(5) 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.
NOTE:
If measured backlash is not within specified range,
repeat procedures for pinion crown gear set back-
lash adjustment and differential side bearing pre-
load adjustment.
Backlash:
0.10 — 0.15 mm (0.0039 — 0.0059 in)
15) Draw a matching mark on both differential car-
rier and holder. Remove holder one side at a time.
