Re: 99 Cadillac DeVille d'Elegance Stabilizer Bar repair help!?!?
My service stability control light came on two days after i noticed a klinking sound. When i got under the car, the bar was broken, out of its place and dragging on the ground. Its the piece that goes into the engine, not the links.
Sounds like he's identified it correctly. Broken sway bar is far from unheard of. It's yet another one of those 'late model' '80's-early 2000's GM idiosyncrasies. A little more common on the W-body than others. Rust + hollow bar = breakage.
Dorman makes a lot of replacements. You might find one by them. If not, you'll probably need to resort to the dealer or a salvage part.
