6. Measure the turning torque of the carrier at the drive gear retain-
ing bolts with a spring gauge, J-8129.
7. If the turning torque is not within the specifications, correct the
torque as follows:

If the turning torque is less than the specified range, install
washers of greater thickness.

If the turning torque is greater than the specification, install
thinner washers.

See the SDS section for washer dimensions and part num-
bers.
8. Record the total amount of washer thickness required for the
correct carrier side bearing preload.
9. Remove the carrier from the final drive housing. Save the
selected washers for later use during the assembly of the final
drive unit.
PINION GEAR HEIGHT
1. Make sure all parts are clean and that the bearings are well
lubricated.
2. Assemble the pinion gear bearings into the differential shim
selector tool, J34309.

Pinion front bearing; make sure the J34309-3 pinion front bear-
ing seat is secured tightly against the J34309-2 gauge anvil.
Then turn the pinion front bearing pilot, J34309-5, to secure the
bearing in its proper position.

Pinion rear bearing; the pinion rear bearing pilot, J34309-8, is
used to center the pinion rear bearing only. The pinion rear bear-
ing locking seat, J34309-4, is used to lock the bearing to the
assembly.Specification

Installation of J34309-9 and J34309-16; place a suitable 2.5 mm (0.098 in) thick plain washer between
J34309-9 and J34309-16. Both surfaces of J34309-9 and J34309-16 must be parallel with a clearance of
2.5 mm (0.098 in).
3. Install the pinion rear bearing inner race into the final drive hous-
ing. Then place the pinion preload shim selector tool, J34309-1,
gauge screw assembly.
4. Assemble the pinion front bearing inner race and the J34309-2
gauge anvil. Assemble them together with the J34309-1 gauge
screw in the final drive housing. Make sure that the pinion height
gauge plate, J34309-16, will turn a full 360 degrees. Tighten the
two sections together by hand.
5. Turn the assembly several times to seat the bearings.
6. Measure the turning torque at the end of the J34309-2 gauge
anvil using torque wrench J-25765A.

7. Place the J34309-11 “R200A” pinion height adapter onto the
gauge plate and tighten it by hand.
CAUTION:
Make sure all machined surfaces are clean.
Pinion Height Adjusting Washer Selection
1. Now, position the side bearing discs, J25269-4, and arbor firmly
into the side bearing bores. Install the bearing caps and tighten
the cap bolts to proper torque.
2. Select the correct standard pinion height adjusting washer thick-
ness. Select by using a standard gauge of 3 mm (0.12 in) and
your J34309-101 feeler gauge. Measure the distance between
the J34309-11 pinion height adapter including the standard
gauge and the arbor.
3. Write down your exact measurement (the value of feeler gauge).

AND SEALANTS" to drive gear bolts, and install them.
CAUTION:
Do not reuse the bolts. Always replace the bolts with a new
one.

Tighten bolts in a crisscross fashion.

After tightening the bolt to the specified torque, turn the bolt
31 to 36 more degrees.
4. Press-fit side bearing inner race on differential case with tool.
INSTALLATION OF DRIVE PINION ASSEMBLY
1. Press-fit front and rear bearing outer races with tools.
