The 2004 Silverado 1500 continued to give problems. I had the speedometer cluster replaced recently to resolve that issue, but the vehicle shimmied and bounced as it went down the highway. I knew it was the vehicle because I didn't have this experience on my other cars on the same highway.

: the contact stated the vehicle will not align properly. The improper alignment resulted in premature tire wear on the outside of the tires. The problem manifests itself with the right front tire showing excessive outside wear and eventually affects every tire. The vehicle has been maintained with proper tire rotation and is only driven on the highway. The front end has been aligned three times by the service dealer without getting a proper alignment. Also, with every alignment attempt the tires were replaced. The dealer contacted the manufacturer who determined this was a normal characteristic of the vehicle, although the vehicle has dual wheels.

I am an automobile mechanic and have been for over twenty years. On 9\17\04 I purchased a brand new 04 Chevrolet Silverado super sport, a truck that the GM factory lowered two inches in the front and four inches in the rear. The first night I owned the truck I noticed a series suspension problem. On Monday I looked under the front suspension and realized the factory lowered the front end right down on the bump stops, so it has no front suspension. I took the truck back to the dealer and told them the problem they said, oh yea there all like that. I was driving home on 9\26\04 doing 70 mph on the freeway and hit a little tiny bump in the road and almost lost control of the truck. When I hit a bump the front tires come off the ground. This truck is very unsafe I can go over even the smallest bump and feel the front end come off the ground. This truck is a very limited edition. I emailed GM and asked them if it would be ok to lower my truck down on to the bump stops they told me that would not be recommended for safety reasons! so I ask you why did there factory do it if they know it is unsafe. One last thing this truck is very hard to stop it dozen`T transfer weight when braking. It sure is a pretty truck though just not safe.

The consumer stated that the sway bar mounting bracket broke, causing the frame and mounting bar to come off. The consumer had the vehicle towed to the dealer, and it was repaired under warranty. The front sway bar mountain bracket broke off at the weld and caused abnormal "roll" control and hard steering.
