Tools Required

J 8001 Dial Indicator Set, or equivalent

1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle .
2. Mark the location of the wheels to the wheel studs and mark the specific vehicle position on each tire and wheel - LF, LR, RF, RR.
3. Remove the tire and wheel assemblies from the vehicle. Refer to Tire and Wheel Removal and Installation .
4. Remove the brake rotors and/or brake drums from the vehicle. Clean the mounting surfaces of the brake rotors, the brake drums, if equipped, and the hub/axle flanges of any loose debris, rust, and corrosion. Refer to the following procedures:

•	Front Brake Rotor Replacement

•	Rear Brake Rotor Replacement , if equipped.




5. Position the J 8001 , or equivalent, on the machined surface of the wheel hub/axle flange outside of the wheel studs.
6. Rotate the hub one complete revolution in order to find the low spot.
7. Set the J 8001 , or equivalent, to zero at the low spot.
8. Rotate the hub one more complete revolution and measure the total amount of wheel hub/axle flange runout.

Specification - Guideline
Wheel hub/axle flange runout tolerance guideline: 0.132 mm (0.005 in)

9. If the runout of the wheel hub/axle flange IS within specification, proceed to step 12.
10. If the runout of the wheel hub/axle flange is marginal, the wheel hub may or may not be the source of the disturbance.
11. If the runout of the wheel hub/axle flange is excessive, replace the wheel hub/axle flange. Measure the runout of the new wheel hub/axle flange. Refer to the appropriate procedure:

•	Front Wheel Bearing and Hub Replacement

•	Rear Wheel Bearing and Hub Replacement




12. Position the J 8001 , or equivalent, in order to contact the wheel mounting studs.

Measure the stud runout as close to the flange as possible.

13. Turn the hub one complete revolution to register on each of the wheel studs.
14. Zero the J 8001 , or equivalent, on the lowest stud.
15. Rotate the hub one more complete revolution and measure the total amount of wheel stud - stud circle - runout.

Specification - Guideline
Wheel stud runout tolerance guideline: 0.254 mm (0.010 in)

16. If the runout of the wheel studs - stud circle - is marginal, the wheel studs may or may not be contributing to the disturbance.
17. If the runout of the wheel studs - stud circle - is excessive, replace the wheel studs as necessary. Measure the runout of the new wheel studs. Refer to the appropriate procedure:

•	Wheel Stud Replacement

•	Wheel Stud Replacement
