DIFFERENTIALS
(3) Install side retainer shims to the left and
right retainers from which they were removed.
NOTE:
• Replace broken or cracked O-ring with new one.
• Replace broken or corroded side retainer shim
with new one of same thickness.

(4) Align arrow marked on differential carrier
with that marked on side retainer during installa-
tion.
NOTE:
Be careful that side bearing outer race is not dam-
aged by bearing roller.

(5) Tighten side bearing retainer bolts.

(6) Measure the crown gear-to-drive pinion
backlash. Set magnet base on differential carri-
er. Align contact point of dial gauge with tooth
face of crown gear, and move crown gear while
holding drive pinion still. Read value indicated
on dial gauge.
When backlash is out of standard range, adjust
side retainer shim with the following procedure.
When backlash is more than 0.20 mm (0.0079
in):
Reduce shim thickness on crown gear back, in-
crease shim thickness on crown gear side.
When backlash is less than 0.10 mm (0.0039
in):
Increase shim thickness on crown gear back, re-
duce shim thickness on crown gear side.
Backlash:
0.10 — 0.20 mm (0.0039 — 0.0079 in)
(7) At the same time, measure the turning resis-
tance of drive pinion. Compared with the resis-
tance when differential case is not installed,
when turning resistance increase is out of stan-
dard value, adjust by both increasing and de-
creasing with the same amount of side bearing
retainer shim thickness.
Turning resistance increase:
2.9 — 10.8 N (0.3 — 1.1 kgf, 0.7 — 2.4 lb)
16) Re-check crown gear-to-pinion backlash.
Backlash:
0.10 — 0.20 mm (0.0039 — 0.0079 in)
