Clearance between Differential Case Bore (Differential Case
Cover Bore) and Differential Side Gear Boss
1. Measure the bore I.D. of the differential case and differential case
cover.
2. Measure the differential side gear boss O.D. and calculate the
clearance.
3. If the clearance exceeds the allowable limit, replace them.
W10284030
Clearance between Differential Pinion Shaft and Differential
Pinion
1. Measure the differential pinion shaft O.D.
2. Measure the differential pinion I.D. and calculate the clearance.
3. If the clearance exceed the allowable limit, replace them.
W10287600
Backlash between Differential Pinion and Differential Side Gear
1. Set a dial indicator (lever type) on the tooth of the differential
pinion.
2. Hold the differential side gear and move the differential pinion to
measure the backlash.
3. If the measurement is not within the factory specifications, adjust
with the differential side gear washer.
(Reference)
• Thickness of differential side gear washer :
1.5 mm (0.059 in.) 1.7 mm (0.067 in.)
1.6 mm (0.063 in.)
