DISASSEMBLY
1. REMOVE REAR DIFFERENTIAL CARRIER COVER
(a) Remove the 8 bolts from the carrier cover.
(b) Using a brass bar and a hammer, separate the
carrier cover from rear differential carrier assembly.
(c) Remove the breather plug from the rear differential
carrier cover.

cover.
2. FIX REAR DIFFERENTIAL CARRIER ASSEMBLY
3. INSPECT RUNOUT OF DIFFERENTIAL RING GEAR
(a) Using a dial gauge, check the runout of the ring
gear.
Maximum runout:
0.07 mm (0.0028 in.)
If the runout is greater than the maximum, replace
the ring gear with a new one.
4. INSPECT DIFFERENTIAL RING GEAR BACKLASH
(a) Using a dial gauge, check the backlash of the ring
gear.
Backlash:
0.13 to 0.18 mm (0.0051 to 0.0071 in.)
If the backlash is not within the specification, adjust
the side bearing preload or repair as necessary.

gear while holding 1 pinion gear toward the
differential case.
Backlash:
0.05 to 0.20 mm (0.0020 to 0.0079 in.)
If the backlash is not within the specification, install
the 2 side gear thrust washers of differential
thickness (See page DF-26).
