SUBJECT:
Vehicle Vibration


MODELS:

1990-92 (BD) Talon
(B2) Summit

SYMPTOM/CONDITION:


Vehicle exhibits a vibration that can't be eliminated with normal tire and wheel balancing. The vibration may be caused by wheel runout. New wheel runout specifications (both radial and lateral) have been established.


REPAIR PROCEDURE:

This repair procedure involves measuring wheel runout.

1. Mark the wheel stud closest to the tire valve stem for future reference.

2. Remove the wheel and tire assembly from the vehicle.

3. Adjust the wheel bearings and check the wheel mounting surface for runout.

4. Remove the tire from the wheel and remount the wheel on the vehicle in the same stud position outlined in Step 1.

5. Tighten the lug nuts to the specified torque outined in the appropriate service manual.








6. Using a dial indicator, check wheel runout as shown in Figure 1. Refer to Figure 2 for REVISED Wheel Runout specifications.


7. If wheel is out of specification, rotate the wheel 180 Degrees on the hub and check runout.

8. If the wheel still exceeds the limits in, replace the wheel.

9. If the wheel runout is now in specification, mark the stud nearest the valve stem and erase the original mark made in Step 1.

10. Install the tire on the wheel and balance the assembly on an off-the-car dynamic balancer.


11. Install the wheel and tire assembly on the vehicle (located on the stud with new mark made in Step 9.) and tighten to the specified torque.

12. Verify the condition is eliminated.


POLICY: Reimbursable within the provisions of the warranty.
