INSPECTION AFTER DISASSEMBLY
Clean up the disassembled parts. Then, inspect if the parts are worn or damaged. If so, follow the measures
below.

Tool number A: ST30031000 (J-22912-01)
PDIA0801J
PDIA0677E
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.

9. If the turning torque is outside the specification, use a thicker/ thinner side bearing adjusting shim to adjust. Refer to FFD-39,
"Inspection and Adjustment".
10. Record the total amount of shim thickness required for the cor- rect carrier side bearing preload.
Pinion Gear Height
If the hypoid gear set has been replaced, se lect the pinion height adjusting washer.
1. Use the formula below to calculate pinion height adjusting washer thickness.
2. Select the proper pinion height adjusting washer. Refer to FFD-39, "
Inspection and Adjustment".
If impossible find the desired thickness of washer, us e washer with thickness closest to the calculated
value.
Pinion Bearing Preload
Assemble the drive pinion parts if they are disassembled. Refer to "Drive Pinion Assembly".
1. Make sure all parts are clean. Also, make sure the bearings are well lubricated with gear oil.
2. Install companion flange (1). NOTE:
When reusing drive pinion, align the matching mark (B) of drive
pinion with the matching mark (A) of companion flange, and then
install companion flange (1).If the turning torque is l
ess than the specified range:
Decrease the side bearing adjusting shim thickness.
If the turning torque is gr eater than the specification:
Increase the side bearing adjusting shim thickness.

Washer selection equation:
T = T
0 + (t1 - t2)
T: Correct washer thickness
T
0: Removed washer thickness

1: Old drive pinion head letter “H × 0.01”
(“H”: machined tolerance 1/100 mm × 100)
t
2: New drive pinion head letter “H × 0.01”
(“H”: machined tolerance 1/100 mm × 100)
Example:
T = 3.21 + [(2 × 0.01) - (-1 × 0.01)] = 3.24
