2003 NISSAN X-TRAIL differential

MT-94
FINAL DRIVE

Bearing

Check for bearing damage and rough rotation. If necessary,
replace with a new one.
CAUTION:
When replacing tapered roller bearing, replace outer and inner
races as a set.
ASSEMBLY
1. Apply gear oil to sliding area of differential case, each gear, and thrust washer.
2. Install side gear thrust washers and side gears into differential
case.
3. While rotating pinion mate thrust washers and pinion mate
gears, aligning them diagonally, install them into differential
case.
4. Insert pinion mate shaft into differential case.
CAUTION:
Be sure not to damage pinion mate thrust washers.
5. Measure end play of side gears following the procedure below.
Then select side gear thrust washer.
a. Upright the differential case so that its side gear to be measured
faces upward.
b. Place the drift below and a dial gauge onto side gears.

c. Move side gears up and down to measure end play, and select
thrust washer so that it satisfies the standard value. Refer to MT-
101, "DIFFERENTIAL SIDE GEAR THRUST WASHER" .
CAUTION:

There should be no resistance and gears should rotate
freely.

Place differential case upside down. Be sure to measure
end play for opposite side-gears likewise.

Only one thrust washer can be selected.
6. Install a new retaining pin into pinion mate shaft using a pin
punch.
CAUTION:
Do not reuse retaining pin.
7. Press in differential side bearing (transaxle case side) to differ-
ential case using the drifts.
8. Press in differential side bearing (clutch housing side) to differ-
ential case using the drifts.
9. Install final gear into differential case, and tighten final gear
mounting bolts to the specified torque. Refer to MT-28, "
FINAL
DRIVE COMPONENTS" . End play standard value
: 0.1 - 0.2 mm (0.004 - 0.008 in)
