(d)

Check the side gear backlash.
Measure the side gear backlash while holding one pinion
gear toward the case.

Standard backlash:

0.05-0.20 mm (0.0020-0.0079 in.)

Refering to the table below, select thrust washers which
will ensure that the backlash is within specification. Try to
select washers of the same size for both sides.

Thrust washer thickness

mm (in.)

Thickness mm (in.)

Thickness mm (in.)

1.60 (0.0630)

1.70 (0.0670)

1.80 (0.0709)

If the backlash is not within specification, install a thrust
washer of a different thickness.

(e)

Using a pin punch and hammer, drive the lock pin through
the case and hole in the pinion shaft.

(f)

Stake the differential case.

2.

INSTALL RING GEAR

(a)

Clean the contact surface of the differential case.

(b)

Heat the ring gear to about 100

°

C (212

°

F) in an oil bath.

NOTICE: Do not heat the ring gear above 110

°

C (230

°

F).

(c)

Carefully remove the ring gear from the oil bath.

(d)

Clean the contact surface of the ring gear with cleaning
solvent.

(e)

Quickly install the ring gear on the differential case.
