Service VME - Hard Plastic Rear Axle Boot Protectors

When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.

The new GMC Sierra Denali pickup truck comes standard with the QUADRASTEER™( NYS ) all wheel drive steering system. In an effort to protect the steering components, effective with trucks built on and after March 25,2002, we have added a black hard plastic boot cover to the steering linkage on the rear axle. Dealers should not attempt to remove this cover as it is intended to remain on the axle.

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance. This diagnostic approach was developed for the vehicle with the VIN you entered and should not be automatically be used for other vehicles with similar symptoms.
