AdjustmentNBPD0020For quiet and reliable final drive operation, the following five adjust-
ments must be made correctly:
1. Side bearing preload
2. Pinion gear height
3. Pinion bearing preload
4. Ring gear-to-pinion backlash. Refer to SDS, PD-37.
5. Ring and pinion gear tooth contact pattern
SPD527
SIDE BEARING PRELOADNBPD0020S01A selection of carrier side bearing adjusting washer is
required for successful completion of this procedure.
1. Make sure all parts are clean and that the bearings are well
lubricated with light oil or ªDEXRON
TMº type automatic trans-
mission fluid.
2. Place the differential carrier, with side bearings and bearing
races installed, into the final drive housing.
SPD894
3. Put the side bearing spacer in place.
CAUTION:
Side bearing spacer is placed on either the right or left
depending upon final drive gear ratio. Be sure to replace it on
the correct side.
SPD986
4. Using Tool, install original carrier side bearing preload shims
on the carrier end, opposite the ring gear.
Tool number: KV38100600 (J25267)
SPD526
5. Install the side bearing caps in their correct locations and
torque the bearing cap retaining bolts.
Specification:
88 - 98 N´m (9 - 10 kg-m, 65 - 72 ft-lb)
6. Turn the carrier several times to seat the bearings.

6. Install differential case assembly on ring gear.
7. Apply locking agent [Locktite (stud lock) or equivalent] to ring
gear bolts, and install them.
Tighten bolts in a criss-cross pattern, lightly tapping bolt head
with a hammer.

2. Select drive pinion height adjusting washer and pinion bearing
adjusting washer. Refer to ªPINION GEAR HEIGHT AND PIN-
ION BEARING PRELOADº, PD-25.
3. Install drive pinion height adjusting washer in drive pinion, and
press-fit pinion rear bearing inner cone in it, using press and
Tool.

9. Tighten differential case couple bolts.
10. Place ring gear on differential case and tighten ring gear bolts.
Tighten bolts in a criss-cross pattern, lightly tapping bolt head
with a hammer.
Then bend up lock straps to lock the bolts in place.
11. Install side bearing inner cone.
12. Check differential torque.
AdjustmentNBPD0040For quiet and reliable final drive operation, the following five adjust-
ments must be made correctly:
1. Side bearing preload
2. Pinion gear height
3. Side bearing preload
4. Ring gear-to-pinion backlash. Refer to SDS, PD-62.
5. Ring and pinion gear tooth contact pattern

PINION GEAR HEIGHTNBPD0040S011. Make sure all parts are clean and that the bearings are well
lubricated.
2. Assemble the pinion gear bearings into the pinion pre-load
shim selector tool, J34309.
SPD197A
IRear Pinion BearingÐ the rear pinion bearing pilot,
J34309-8, is used to center the rear pinion bearing only. The
rear pinion bearing locking seat, J34309-4, is used to lock the
bearing to the assembly.
IFront Pinion BearingÐ make sure the J34309-3, front pin-
ion bearing seat is secured tightly against the J34309-2 gauge
anvil. Then turn the front pinion bearing pilot, J34309-5, to
secure the bearing in its proper position.

3. Place the pinion preload shim selector tool gauge screw
assembly, J34309-1, with the pinion rear bearing inner cone
installed, into the final drive housing.
