DRIVE PINION
9.
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
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.
A/T : Inspection After Disassembly
INFOID:0000000001714291
Clean up the disassembled parts. Then, inspect if the parts are worn or damaged. If so, follow the measures
below.

Content
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.
