NOTE:
• Apply gear oil on both sides of the washer and on
the side gear shaft before installing.
• Insert the pinion mate shaft into the differential
case by aligning the lock pin holes.
(1) Measure the side gear backlash.
Side gear back clearance:
0.10 — 0.20 mm (0.0039 — 0.0079 in)
(2) Adjust the backlash as specified by select-
ing the side gear thrust washer.
