4. Rotate the drive pinion using Tool. Rotating torque should be
equaltothereadingrecordedinstep4aboveduringremoval
plus an additional 0.56 N·m (5 in-lb).
5. If the rotating torque is low, continue to tighten the drive pinion
lock nut in 6.8 N·m (5 ft-lb) increments without overtightening.
Refer toRFD-15, "
COMPONENTS". Tighten until proper rotat-
ing torque is achieved.
CAUTION:
lDo not loosen the drive pinion lock nut to decrease drive
pinion rear bearing rotating torque.
lDo not exceed specified rotating preload torque. If preload torque or rotating torque is exceeded
a new collapsible spacer must be installed.
lDo not exceed maximum tightening torque. If maximum tightening torque is reached prior to
reaching the required rotating torque, the collapsible spacer may have been damaged. Replace
the collapsible spacer.
6. Check the gear oil level. Refer toRFD-9, "
Checking Differential Gear Oil".
7. Install the remaining components in the reverse order of removal.Tool number : ST3127S000

ASSEMBLY INSPECTION AND ADJUSTMENT
lBefore inspection and adjustment, drain gear oil.
Total Preload Torque
1. Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
2. Rotate drive pinion at least 20 times to check for smooth operation of the bearing.
3. Turn drive pinion in both directions several times to set bearing
rollers.
4. Measure total preload with preload gauge.
NOTE:
Total preload torque = Pinion bearing preload torque + Side bearing preload torque
lIf measured value is out of the specification, disassemble it to check and adjust each part. Adjust pinion
bearing preload and side bearing preload.
Adjust pinion bearing preload first, then adjust side bearing preload.
Tooth Contact
Checking gear tooth contact pattern is necessary to verify correct relationship between drive gear and drive
pinion. Gears which are not positioned in proper arrangement may be noisy and/or have a short life. Check
gear tooth contact pattern to obtain the best contact for low noise and long life.
1. Remove carrier cover. Refer toRFD-13, "
Removal and Installation".
2. Thoroughly clean drive gear and drive pinion teeth.
3. Apply red lead to drive gear.
CAUTION:
Apply red lead to both the faces of 3 to 4 gears at 4 loca-
tions evenly spaced on drive gear.Tool number : ST3127S000
