I have a 06 wrx sti. Whenever I am at low speeds hitting a bump or turning my car makes a thumping noise in the back. I can't tell which side it's on. My sway bar links were snapped in the rear I replaced both of them and it didnt fix my problem.
The more weight I have in the back the more it happens. If I let the car sit for a week it won't happen right away for a couple hours.*
Anyone have a similar problem? Or a idea of what it is?
