Front Suspension Stabilizer Bar problems of the 2009 Chevrolet Traverse

My wife and I own a 09 chevy Traverse and have had for about 3 years. When we first bought it it drove like brand new but over the period of a year or so we started to feel a side to side swaying (such as rocking in a boat) while driving about 60 mph. Since we've got 4 kids and my wife uses it as a day to day vehicle I took it to the dealership and had them tell me it was struts (which I had replaced) and after being replaced it still had the side to side movement. It has gotten to the point I don't allow her to drive her nor the kids because of the dangers. I've had the rack n steering, front upper and lower control arms the rear upper control arms, stabilizer bar bushings along with numerous other bushings and all 4 brand new tires. The dealership nor other independent shop knows what else to replace.

Tl-the contact owns a 2009 Chevrolet Traverse. The contact stated while parked, and attempted to backup vehicle, there was a piece of metal that fell of vehicle. The contact saw the stabilizer link bracket on the stabilizer bar of the front driver side, was hanging loose. The vehicle was taken to a dealer, however no assistance was provided. The vehicle was also taken to a repair shop, where they determined the bracket had not been welded properly, and was repaired. The bracket was welded again to strap and replaced by a new stabilizer link. The manufacturer was made aware however no assistance was provided. The current and failure mileage was 81,000. Yn.
