Adjustment of Differential Case

1. CHECK SIDE GEAR BACKLASH
Measure the backlash of one side gear while holding one pinion toward the case.

Standard backlash: 0.05 - 0.20 mm (0.0020 - 0.0079 in.)

If the backlash is out of specification, install the correct thrust washer to the side gears.




2. DISASSEMBLE DIFFERENTIAL CASE
a. Drive out the pinion shaft lock pin from the side on which the ring gear is installed.




b. Remove the pinion shaft from the case.
c. Remove the two pinions, two side gears and four thrust washers.




3. ASSEMBLE DIFFERENTIAL CASE
a. Install the removed thrust washers to the side gears.




b. Install the side gears with thrust washers, pinion thrust washers and pinion gears.
c. Install the pinion shaft.







d. Check the side gear backlash.
Measure the side gear backlash while holding one pinion gear towards the case.

Standard backlash: 0.05 - 0.20 mm (0.0020 - 0.0079 in.)

e. Refering to the table, select thrust washers which will ensure that the backlash is within specification. Try to select washers of the same size of both sides.
f. If the backlash in not within specification, install a thrust washer of different thickness.




g. Install the lock pin.
1. Using a hammer and punch, drive the lock pin through the case and hole in the pinion shaft.
2. Stake the differential case.
