DRIVE PINION

Select the correct standard pinion height adjusting washer thick-
ness. Select by using a standard gauge of 3 mm (0.12 in) and
your 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.

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

Set a dial indicator (A) vertically to the tip of the drive pinion.

Rotate drive pinion to check for runout.

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.

Conditions and Measures

Hypoid gear

• If the gear teeth do not mesh or line-up correctly, determine the cause and adjust or replace as nec-

essary.

• 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

• If any chipped (by friction), pitted, worn, rusted or scratched mark, or unusual noise from the bearing

is observed, replace as a bearing assembly (as a new set).

Side gear and pinion mate
gear

• 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.

Side gear thrust washer and
pinion mate thrust washer

• If it is chipped (by friction), damaged, or unusually worn, replace.

Oil seal

• Whenever disassembled, replace.
• If wear, deterioration of adherence (sealing force lips), or damage is detected on the lips, replace them.

Differential case

• If any wear or crack on the contact sides of the differential case is found, replace.

Companion flange

• If any chipped mark (about 0.1 mm, 0.004 in) or other damage on the contact sides of the lips of the

companion flange is found, replace.
