Three problems related to rear suspension have been reported for the 1999 GMC Suburban. The most recently reported issues are listed below.
Whenever making any turns, right or left vehicle's rear end would sway, dangerously. Vehicle was not stable.
I have tried to resolve this with san bernadino GMC and inland valley GMC. No satisfaction yet. Brakes go out on an average of 5000-6000 miles. Now, GMC will not warranty them any longer because of my problems. Steering wheel noise has got better but not fixed yet. Had this since I have had the vehicle. Vibrating in rear end, occures after warm. Continouse problem.
Fuel pump has been replaced two times due to loud noises. Also, transmission was replaced because it did not shift gears automatically, rough switch. Abs brakes did not operate properly, causing extended stopping distance. In addition, two tires replaced in the rear due to vibration of vehicle. Dealer contacted, and are attempting to remedy the problems that exist. Provide further information.
