sembly.
(3) Install the side retainer shims to the right
and left retainers from which they were re-
moved.
NOTE:
Replace the broken or corroded side retainer shim
with a new one of same thickness.

(6) Measure the crown gear-to-drive pinion
backlash. Set the magnet base on differential
carrier. Align the contact point of dial gauge with
tooth face of crown gear, and move the crown
gear while holding drive pinion still. Read the
value indicated on dial gauge.
Backlash:
0.10 — 0.20 mm (0.0039 — 0.0079 in)
(7) At the same time, measure the total preload
of drive pinion. Compared with the resistance
when differential case is not installed, if the total
preload is not within specification, adjust the
thickness of side bearing retainer shims, in-
creasing/reducing by an even amount at a time.
Total preload:
20.7 — 54.4 N (2.1 — 5.5 kgf, 4.7 — 12.2 lb)
15) Re-check the crown gear-to-pinion backlash.
Backlash:
