Right rear clunk and rear end swerve when hitting bumps.

I have a 95 325i and when I first go in reverse I hear 2 clunks coming from the right rear it sounds like its coming from right around the wheel it also happens sometimes when I first take off but only once not twice. The second problem I'm having is when I hit decent sized bumps the rear end feels like it swerves to whatever side the bump is on and pretty seriously not just a minor little pull its more like a jerk. Any help or suggestions would be greatly appreciated.

You probably need new rear shock mounts and trailing arm bushings.

I'm betting shock mounts. You can look from under the rear where the shock attaches to the subframe. Check for cracks, tears etc. Also check for cracks around the subframe. You should also pull the carpet from around the shock tower in the trunk and check the condition of the top of the mount. When you replace the mounts don't forget to use shock mount reinforcement plates.

^+1. Also, simply having blown shocks can cause the car to step out of line over bumps.

As far as the clunks go, I'd check your differential mounting points. Basically just get under the car and look for broken parts & bushings.

I'm wondering what kind of RTABs were used as replacements? If cheap aftermarket they could have also failed in addition to the mounts.

I was thinking that is possible because it sounds like an rtab but the shocks are good and as for the bushings I think at least 2 or 3 in the right rear/middle of the rear appear to be bad but im not sure exactly what any of them are I'm not very mechanically inclined.

I think you are referring to the Rear differential bushings. You can buy a really good rear suspension refresh kit from ECS Tuning.

I think that's what they are but I'm definitely not sure and I would like to go through and replace all the rear bushings myself but I'm not sure if I could do it because im really not sure how difficult it is.

It isn't easy if you aren't mechanically inclined. You have to remove the exhaust, then drop differential and sub-frame. And when you get to that point, you need a hydraulic press to remove & install the bushings.

Agreed, to replace the diff bushings is a beast of a job. I am going to do rear shocks, mounts and RTAbs and see how it handles before I tackle the diff bushings.
