Nissan Frontier D22. Manual - part 890

RFD-68

[H233B]

REAR FINAL DRIVE ASSEMBLY

Place pinion front bearing inner cone in gear carrier.

Apply multi-purpose grease to cavity at sealing lips of oil seal.
Install front oil seal.

Install drive pinion bearing spacer, pinion bearing adjusting shim
and drive pinion in gear carrier.

Install ABS sensor unit and sensor rotor (2WD models).

Insert companion flange onto drive pinion. Tap the companion
flange with a soft hammer until fully seated

Tighten pinion nut until total preload is within specification.

●

The threaded portion of drive pinion and pinion nut
should be free from oil or grease.

10. Turn drive pinion in both directions several times, and measure

pinion bearing preload using Tool.

If preload is out of specification, adjust the thickness of spacer
and shim combination by replacing shim and spacer with thinner
one.

●

Start from the combination of thickest spacer and shim.

●

Combine each spacer and shim thickness one by one until the correct specification are achieved.

INSTALLATION OF DIFFERENTIAL CASE

Install differential case assembly with side bearing outer races into gear carrier.

Position side bearing adjusters on gear carrier with threads
properly engaged; using Tool, screw in adjusters lightly at this
stage of assembly.

Align mark on bearing cap with that on gear carrier and install
bearing cap on gear carrier.

●

Do not tighten at this point. This allows further tightening of
side bearing adjusters.

Tighten both right and left side bearing adjusters alternately and
measure ring gear backlash and total preload at the same time.
Adjust right and left side bearing adjusters by tightening them
alternately so that proper ring gear backlash and total preload
can be obtained.

REAR FINAL DRIVE ASSEMBLY

●

When checking preload, turn drive pinion in both direc-
tions several times to set bearing rollers using Tool.

Tighten side bearing cap bolts.

Install side lock finger in place to prevent rotation during opera-
tion.

Check runout of ring gear with a dial indicator.

●

If backlash varies excessively in different places, the variance
may have resulted from foreign matter caught between the
ring gear and the differential case.

●

If the backlash varies greatly when the runout of the ring gear
is within a specified range, the hypoid gear set or differential
case should be replaced.

Check tooth contact. Refer to
