NOTE
Before servicing the vehicle, also refer to the precautions in the beginning of this section.

Inspection



Tone wheels can cause erratic wheel speed sensor signals. Inspect tone wheels for the following possible causes.



missing, chipped, or broken teeth
 
contact with the wheel speed sensor
 
wheel speed sensor to tone wheel alignment
 
wheel speed sensor to tone wheel clearance
 
excessive tone wheel runout
 
tone wheel loose on its mounting surface
 

If a front tone wheel is found to need replacement, the halfshaft must be replaced. No attempt should be made to replace just the tone wheel.

If a rear tone wheel is found to need replacement, the tone wheel is incorporated into the hub and bearing assembly and the hub and bearing must be replaced.

If wheel speed sensor to tone wheel contact is evident, determine the cause and correct it before replacing the wheel speed sensor or tone wheel.

Check the gap between the speed sensor head and the tone wheel to ensure it is within specifications:

1999-00 Wheel Speed Sensor to Tone Wheel Clearance



Front Sensor: 0.007-0.072 inch (0.17-1.80mm)
 
Rear Sensor: 0.015-0.059 inch (0.37- 1.50mm)
 

2001-05 Wheel Speed Sensor to Tone Wheel Clearance



Front Sensor: 0.017-0.067 inch. (0.42-1.71mm)
 
Rear Sensor: 0.015-0.052 inch (0.38- 1.31mm)
 

Excessive tone wheel run-out can cause erratic wheel speed sensor signals. Maximum allowable tone wheel run-out:



front tone wheel maximum run-out: 0.009 inch (0.25mm)
 
rear tone wheel maximum run-out: 0.009 inch (0.25mm)
 

If tone wheel run-out is excessive, determine if it is caused by a defect in the halfshaft assembly or hub and bearing. Replace as necessary.

Tone wheels are pressed onto their mounting surfaces and should not rotate independently from the mounting surface. Replacement of the front halfshaft or rear hub and bearing is necessary.

Removal & Installation



The tone ring (toothed wheel) is not separately serviceable. If any of the teeth are deformed, replace the driveshaft assembly (front) or the brake rotor (rear).
