Service Procedure

ABS Rotor Ring Removal (if equipped)

1. Remove the rear axle from the vehicle using the procedure listed in the applicable service manual. Stand the axle up on its wheel studs (splined end of the axle is facing upward).

2. Remove the ABS Rotor Ring (using the components in the J-45073 kit) as follows:





A. Slide the sleeve P/N J-25852-4 over the extension tube P/N J-45073-12 (see Figure 1a).

B. Slide the extension tube P/N J-45073-12 (with sleeve P/N J-25852-4) over the vehicle's axle shaft (see Figure lb).





C. Install the two halves of the collet P/N J-45073-2 around the ABS rotor ring making sure the lower lip of each collet is slid under the rotor ring (see Figure 2a).

D. Slide the sleeve (P/N J-25852-4) over the two halves of the collet (see Figure 2b).

E. Tighten the forcing screw of the extension tube until the rotor ring is pulled free (see Figure 2c). Do not use an impact wrench to tighten the forcing screw.

F. Remove the sleeve, collets, extension tube, and rotor ring from the axle shaft.

Brake Backing Plate Removal (with inner axle bearing)

1. Clamp the vehicle's axle shaft (on the wheel studs) in a vise.

NOTE:
Use soft jaws when clamping the wheel studs.





2. Bend down the tabs of the bearing locknut lockwasher with a hammer and punch (see Figure 3).





3. Install the bearing lock nut wrench P/N J-45073-1 on the axle locknut (see Figure 4a).

4. Loosen and remove the axle locknut (see Figure 4b).

5. Slide the extension tube and sleeve over the vehicle's axle shaft (see Figure 1b).





6. Install the two halves of the bearing puller jaw P/N J-45073-7 over the brake backing plate studs (see Figure 5a).

7. Slide the sleeve P/N J-25852-4 over the bearing puller jaw halves (see Figure 5b).

8. Install a nut on each brake backing plate stud (see Figure 5c).

9. Tighten the forcing screw of the extension tube until the brake backing plate (with inner wheel bearing) is pulled free (see Figure 5d).

IMPORTANT:
Do not use an impact wrench to tighten the forcing screw.

10. Remove the sleeve, bearing puller jaws, extension tube, and backing plate (with inner axle bearing) from the axle shaft.

11. If needed, press the inner axle bearing race out of the backing plate using conventional pressing methods.

Outer Axle Bearing Removal (from axle shaft)

1. Slide the extension tube and sleeve over the vehicle's axle shaft (see Figure 1b).





2. Install the two halves of the bearing puller jaw PIN J-45073-7 around the outer axle bearing making sure the lower lip of each jaw is slid under the bearing (see Figure 6a).

3. Slide the sleeve P/N J-25852-4 over the bearing puller jaws (see Figure 6b).

4. Tighten the forcing screw of the extension tube until the axle bearing is pulled free (see Figure 6c).

IMPORTANT:
Do not use an impact wrench to tighten the forcing screw.

5. Remove the sleeve, bearing puller jaws, extension tube, and outer bearing from the axle shaft.

NOTE:
The inner axle bearing race (that remains in the brake backing plate) can be removed using the conventional press removal method.

6. Re-assemble the axle shaft assembly according to the applicable service manual procedures. Use bearing lock nut wrench P/N J-45073-1 to tighten the axle lock nut to the specification listed in the applicable service manual.





NOTE:
When tightening the axle shaft lock nut, make sure the lock nut wrench (P/N J45073-1) is installed on the torque wrench at 90 degrees (see Figure 7) to achieve the most accurate torque application.

7. Re-install the axle shaft assembly in the vehicle according to the applicable service manual procedures.
