ITooth contact
Check tooth contact. Refer to ªTOOTH CONTACTº, PD-56.
ISide gear to pinion mate gear backlash
Measure clearance between side gear thrust washer and dif-
ferential case with a feeler gauge.
Clearance between side gear thrust washer and differ-
ential case:
0.10 - 0.20 mm (0.0039 - 0.0079 in)

2. Put matchmarks on one side of side bearing cap with paint or
punch to ensure that it is replaced in proper position during
reassembly.
Bearing caps are line-bored during manufacture and should
be put back in their original places.
SPD250
3. Remove side lock fingers and side bearing caps.
