I really didn't check them. But from my experince as a MB tech I never replaced Rear Sway Bar bushings. Just trialing arms and links. All those look ok. Im thinking hey maybe something is broken,but wouldn't I hear something. I just see my new pilots outside edges being slowing cut into like a sardine can. Hmm lets see ah $300.00 a piece. I going to have my front end man drive it see what he thinks. Keep asking some of your buddies.
