CAUTION:
For matching mark, use paint. Do not damage differential
case and drive gear.
16. Remove drive gear mounting bolts.
17. Tap drive gear off differential case assembly with a soft hammer. CAUTION:
Tap evenly all around to keep drive gear from bending.
18. Remove lock pin of pinion mate shaft with a punch from drive gear side.

3. Put matching mark on the end of drive pinion. The matching mark should be in line with the matching mark A on companion
flange.
CAUTION:
For matching mark, use paint. Do not damage companion
flange and drive pinion.
NOTE:
The matching mark A on the final drive companion flange indi-
cates the maximum vertical runout position.
When replacing companion flange, matching mark is not neces-
sary.

3. Temporarily tighten removed drive pinon lock nut to drive pinion.
NOTE:
Use removed drive pinon lock nut only for the preload measure-
ment.
4. Rotate drive pinion at least 20 times to check for smooth opera- tion of the bearing.
5. Tighten to drive pinon lock nut, while adjust pinion bearing pre- load torque.
CAUTION:

Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.

After adjustment, rotate drive pinion back and forth 2 to 3
times to check for unusual noise, rotation malfunction,
and other malfunctions.
6. If the pinion bearing preload torque is outside the specification, use a thicker/thinner drive pinion bearing adjusting washer and drive pinion adjusting washer to adjust.
Refer to FFD-40, "
Drive Pinion Bearing Adjusting Washer" and FFD-40, "Drive Pinion Adjusting Washer" .
7. Remove companion flange, after adjustment.
ASSEMBLY
Drive Pinion Assembly
1. Install front and rear bearing outer races using drifts.
CAUTION:

At first, using a hammer, tap bearing outer race until it
becomes flat to gear carrier.

Do not reuse pinion front and rear bearing outer race. Tool number : ST3127S000 (J-25765-A)
Drive pinion lock nut tightening torque: 127.4 - 245.0 N·m (13 - 25 kg-m, 94 - 181 ft-lb)
Pinion bearing preload: 0.78 - 1.57 N·m (0.08 - 0.16 kg-m, 7 - 13 in-lb)
When the preload torque is large: Decrease the drive pinion bearing adjusting washer and drive pinion adjusting
washer thickness.
When the preload is small: Increase the drive pinion bearing adjusting washer and drive pinion adjusting
washer thickness.

CAUTION:

Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.

After adjustment, rotate drive pinion back and forth 2 to 3
times to check for unusual noise, rotation malfunction,
and other malfunctions.
13. Install differential case assembly. Refer to FFD-34, "
Differential
Assembly" .
CAUTION:
Do not install carrier cover yet.
14. Check and adjust drive gear runout, tooth contact, drive gear to drive pinion backlash, and companion flange runout. Refer to FFD-20, "
Drive Gear Runout" , FFD-21, "Tooth Contact" , FFD-23, "Backlash" ,
FFD-23, "
Companion Flange Runout" .
Recheck above items. Readjust the above description, if necessary.
15. Check total preload torque. Refer to FFD-20, "
Total Preload Torque" .
16. Install carrier cover. Refer to FFD-34, "
