Service Procedure

REINSPECTION

IMPORTANT:
REINSPECTION MAY BE ACCOMPLISHED BY REVIEWING THE PREVIOUS CAMPAIGN 90-C-13 REPAIR ORDER IF THE WHEEL CODES WERE NOTED ON THE REPAIR ORDER. IF REPAIR ORDER REVIEW INDICATES EXPANDED CODES ARE STILL NOT INVOLVED, NOTIFY CUSTOMER AND IF VEHICLE IS AT DEALERSHIP, PROCEED TO STEP 7 AND INSTALL CAMPAIGN IDENTIFICATION LABEL.

OR

REINSPECT ALL WHEEL LOCATIONS ON THE VEHICLE.

1. Remove wheel cover, using care to avoid damage to cover and wheel surfaces.

2. Thoroughly clean outer surface of wheel using appropriate cleaning materials and tools.

NOTICE:
WHEEL MUST BE CLEANED TO ASSURE CORRECT READING AND INTERPRETATION OF DATE CODE STAMPED ON THE CENTER PORTION OF WHEEL.





3. Read and record on repair order date code stamped on center portion of wheel in the following order (see figure):

A. Manufacturer, in plant and year codes.

B. Disc code

C. Day code is not to be considered.





If codes match any of the combinations on list or are unreadable/illegible, the wheel must be replaced.

4. Repeat above procedure for remaining three wheels on vehicle.

REPLACEMENT

5. As required by inspection, replace necessary wheels (& balance). Use torque stick J39544-15 and impact gun to tighten lug nuts to appropriate torque.

This should be done in two steps using the star pattern. First, sung the nuts down by hand. Then using the star pattern and a torque stick or torque wrench, tighten the wheel nuts to about half the final torque. Finally, tighten the wheel nuts to specification using the star pattern and the torque stick/wrench. Use the same amount of impact wrench operating time as would normally be used without a torque stick.

6. Render all removed wheels unusable and scrap as required by Corporate Policy and Procedures.

7. Install Campaign Identification Label.
