Differential Carrier
1. Mount differential carrier on Tools.
Tool number:
j
AST0501S000
j
BST06340000
2. Put matchmarks on one side of side bearing cap with paint or
punch to ensure that it is replaced in proper position during
reassembly.
Bearing caps are line-bored during manufacture and should
be put back in their original places.
3. Remove side lock ®ngers and side bearing caps.
4. Remove side bearing adjuster with Tool.
Tool number:
ST32580000
5. Remove differential case assembly with a pry bar.

Be careful to keep the side bearing outer races together with
their respective inner cones Ð do not mix them up.
6. Loosen drive pinion nut with Tool.
Tool number: KV38104700
7. Remove companion ¯ange with puller.
8. Take out drive pinion together with pinion rear bearing inner
cone, drive pinion bearing spacer and pinion bearing adjusting
shim with soft hammer.
9. Remove front oil seal and pinion front bearing inner cone.
10. Remove pinion bearing outer races with a brass drift.

11. Remove pinion rear bearing inner cone and drive pinion heightadjusting washer with press and Tool.Toolnumber:ST30031000 (J22912-01)
Differential Case
1. Remove side bearing inner cones.
To prevent damage to bearing, engage puller jaws in groove. Tool number:j
AST33051001 (J22888-20)
j
BST02371000 (J8107-2)
Be careful not to confuse left and right hand parts.
Keep bearing and bearing race for each side together.
2. Loosen ring gear bolts in a criss-cross pattern.
3. Tap ring gear off differential case with a soft hammer.
Tap evenly all around to keep ring gear from binding.
4. Drive out pinion mate shaft lock pin, with punch from ring gear side (2-pinion type differential case).
Lock pin is calked at pin hole mouth on differential case.

case).
Put matchmarks on both differential case LH and RH sides
prior to separating them.

Ring Gear and Drive Pinion
Check gear teeth for scoring, cracking or chipping. If any damaged
part is evident, replace ring gear and drive pinion as a set (hypoid
gear set).
Differential Case Assembly
Check mating surfaces of differential case, side gears, pinion mate
gears, pinion mate shaft, thrust block and thrust washers.
Bearing
1. Thoroughly clean bearing.
2. Check bearings for wear, scratches, pitting or ¯aking.
Check tapered roller bearing for smooth rotation. If damaged,
replace outer race and inner cone as a set.

CAUTION:
Do not run engine when one wheel (rear) is off the ground.
Preparation for Disassembly
CHECKING DIFFERENTIAL TORQUE
Measure differential torque with Tool.
If it is not within the speci®cations, inspect components of limited
slip differential.
Differential torque:
108 - 137 Nzm (11 - 14 kg-m, 80 - 101 ft-lb)
