Axle, Traction-Lok Limited Slip Differential—8.8 Inch Ring Gear

In-vehicle adjustments are possible on this unit without removing the differential case from the axle assembly. If the testing check was not to specification, the following procedure can be used to correct the condition:

NOTE: Whenever replacing the rear axle lubricant, use Rear Axle Lubricant XY-90-QL (ESP-M2C154-A) or equivalent.

Removal

1. Raise the vehicle on a hoist and install safety stands. Refer to Section 00-02. Remove rear wheels and brake drums. If equipped with disc brakes remove caliper and rotor. Refer to Section 06-04.

2. Remove cover from carrier rear face and drain lubricant.

3. Perform the inspection before disassembly.

4. Working through the cover opening, remove the pinion shaft lock bolt and remove the pinion shaft.

5. Push axle shafts inward until the C-locks at the button end of shafts are clear of the side gear recess.

    CAUTION: Care should be taken not to damage the wheel seals when removing the axle shafts from the axle housing. In addition, the axle shafts must be completely removed from the axle housing.

6. Remove the C-locks and pull the axle shafts out of the housing.
   
   
   
   

    WARNING: CARE MUST BE USED WHEN REMOVING THE PRELOAD SPRING DUE TO SPRING TENSION.

7. With a suitable drift, drive the S-shaped preload spring half-way out of the differential case. Rotate the differential case 180 degrees.

8. Hold the S-shaped preload spring with a pair of pliers and tap the spring until it is removed from the differential.

   NOTE: A 304.8mm (12 inch) extension is required to remove the pinion gears.

9. Using Gear Rotator-Traction-Lok T80P-4205-A, rotate the pinion gears until the gears can be removed from the differential.
   
   
   
   

10. Remove the RH and LH side gear and clutch pack with the shim and tag them "RH" and "LH" side.

    NOTE: Do not use cleaning solution on clutch plate surfaces. Wipe clean only.

11. Inspect the clutch packs for wear and replace parts as necessary.

12. Install Traction-Lok Clutch Gauge T80P-4946-A on each of the side gear clutch packs without the shim. Tighten to 6.7 Nm (60 lb-in).
    
    
    
    

    NOTE: Lubricate friction plates with Additive Friction Modifier C8AZ-19B546-A (EST-M2C118-A) or equivalent hypoid gear lubricant prior to reassembly.

13. Using a feeler blade, select the thickest blade that will enter between the tool and the clutch pack. This reading will be the thickness of the new shim.
    
    
    
    

Installation

1. Install the LH side gear, clutch pack and new shim into the cavity in the differential case. Repeat this step for the RH side.

2. Place the pinion gears and thrust washers 180 degrees apart on the side gears.

   NOTE: A 304.8mm (12 inch) extension is required to install the pinion gears.

3. Install Gear Rotator-Traction-Lok T80P-4205-A in differential case.
   
   
   
   

4. Rotate the tool until the pinion gears are aligned with the pinion shaft hole. Remove the tool from the differential case.
   
   
   
   

   NOTE: Inspect the preload spring for damage.

5. Hold the S-shaped preload spring up to the differential case window and with a soft-faced hammer, hammer the spring into position.

6. Install the axle shafts and C-locks into position. Push the axle shaft outboard as far as possible.

   NOTE: Lock bolt must be tightened to specification using Stud and Bearing Mount E0AZ-19554-BA (WSK-M2G349-A1) or equivalent.

7. Install the pinion shaft and pinion shaft lock bolt. Tighten the bolt to 20-40 Nm (15-30 lb-ft).

8. Install the rear brake drums and wheels. If equipped with disc brakes install brake rotors and calipers. Refer to section 06-04. Perform the Traction-Lok operational check to ensure that the unit is within specification.

9. Using Silicone Rubber D6AZ-19562-AA or BA (ESE-M4G195-A) or equivalent, install the rear cover assembly and bolts. Tighten to 34-47 Nm (25-35 lb-ft).

10. With vehicle level, fill axle 6-14mm (1/4-9/16 inch) below bottom of filler hole with axle lubricant and add 118 ml (4 oz) of Friction Modifier C8AZ-19B546-A (EST-M2C118-A) or equivalent.

11. Install oil filler plug. Tighten to 20-41 Nm (15-30 lb-ft).
