Limited-slip differential gear
+ Use only approved or recommended limited-slip differential
gear oil.
+ Limited-slip differential identi®cation.
(1) Lift both rear wheels off the ground.
(2) Turn one rear wheel by hand.
(3) If both rear wheels turn in the same direction simultaneously, vehicle is equipped with limited-slip differential.
Checking Front Wheel Bearing Grease
+Check that wheel bearings operate smoothly.
+ Check front wheel bearings for grease leakage and water or
dust entry.
+ Replace front wheel bearings or front wheel bearing grease if
wheel bearings do not turn smoothly.

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.

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.

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.

Disassembly
1. Remove side bearing inner cone with Tool.
2. Loosen ring gear bolts in a criss-cross pattern.
3. Tap ring gear off gear case with a soft hammer.
Tap evenly all around to keep ring gear from binding.
4. Loosen screws on differential cases A and B using a press.
5. Separate differential cases A and B. Draw out component parts
(discs and plates, etc.).
Put marks on gears, discs and plates so that they can be rein-
stalled in their original positions from which they were
removed.
Inspection
CONTACT SURFACES
1. Clean the disassembled parts in suitable solvent and blow dry
with compressed air.
2. If following surfaces are found with burrs or scratches, smooth
with oil stone.

4. Install pressure ring.
5. Install side gear by inserting projected portion of disc.
6. Install pinion mate gears and shaft.
Always attach pinion mate shaft to ``V'' groove in pressure ring
with ¯at surfaces facing up and down.
7. Install thrust block.
8. Install differential case A side components in the opposite way
of differential case B components.
9. Apply gear oil to differential case A, and attach thrust washer
to it.
