1. DIFFERENTIAL CASE ASSEMBLY

1. Install the differential bevel gear and differential bevel pinion together with adjusting washer, and insert the pinion shaft.

NOTE:

Face the chamfered side of adjusting washer toward differential bevel gear.

(A)	Pinion shaft
(B)	Differential bevel pinion
(C)	Differential bevel gear
(D)	Adjusting washer

2. Measure the backlash between the differential bevel gear and differential bevel pinion. Adjust the backlash if not within specified limit. Front Differential Assembly > INSPECTION

NOTE:

Be sure the differential bevel pinion gear teeth contact adjacent gear teeth during measurement.

Standard backlash

0.13 — 0.18 mm (0.0051 — 0.0071 in)

3. Align the pinion shaft pin hole with the differential case pin hole, and drive the straight pin into the holes from the hypoid driven gear side using the ST.

NOTE:

Use a new straight pin. After driving, crimp the area around the hole, and make sure that the straight pin will not come out.

4. Install the taper roller bearing.

CAUTION:

Do not apply a load in excess of 10 kN (1 ton, 1.1 US ton, 1.0 Imp ton).

NOTE:

Be careful when handling because the taper roller bearing and the outer race are used as a set.

(A)	Hypoid driven gear
(B)	Differential case

2. DIFFERENTIAL SIDE RETAINER

1. Using the ST, install the oil seal by lightly tapping with a plastic hammer.

NOTE:

• Use a new oil seal.

• Apply transmission gear oil to the oil seal lips, and install the oil seal while being careful not to deform the lip.

• Check the identification marks (L, R), and attach the oil seals RH and LH.

2. Install the O-rings.

NOTE:

• Use new O-rings.

• Apply transmission gear oil to O-ring.

• Do not stretch or damage the O-ring.

• Install the O-ring after hypoid driven gear backlash adjustment and completion of tooth contact inspection.
