INSPECTION
Gear, washer, shaft and case
ICheck mating surfaces of differential case, side gears and
pinion mate gears.
ICheck washers for wear.
Bearing
IMake sure bearings roll freely and are free from noise, cracks,
pitting or wear.
IWhen replacing tapered roller bearing, replace outer and
inner race as a set.
ASSEMBLY
1. Attach side gear thrust washers to side gears, then install pin-
ion mate washers and pinion mate gears in place.
2. Insert pinion mate shaft.
IWhen inserting, be careful not to damage pinion mate
thrust washers.
3. Measure clearance between side gear and differential case
with washers using the following procedure:
a. Set Tool and dial indicator on side gear.
b. Move side gear up and down to measure dial indicator deflec-
tion. Always measure indicator deflection on both side gears.
Clearance between side gear and differential case
with washers:
0.1 - 0.2 mm (0.004 - 0.008 in)
c. If not within specification, adjust clearance by changing thick-
ness of side gear thrust washers.
