If the backlash is less than specification:

Loosen side bearing adjuster (B) and tighten side 
bearing adjuster (A) by the same amount.

7. For proper reinstallation, paint matching marks on one side of

the side bearing cap and gear carrier.

CAUTION:

• For matching marks, use paint. Do not damage side bear-

ing cap or gear carrier.

• Side bearing caps are line-board during manufacture. The

matching marks are used to reinstall them in their original

positions.

8. Remove the side bearing caps.

9. Remove the side bearing adjuster.

10. Lift the differential case assembly out of the gear carrier. 

CAUTION:

Keep side bearing outer races together with side bearing

inner races. Do not mix them up.

11. Remove side bearing inner race using Tools as shown.

CAUTION:

• Do not remove side bearing inner race unless it is being

replaced.

• Place copper plates between the vise and the side bearing

inner race and drive gear to prevent damage.
