REASSEMBLY
1. ASSEMBLE DIFFERENTIAL CASE
(a) Using SST and a press, install 2 new needle bearings.

09950−70010 (09951−07150)
Bearing press in depth: 2.0 mm (0.079 in.)
(b) Install the 2 proper thrust washers on the side gears.
HINT:
Refer to the table below to select thrust washers which will en-
sure that the backlash is within specifications.
Washer thickness
Thickness mm (in.)Thickness mm (in.)
0.96 − 1.04 (0.0378 − 0.0409)1.16 − 1.24 (0.0457 − 0.0488)
1.06 − 1.14 (0.0417 − 0.0449)1.26 − 1.34 (0.0496 − 0.0528)
(c) Install the 2 side gears, pinion gears, pinion gear thrust
washers and pinion shaft in the differential case.
HINT:
Align the holes of the differential case and pinion shaft.
(d) Using a dial indicator measure the side gear backlash
with holding one pinion gear toward the differential case.
Backlash: 0.05 − 0.20 mm (0.0020 − 0.0079 in.)
If the backlash is not within the specification, install side gear
thrust washers with different thicknesses.
