Be careful not to confuse right and left side retainers and
shims.
5. Extract differential case from final drive housing.
6. Remove side outer races.Tool number:ST33290001
Be careful to keep the side bearing outer races together with
their respective inner cones Ð do not mix them up.

Differential Case
1. Remove side bearing inner cones.
To prevent damage to bearing, engage puller jaws in grooves.Assembly:ST33065001

Be careful not to confuse the right and left hand parts.
2. Loosen ring gear bolts in a criss-cross fashion.
3. Tap ring gear off differential case with a soft hammer.
Tap evenly all around to keep ring gear from binding.
4. Separate L.H. and R.H. differential cases.
Put match marks on both L.H. and R.H. differential cases.

1. Remove differential side shaft assembly from extension tube.
2. Cut rear axle bearing collar with cold chisel. Be careful not todamage differential side shaft.
3. Install differential side shaft into extension tube and secure with bolts. Remove extension tube retainer from differential side
shaft.
4. Remove grease seal.

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 and thrust washers.
Bearing
1. Thoroughly clean bearing.
2. Check bearings for wear, scratches, pitting or flaking.Check tapered roller bearing for smooth rotation. If damaged,
replace outer race and inner cone as a set.

Extension Tube and Differential Side Shaft
1. Measure rear axle bearing end play.Rear axle bearing end play (A þ B):0.1 mm (0.0039 in) or less
The end play can be adjusted with bearing adjusting shim.
(Refer to PD-57.)
2. Install oil seal.
3. Install the spacer, grease seal, extension tube retainer, adjust- ing shim, shim and shim collar onto the differential side shaft.
4. Install differential side shaft assembly into extension tube.

Differential Case
1. Measure clearance between side gear thrust washer and dif-ferential case.Clearance between side gear thrust washer and differ-
ential case (A þ B): 0.10 - 0.20 mm (0.0039 - 0.0079 in)
The clearance can be adjusted with side gear thrust washer.
(Refer to PD-57.)
2. Apply gear oil to gear tooth surfaces and thrust surfaces and check to see the turn properly.
3. Install L.H. and R.H. differential cases.
4. Place differential case on ring gear.
5. Apply locking agent [Locktite (stud lock) or equivalent] to ring gear bolts, and install them.
Tighten bolts in a criss-cross fashion, lightly tapping bolt head
with a hammer.
6. Press-fit side bearing inner cones on differential case with Tool. Tool number:q

12. Place the differential case assembly in its housing.
13. Install side oil seal.
14. Place side retainer adjusting shims and O-ring on side retainer,and install them in final drive housing.Tool number: ST33720000
I Align arrows stamped on side retainer and final drive housing.
15. Measure ring gear-to-drive pinion backlash with a dial indicator. Ring gear-to-drive pinion backlash:0.13 - 0.18 mm (0.0051 - 0.0071 in)
I If backlash is too small, decrease thickness of right shim and
increase thickness of left shim by the same amount.
If backlash is too great, reverse the above procedure.
Never change the total amount of shims as it will change the
bearing preload.
