Diagnostic Procedure # 1 - Tire Mismatch

Compare the installed tires and wheels to the certification label. If the tires and wheels match, continue with the diagnostic procedure.


^ IF THE TIRES AND WHEELS DO NOT MATCH THE CERTIFICATION LABEL, compare tires and wheels to RPO (regular production option) list and set tire psi to the correct value and continue with the diagnostic procedure.

^ IF THE TIRES AND WHEELS DO NOT MATCH THE CERTIFICATION LABEL OR RPO AVAILABILITY, swap known good tires and wheels (as called for by the certification label or RPO list) for the purposes of evaluation only.

Set tire pressure to value on the certification label.

1. Spin the front tires to be sure that the front hubs are unlocked. If hubs are unlocked, the axle shaft will not rotate with the wheels (4x4 models only).

2. Tire Pull - Swap the front tires from side to side and road test. If the concern is not corrected, continue with next step.

3. Tire Pull - Swap rear tires from side to side and road test. If the concern is not corrected, continue with next step.

4. Tire Pull - Swap front tires from front to rear. Set the tire pressure to the required pressure for the new front and rear positions, then road test.

NOTE: ON REAR LIMITED SLIP AXLE (FRONT HUBS UNLOCKED) DRIFT CONCERNS, IT MAY BE NECESSARY TO MEASURE TIRE CIRCUMFERENCE AND PLACE A MATCHED SET OF TIRES ON THE REAR AXLE.
