The following five (5) key steps are a summary of this bulletin and are REQUIRED in completing a successful wheel alignment service.
1. Verify the vehicle is in an Original Equipment condition for curb weight, tires, wheels, suspension and steering configurations. Vehicles
modified in any of these areas are not covered for wheel alignment warranty.
2. Review the customer concern relative to "Normal Operation" definitions.
3. Verify that vehicle is within the "Mileage Policy" range.
4. Document wheel alignment warranty claims appropriately for labor operations E2000 and E2020.
The following information must be documented or attached to the repair order:
Customer concern in detail
What corrected the customer concern?
If a wheel alignment is performed:
Consult SI for proper specifications.
Document the "Before" AND "After" wheel alignment measurements/settings.
Completed "Wheel Alignment Repair Order Questionnaire" (form attached to this bulletin)
5. Use the proper wheel alignment equipment (preferred with print-out capability), process and the appropriate calibration maintenance schedules.
If it is determined that a wheel alignment is necessary under warranty, use the proper labor code for the repair. E2000 for Steering Wheel
Angle and/or Front Toe set or E2020 for Wheel Alignment Check/Adjust includes Caster, Camber and Toe set (Wheel alignment labor time for
other component repairs is to be charged to the component that causes a wheel alignment operation.).
The following flowchart is to help summarize the information detailed in this bulletin and should be used whenever a wheel alignment is performed.
