DRIVE PINION
• Pinion front bearing; make sure the J-34309-3 pinion front
bearing seat is secured tightly against the J-34309-2 gauge
anvil. Then turn the pinion front bearing pilot, J-34309-5, to
secure the bearing in its proper position.
• Pinion rear bearing; the pinion rear bearing pilot, J-34309-8,
is used to center the pinion rear bearing only. The pinion rear
bearing locking seat, J-34309-4, is used to lock the bearing to
the assembly.
• Installation of J-34309-9 and J-34309-16; place a suitable
2.5 mm (0.098 in) thick plain washer between J-34309-9 and
J-34309-16. Both surfaces of J-34309-9 and J-34309-16 must
be parallel with a clearance of 2.5 mm (0.098 in).
3.
Install the pinion rear bearing inner race into gear carrier. Then
place the pinion preload shim selector tool, J-34309-1, gauge
screw assembly.
4.
Assemble the pinion front bearing inner race and the J-34309-2
gauge anvil. Assemble them together with the J-34309-1 gauge
screw in gear carrier. Make sure that the pinion height gauge
plate, J-34309-16, turns a full 360 degrees. Tighten the two sec-
tions together by hand.
5.
Turn the assembly several times to seat the bearings.
6.
Measure the turning torque at the end of the J-34309-2 gauge
anvil using preload gauge [SST: ST3127S000 (J-25765-A)].

7.
Place the J-34309-11 “R200A” pinion height adapter onto the
gauge plate and tighten it by hand.
CAUTION:
Make sure all machined surfaces are clean.
8.
Position the side bearing discs, J-25269-4, and arbor firmly into
the side bearing bores. Install the bearing caps and tighten bear-
ing cap mounting bolts to the specified torque. Refer to
9.
Select the correct standard pinion height adjusting washer thick-
ness. Select by using a standard gauge of 3 mm (0.12 in) and J-
34309-101 feeler gauge. Measure the distance between the J-
34309-11 pinion height adapter including the standard gauge
and the arbor.
10. Write down exact measurement (the value of feeler gauge).
11. Correct the pinion height washer size by referring to the “pinion
head number”.
There are two numbers painted on the drive pinion. The first
one refers to the drive pinion and drive gear as a matched
set. This number should be the same as the number on the
drive gear. The second number is the “pinion head height
number”. It refers to the ideal pinion height from standard
for quietest operation. Use the following chart to determine
the correct pinion height washer.

DRIVE PINION
12. Select the correct pinion height adjusting washer.
13. Remove the J-34309 differential shim selector tool from the final
drive housing. Then disassemble to retrieve the pinion bearings.
DRIVE PINION RUNOUT
1.
Set a dial indicator (A) vertically to the tip of the drive pinion.
2.
Rotate drive pinion to check for runout.
3.
If the runout value is outside of the limit, possible causes are an
assembly malfunction of drive pinion and pinion bearing and
malfunction of pinion bearing. Check for these items and repair if
necessary.

DRIVE GEAR AND DRIVE PINION
• Clean up the disassembled parts.
• If the gear teeth never mesh or line-up correctly, determine the cause and adjust or replace as necessary.
• If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new drive
gear and drive pinion as a set.
BEARING
• Clean up the disassembled parts.
• If any chipped (by friction), pitted, worn, rusted or scratched marks, or unusual noise from the bearing is
observed, replace as a bearing assembly (as a new set).
SIDE GEAR AND PINION MATE GEAR
• Clean up the disassembled parts.
• If any cracks or damage on the surface of the tooth is found, replace.
• If any worn or chipped mark on the contact sides of the thrust washer is found, replace.
