Owner Letter

Dear GMC Truck Owner:

Some time ago you expressed your confidence in GMC Truck Division through the purchase of one of our GMC Sierra pickup trucks. We appreciate that decision and would like to advise you of a special policy covering the front suspension of your vehicle - specifically, the maintenance-free ball joints and the front wheel alignment procedure.

Your full size GMC pickup truck incorporates maintenance-free front suspension ball joints and a front suspension feature designed to improve the vehicle's ability to maintain front wheel caster/camber alignment. These changes were made in the interest of improving your satisfaction with our product by reducing the amount of required maintenance. We have found that in some cases, however, the actual vehicle maintenance required may not have been reduced.

Ball Joints:
The maintenance-free front suspension ball joints in some of these trucks have experienced contamination. Because of this, we have changed the design of our current production ball joint to a greaseable style ball joint. A contaminated ball joint can cause squeaking while turning and/or more frequent steering input while driving down the road. Contamination could cause a ball joint to wear out and eventually to separate. If any sign of contamination should occur in your vehicle, please have it repaired at your GMC Truck dealer.

Should ball joint contamination cause this condition in your vehicle within 5 years or 100,000 miles of vehicle purchase, whichever occurs first, the maintenance free ball joints will be replaced with greaseable style ball joints free of charge. Greaseable style ball joints should be lubricated at the same interval as the other chassis lubrication fittings on your vehicle. Vehicles requiring ball joint replacement do not necessarily require front wheel alignment. If you have had the ball joints replaced on your vehicle prior to receiving this letter, you can obtain reimbursement for any parts and/or labor charges you may have incurred by providing your dealer with the original paid receipt prior to March 1, 1991. This offer does not apply if the replacement was due to collision damage.

Front Wheel Caster/Camber Alignment Parts Kit:
The front wheel alignment set by the assembly plant will not change and should not need adjustment except in cases where accident or road hazard damage has occurred. Previously, if caster/camber alignment was performed at your expense, you were also charged for the required alignment parts kit. Due to the cost of the parts kit, the charge for a wheel alignment would not be competitive in today's market place. In view of this, GMC Truck has issued a special policy to cover the cost of the caster/camber alignment parts kit but not the installation cost. This kit is included in vehicles currently being produced.

In the event your vehicle requires a caster/camber alignment in the first 5 years or 100,000 miles, whichever occurs first, your GMC Truck dealer will not charge you for the cost of the required parts kit. If you have paid for a caster/camber alignment performed on your vehicle prior to receiving this letter, you can obtain reimbursement for the cost of the parts kit, but not the labor to install it, by providing your dealer with the original paid receipt prior to March 1, 1991.

We are sorry if either of these conditions have caused you any inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.
