For 1990-2009 cars

#### Tools Required

• | J 28509-A Side Bearing Puller

• | J 34851 Puller Adapter

• | J 34842 Bearing Installer

• | J 7079-2 Driver Handle

• | J 8001 Dial Indicator Set

### Removal Procedure

1. Using a J 28509-A with a J 34851 , remove the LH differential side bearing (7055) from the differential carrier.
2. Using a J 28509-A with a J 34851 , remove the speedometer drive gear (7057) and the RH differential side bearing (7055) from the differential carrier.
3. Using a drift punch remove the pinion shaft roll pin (7059) from the differential carrier (7052).

Remove the following parts from the differential carrier (7052) (Refer to Differential Components ):

• | Pinion shaft

• | Pinion gears

• | Side gears

• | Ring gear retaining bolts

• | Ring gear

4. Clean all parts thoroughly with solvent. Air dry.
5. Inspect the following parts:

• | Gear teeth, for signs of damage and excessive or uneven wear

• | Pinion gear washers and side gear washers, for signs of excessive wear, distortion or damage

### Installation Procedure

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

1. Install the following parts to the differential carrier (7052) (Refer to Differential Components ):

• | The side gear washers and the side gears.

• | The pinion gear washers and the pinion gears.

• | The pinion gear shaft and the pinion shaft roll pin.

• | The ring gear (7053) and the eight retaining bolts (7054).

Tighten
Tighten the ring gear retaining bolts to 90 N·m (65 lb ft).

2. Using a J 34851 and a hydraulic press, identified in the illustration by the number 1, install the speedometer drive gear (7057). Place the gear on the press support and center the differential carrier (7052) and slowly press the differential carrier into the drive gear.
3. Using a J 34842 with a J 7079-2 , install the differential side bearings (7055). With the seal side of the bearings facing the carrier, tap the bearings onto the carrier evenly.
4. Using a J 8001 measure the left differential side gear end play. Place the J 8001 plunger between the teeth of the left differential side gear and move the left differential side gear up and down using two screwdrivers. Observe the J 8001 .
5. Standard left differential side gear end play should be between 0.05-0.33 mm (0.002-0.013 in). If the left differential side gear end play falls below 0.05 mm (0.002 in), replace the left side gear selective shim with the appropriate selective shim in order to obtain proper left differential side gear end play. Refer to Side Gear Selective Shim Specifications Side Gear Selective Shims Table.
6. Using a J 8001 measure the right differential side gear end play. Place the J 8001 plunger on the rear of the right differential side gear and gently move the right differential side gear up and down using the fingertips of both hands. Observe the J 8001 .
7. Standard right differential side gear end play should be between 0.05-0.33 mm (0.002-0.013 in). If the right differential side gear end play falls below 0.05 mm (0.002 in), replace the right side gear selective shim with the appropriate selective shim in order to obtain proper left differential side gear end play. Refer to Side Gear Selective Shim Specifications Side Gear Selective Shims Table.
