Step 22: Change if required, the adjustment shims of
differential supports to reach the specified pre-load,
(rolling torque of 1.5-3.0 Ib-ft (0.2-0.4 daNvn).
Step 23: Smear ring gear teeth with red lead and mount
the complete pinion support on the center section case,
without using sealing compound on matching surfaces.
Lock assembling screws with a torque of 55-61 Ib-ft
(7.5-8.3 daNm).
Step 24: Fit fixture to differential case, to bring to the
outside, the middle diameter of bevel ring gear. Position
a dial gauge to record specified backlash on pinion-and-
ring gear 0.008-0.011 in. (0.20-0.28 mm), ring gear
must be moved closer to the pinion if backlash is higher,
or moved away if it is low. This adjustment must not vary
value of shims fitted for adjusting bearing pre-load.
Shims should be displaced from one support to other to
displace ring gear as required. Rotate pinion to
emphasize red lead contact marks on teeth,
disassemble pinion to check pattern.
