Service Procedure
THE WHEEL MUST BE REPLACED IF CODES MATCH ANY OF THE COMBINATIONS OR ARE UNREADABLE/ILLEGIBLE:
1. Remove wheel covers, 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 codes stamped on the center portion of the wheel.
3. Read and record on repair order date code data stamped on center portion of wheel in the following order, (See Figure 1):
A. Manufacturer, Plant and Year Codes.
B. Disc Code.
C. Day code is not to be considered.
4. Repeat above procedure for remaining three (3) wheels on vehicle.
5. As required by inspection, replace necessary wheels (and balance). Use torque stick (J 39544-15) and air gun to tighten lug nuts to appropriate torque. This should be done in two steps using the * (star) pattern. First, snug nuts down by hand. Then, using the * (star) pattern and a torque stick, tighten the wheel nuts to half the final torque. Finally, tighten the wheel nuts to specification using the * (star) pattern and torque stick. Use the same amount of impact wrench time as would normally be used without a torque stick.
6. Render all removed wheels unusable and scrap as required by Corporate Policy & Procedures.
7. Install a Campaign Identification Label.
