REAR FINAL DRIVE ASSEMBLY
• Drain the differential gear oil before inspection and adjustment. Refer to
DLN-194, "Changing Differential
• Remove and install the carrier cover as necessary for inspection and adjustment. Refer to
Total Preload Torque
1. Rotate the drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
2. Rotate the drive pinion at least 20 times to check for smooth operation of the bearings.
3. Measure total preload torque using Tool. Refer to
.
• If the measured value is out of the specification, check and
adjust each part. Adjust the drive pinion bearing preload
torque first, then adjust the side bearing preload torque.
NOTE:
Total preload torque = Drive pinion bearing preload torque +
Side bearing preload torque
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. Thoroughly clean drive gear and drive pinion teeth.
2. Apply red lead to the drive gear.
• Apply red lead to both faces of three to four gears, at four loca-
tions evenly spaced on the drive gear.
3. Hold companion flange steady by hand and rotate drive gear in
both directions.
Tool number
: ST3127S000 (J-25765-A)
If the total preload torque is greater than specification
On drive pinion bearings
: Replace collapsible spacer.
On side bearings
: Loosen side bearing adjuster.
If the total preload torque is less than specification
On drive pinion bearings
: Tighten drive pinion lock nut.
On side bearings
: Tighten side bearing adjuster.

Backlash
1. Fit a dial indicator to the drive gear face to measure the back-
lash.
2. If the backlash is outside of the specification, adjust each side bearing side bearing adjuster.
a. Remove adjuster lock plates.
b. Loosen side bearing cap bolts.
c. Tighten or loosen each side bearing adjuster using Tool.

REAR FINAL DRIVE ASSEMBLY
CAUTION:
Do not change the side bearing side bearing adjusters by
different amounts as it will change the side bearing preload
torque.
d. Tighten side bearing cap bolts to the specified torque.
e. Install adjuster lock plate and tighten to the specified torque.
CAUTION:
Check tooth contact and total preload torque after adjusting
side bearing adjuster. Refer to
Companion Flange Runout
1. Rotate companion flange and check for runout on the compan-
ion flange face (inner side of the bolt holes) and companion
flange inner side (socket diameter) using suitable tool. Refer to
DLN-208, "General Specification"
.
2. If the runout is outside the runout limit, follow the procedure
below to adjust.
a. Rotate the companion flange on the drive pinion by 90
°, 180°
and 270
° while checking for the position where the runout is
minimum.
b. If the runout is still outside of the runout limit after the companion
flange has been rotated on the drive pinion, possible cause
could be an assembly malfunction of drive pinion and drive pin-
ion bearing or a malfunctioning drive pinion bearing.
c.
If the runout is still outside of the runout limit after replacing the companion flange. Replace the rear final
drive assembly. Refer to
DLN-198, "Removal and Installation"
DISASSEMBLY
Differential Assembly
1. Remove carrier cover bolts.
2. Remove carrier cover using Tool.
CAUTION:
• Do not damage the mating surface.
• Do not insert flat-bladed screwdriver, this will damage the
mating surface.
If the backlash is greater than specification:
Loosen side bearing adjuster A and tighten side bear-
ing adjuster B by the same amount.
If the backlash is less than specification:
Loosen side bearing adjuster B and tighten side bear-
ing adjuster A by the same amount.
