Removal and Installation





CAUTION: Before removing the axle shaft, remove the ABS sensor to reposition the ABS sensor out of the way. Failure to do so may result in damage to the ABS sensor and cause the ABS sensor to become inoperative.

REMOVAL
1. Remove the ABS sensor.
2. Remove the rear brake rotor. Refer to Removal and Installation of Brake Caliper and Disc Rotor.
3. Remove the parking brake assembly from the back plate.





4. Remove the four axle shaft bearing cage nuts and lock washers





5. Remove the axle shaft assembly using Tools as shown.

CAUTION:
^ The axle shaft bearing cup may stay in place in the axle shaft housing. Remove the cup carefully so as not to damage the inner surface of the axle shaft housing.
^ Do not reuse the axle oil seal. The axle oil seal must be replaced every time the axle shaft assembly is removed from the axle shaft housing.

Tool number A: KV40101000 (J-25604-01)
Tool number B: ST36230000 (J-25840-A)
6. Remove the snap ring from the axle shaft using suitable snap ring pliers.





7. Secure the axle shaft in a suitable vise, then use a 1/4 in size drill bit to drill a hole approximately 3/4 into the thickness of the bearing ring retainer [3/4 thickness is approximately 6.3 mm (0.25 inch) deep].

CAUTION:
^ Mount the axle shaft using a soft jaw vise to avoid damaging the axle shaft.
^ Do not drill all the way through the bearing ring retainer, the drill may damage the axle shaft surface.





8. Strike the bearing ring retainer using a suitable chisel and hammer, with the chisel positioned across the drilled hole. Break the bearing ring retainer to remove it.

CAUTION: Do not heat or cut the axle shaft bearing or bearing ring retainer with a torch during removal, doing so will damage the axle shaft.

9. Remove the axle shaft bearing cage studs using a suitable hammer or press.
10. Pull the axle shaft bearing off of the axle shaft using Tool and a suitable press.
Tool number: 205-D002

CAUTION:
^ Do not tighten the Tool against the axle shaft.
^ Do not heat or cut the axle shaft bearing or bearing ring retainer with a torch during removal, doing so will damage the axle shaft.

11. Remove the axle oil seal and discard.

CAUTION: Do not reuse the axle oil seal. The axle oil seal must be replaced every time the axle shaft assembly is removed from the axle shaft housing.

12. Remove the wheel bearing cage.

NOTE:
^ If reinstalling the old axle shaft, it may not be necessary to remove the ABS sensor rotor. Inspect the ABS sensor rotor and replace as necessary.
^ The ABS sensor rotor cannot be reused after it is removed. If replacing the axle shaft, install a new ABS sensor rotor on the new axle shaft.

INSPECTION AFTER REMOVAL
Axle Shaft
^ Clean and remove all nicks and burrs.
^ Check for straightness and distortion. Replace if necessary.
^ Inspect machined surfaces for evidence of overheating, damage and wear. Replace if necessary.
^ Measure the bearing ring retainer axle journal diameter. Replace if necessary.
Bearing ring retainer axle journal diameter (minimum): 39.726 mm (1.5640 inch)

Axle Shaft Bearing and Cup
^ Check that the axle shaft bearing and cup roll freely and are free from noise, cracks, pitting and wear. Replace if necessary.

Axle Shaft Bearing Cage
^ Check for deformation and cracks. Replace if necessary.

Axle Shaft Housing
^ Check the exterior and inner machined surfaces for deformation and cracks. Replace if necessary.

INSTALLATION
1. If installing a new axle shaft, install a new ABS sensor rotor onto the new axle shaft.

CAUTION: Do not reuse the old ABS sensor rotor.

2. Install the axle shaft bearing cage.
3. Install a new axle oil seal.

CAUTION: Do not reuse the axle oil seal. The axle oil seal must be replaced every time the axle shaft assembly is removed from the axle shaft housing.





4. Install the axle shaft bearing and cup on the axle shaft.
^ Prepare an installer tool from a steel tube measuring 762 mm (30 inch) long with an outside diameter of 53.98 mm (2.125 inch) and an inside diameter of 41.28 mm (1.625 inch).
^ Press the axle shaft bearing and cup onto the axle shaft using a suitable press and the installer tool, until a 0.038 mm (.0015 inch) feeler gauge does not fit in between the axle shaft bearing cup and seat.

CAUTION: Make sure the axle shaft bearing and cup, axle oil seal, and axle shaft bearing cage are installed facing in the correct direction.

5. Install the bearing ring retainer onto the axle shaft.
^ Press the bearing ring retainer onto the axle shaft with a minimum force of 31,100 N (3172 kg, 6992 lb) until a 0.038 mm (0.0015 inch) feeler gauge does not fit between the bearing inner race and the bearing ring retainer in at least one point.
6. Install the snap ring so it is fully seated into the groove on the axle shaft, using suitable snap ring pliers.
7. Install the axle shaft assembly into the axle shaft housing.
8. Install the axle shaft bearing cage lock washers and nuts. Tighten the axle shaft bearing cage nuts to specification.
9. Install the parking brake assembly onto the back plate.
10. Install the rear brake rotor. Refer to Removal and Installation of Brake Caliper and Disc Rotor.
11. Install the rear ABS sensor.
