2004 INFINITI FX35 differential

RFD-28
REAR FINAL DRIVE ASSEMBLY
Revision: 2004 November 2004 FX35/FX45
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
