3. Install selected drive pinion height adjusting washer in drive pin-
ion. Using hydraulic press and tool, press-fit pinion rear bearing
inner race into it.
4. Apply multi-purpose grease to pinion rear bearing inner race
and pinion front bearing inner race.
5. Set drive pinion assembly (as shown in figure) in differential car-
rier and install drive pinion, with press and suitable tool.
Stop when drive pinion touches bearing.
6. Install front oil seal with tool. Refer to RFD-7, "
Removal and Installation" .
7. Install companion flange, and tighten drive pinion lock nut to
minimum.
Ascertain that threaded portion of drive pinion and drive pinion
lock nut are free from oil.
CAUTION:
The drive pinion lock nut is not reusable. Never reuse drive
pinion lock nut.Tool number : ST30901000 ( – )

8. Tighten the drive pinion lock nut by very small degrees until the
specified preload in achieved, when checking the preload, turn
drive pinion in both directions several times.

If pinion bearing preload is too small, tighten the drive pinion lock nut more.

If pinion bearing preload is too great, replace pinion bearing adjusting spacer.
INSTALLATION OF DIFFERENTIAL CASE ASSEMBLY
1. Select side bearing adjusting washer.
Refer to RFD-32, "
SIDE BEARING ADJUSTING WASHERS" .
2. Install differential case assembly with side bearing outer races
into gear carrier.
3. Insert original left and right side bearing adjusting washers in
place between side bearings and carrier.
4. Align matching mark on bearing cap with that on gear carrier.
5. Install the side bearing cap.
6. Install side oil seal. Refer to RFD-9, "
Removal and Installation" . Tool number

7. Measure drive gear-to-drive pinion backlash with a dial indicator
at several point.

It backlash is too small, adjustment of washer thickness is required. Decrease thickness of left shim
and increase thickness of right by the same amount.
If backlash is too great, reverse the above procedure.

Never change the total amount of washers as it will change the bearing preload.
8. Check total preload with tool.
When checking preload, turn drive pinion in both directions several times to seat bearing rollers correctly.

If preload is too great, remove the same amount of washer to each side.

If preload is too small, add the same amount of washer to each side.
Never add or remove a different number of washers for each side. Difference in number of washers will
change drive gear to drive pinion backlash.
9. Recheck drive gear to drive pinion backlash. Increase or decrease in thickness of shims will cause
change to drive gear to pinion backlash.

Check whether the backlash varies excessively in different places. Foreign matter may be caught
between the drive gear and the differential case causing the trouble.

The backlash can vary greatly even when the drive gear runout is within a specified range. In that case,
replace the hypoid gear set or differential case.
10. Check runout of drive gear with a dial indicator.
11. Check tooth contact.
Refer to RFD-24, "
TOOTH CONTACT" . Drive gear to drive pinion backlash

Before measuring, move ball joint at least ten times by hand to check for smooth movement.

Hook a spring scale at cotter pin mounting hole. Confirm spring
scale measurement value is within the specifications when ball
stud begins moving.

If it is outside the specified range, replace suspension arm
assembly.
Rotating Torque Inspection

Attach mounting nut to ball stud. Make sure rotating torque is
within the specifications with a preload gauge (SST).

If it is outside the specified range, replace suspension arm
assembly.
Axial End Play Inspection

Move tip of ball joint in axial direction to check for looseness.

If it is outside the specified range, replace suspension arm assembly.Swing torque:
0.5 − 3.4 N·m (0.06 − 0.34 kg-m, 5 − 30 in-lb)
Measured value of spring scale:
