CAUTION:

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

If the preload torque exceeds the specified value, replace
collapsible spacer and tighten it again to adjust. Do not
loosen drive pinion lock nut to adjust the preload torque.
6. Make a stamping for identification of front oil seal replacement
frequency. Refer to RFD-10, "

ASSEMBLY INSPECTION AND ADJUSTMENT

Before inspection and adjustment, drain gear oil.
Total Preload Torque
1. Secure final drive assembly onto an attachment.
2. Remove side flanges.
3. Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
4. Rotate drive pinion at least 20 times to check for smooth opera-
tion of the bearing.
5. Measure total preload with the preload gauge.
NOTE:
Total preload torque = Pinion bearing preload torque + Side
bearing preload torque

If measured value is out of the specification, disassemble it to
check and adjust each part. Adjust the pinion bearing preload and side bearing preload.
Adjust the pinion bearing preload first, then adjust the side bearing preload.
Drive Gear Runout
1. Remove rear cover. Refer to RFD-22, "Differential Assembly" .
2. Fit a dial indicator to the drive gear back face.
3. Rotate the drive gear to measure runout.

If the runout is outside of the repair limit, check drive gear
assembly condition; foreign material may be caught between
drive gear and differential case, or differential case or drive gear
may be deformed, etc.
CAUTION:
Replace drive gear and drive pinion gear as a set.Tool number A: KV38100800 (J-25604-01)
Tool number A: ST3127S000 (J-25765-A)
Total preload torque:
2.84 - 3.75 N·m (0.29 - 0.38 kg-m, 26 - 33 in-lb)
PDIA0766J
When the preload torque is large
On pinion bearings: Replace the collapsible spacer.
On side bearings: Use thinner side bearing adjusting washers by the same amount to
each side. Refer to RFD-38, "
Side Bearing Adjusting Washer" .
When the preload is small
On pinion bearings: Tighten the drive pinion lock nut.
On side bearings: Use thicker side bearing adjusting washers by the same amount to
each side. Refer to RFD-38, "
Side Bearing Adjusting Washer" .
Runout limit: 0.05 mm (0.0020 in)

For matching marks, use paint. Do not damage differential
case and drive gear.
11. Remove drive gear mounting bolts.
12. Tap drive gear off differential case assembly with a soft hammer.
CAUTION:
Tap evenly all around to keep drive gear from bending.
13. Remove lock pin of pinion mate shaft with a punch from drive
gear side.
14. Remove pinion mate shaft.
15. Turn pinion mate gear, then remove pinion mate gear, pinion
mate thrust washer, side gear and side gear thrust washer from
