Differentials
(6) Measure the crown gear-to-drive pinion
backlash. Set magnet base on differential car-
rier. 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.
Backlash:
0.10 — 0.20 mm (0.0039 — 0.0079 in)
(7) At the same time, measure the turning
resistance of drive pinion. Compared with the
resistance when
installed, if the increase of the resistance is not
within the specified range, readjust side bearing
retainer shims.
Turning resistance increase:
2.9 — 10.8 N (0.3 — 1.1 kgf, 0.7 — 2.4 lb)
18) Re-check crown gear-to-pinion backlash.
Backlash:
0.10 — 0.20 mm (0.0039 — 0.0079 in)

19) Check the crown gear runout on its back
surface, and make sure pinion and crown gear
rotate smoothly.
Limit of runout:
Less than 0.05 mm (0.0020 in)
