the plate washers to where there is no play in the
bearing (See page RA±42)
(b) Install bearing caps. (See page RA±44)
(c) Using a dial indicator, measure the runout of ring gear.
Maximum runout: 0.07 mm (0.0028 in.) Using a hammer and drift punch, stake the lock
plates.
HINT: Stake one claw flush with the flat surface of
the nut. For the claw contacting the protruding por-
tion of the nut, stake only the half on the tightening
side.
3. INSTALL SIDE BEARINGS
Using a press and SST, drive in the side bearings into
the differential case.

ing or decreasing the number of washers on both

Insure that there is ring gear backlash.(g) Place the other plate washer onto the differential
case together with the outer race, and install the

rier. (e) Select a ring gear teeth side washer with a thick-
ness which eliminates any clearance between
the outer race and case.

(f) If not within the standard, adjust by either increasing or de-
creasing the washers on both sides by equal amount.

in.) with 0.03 mm (0.0012 in.) alteration of the side washer.(b) Install a new plate washer of 0.06 ± 0.09 mm
