Tone Wheel

OVERVIEW
This procedure is for the removal of the ABS rear tone wheel from the rear hub and bearing on front wheel drive vehicles. Vehicles equipped with AWD have a tone wheel mounted on the driveshaft outer constant velocity joint and it is serviced with the driveshaft.

REMOVE
1. Raise vehicle on jackstands or centered on a frame contact type hoist. See Hoisting in Maintenance for required lifting procedure.
2. Remove the wheel and tire assembly.
3. Remove rear brake drum from the hub/bearing assembly.






4. Remove the rear wheel speed sensor from the rear hub/bearing flange . This will prevent damage to the speed sensor during removal and installation of the hub/bearing assembly.






5. Remove the 4 bolts attaching the hub/ bearing assembly to the flange of the rear axle.






6. Remove the hub/bearing assembly from the rear axle and brake support plate.






7. Install wheel lug nuts on 3 of the wheel mounting studs to protect the stud threads from damage by the vise jaws. Mount the hub/bearing assembly in a vise. Using Puller, Special Tool C-4693 installed as shown, remove the tone wheel from the hub/bearing assembly.

INSTALL






1. Place hub/bearing assembly in an arbor press supported by Receiver, Special Tool, 6062A-3. Position Driver, Special Tool 6908-1 with undercut side facing up on top of the tone wheel.






2. Press the tone wheel onto the hub/bearing assembly until it is flush with the end of hub shaft.
3. Install the 4 hub/bearing to axle flange mounting bolts into the 4 mounting holes in the flange of the rear axle.
4. Install the rear brake support plate on the 4 mounting bolts installed in the flange of the rear axle.
5. Align the rear hub/bearing assembly with the 4 mounting bolts and start mounting bolts into hub/ bearing assembly. Tighten the 4 bolts in a criss-cross pattern until the hub/bearing and brake support plate is fully and squarely seated onto flange of rear axle.
6. Tighten the 4 hub/bearing mounting bolts to a torque of 129 Nm (95 ft. lbs.)
7. Install the rear wheel speed sensor on the rear hub/bearing flange. Install the speed sensor attaching bolt and tighten to a torque of 12 Nm (105 inch lbs.).
8. Check the air gap between the face of the wheel speed sensor and the top surface of the tone wheel. Air gap must be less then the maximum allowable tolerance of 1.2 mm (0.047 inch).
9. Install the brake drum onto the rear hub/bearing assembly.
10. Install rear wheel and tire assembly, tighten wheel stud nuts to 129 Nm (95 ft. lbs.).
11. Adjust the rear brakes.
