| Gents,
On the rear of the e36 there are no ball joints. The hub fits directly to the trailing arm. This trailing arm attaches to the body with a bushing (RTAB). The lower control arm attached again with bushings (at the arm & at the subframe). The upper control arm (which houses the spring) again connects with bushings at the hub/trailing arm & the body.
If you look at the bushings and they're not cracked, falling apart, or the metal has seperated from the rubber material they are likely okay.
So how do the RSM's look? Increased damping shocks (Koni, Bilstein, Tokico etc.) put increased load on the RSMs. It could be that the ones you used weren't up to the task.
Have you investigated the other areas?
