Using a plastic-faced hammer, tap out the bearing retainer.

Remove the differential case from the differential carrier.

Set the differential carrier to an overhaul stand as shown in the illustration.

Using a press, press out the drive pinion.

NOTICE:

Do not drop the drive pinion.

Remove the bearing (inner race) from the differential carrier.

Replace the bearing spacer with a new one.

Remove any old FIPG material and be careful not to drop oil on the contact surfaces of the differential carrier and shaft bearing retainer.

Wipe off any residual FIPG material on the contact surface using gasoline or alcohol.

Apply seal packing to the differential carrier as shown in the illustration.

Seal packing:

Toyota Genuine Seal Packing 1281, Three Bond 1281 or equivalent

Seal Diameter (A):

2.0 to 3.0 mm (0.0788 to 0.118 in.)

HINT:

Install the shaft bearing retainer within 10 minutes of applying seal packing.

Install the front differential cross shaft bearing retainer and front differential front support assembly LH with the 11 bolts (A) and 3 new bolts (B).

Torque:

for bolt A:

65 N*m{663 kgf*cm, 48 ft.*lbf}

for bolt B:

155 N*m{1581 kgf*cm, 114 ft.*lbf}

NOTICE:

Do not add oil or drive the vehicle immediately after installing the cover, and leave it as is for at least an hour. Also, for 12 hours or less, avoid rapid acceleration/deceleration.

Using SST and a hammer, lightly tap in the bearing (inner race) to install it.

Limit Torque Value:

451 N*m (4599 kgf*cm, 332ft.*lbf) or less

Using a torque wrench, measure the preload of the backlash between the drive pinion and ring gear.

Standard Preload (at Starting):

Bearing	Specified Condition
New	2.97 to 3.47 N*m (31 to 35 kgf*cm, 27 to 30 in.*lbf)
Reused	2.14 to 2.45 N*m (22 to 24 kgf*cm, 19 to 21 in.*lbf)

Torque:

451 N*m{4599 kgf*cm, 333 ft.*lbf}or less

HINT:

Standard Total Preload (at Starting):

Bearing	Specified Condition
New	4.58 to 5.88 N*m (47 to 59 kgf*cm, 41 to 52 in.*lbf)

Install the front differential carrier (Click here).

Add differential oil so that the oil level is between 0 to 5 mm (0 to 0.197 in.) from the bottom lip of the differential filler plug hole.

NOTICE:

1. Too much or too little oil will lead to differential problems.
   
2. After changing the oil, drive the vehicle and then check the oil level again.
