The front thrust rod bushings—also referred to as tension strut bushings—are known to fail occasionally. The oil-filled rubber mounts weaken and crack over time, causing a mushy road feel and shuddering in the steering wheel when going over bumps.Google+

I went to firestone and had the vehicle inspected. They said that the bushings were loose so I guess I need to replace them when I can. At around 40 to 50 mph the steering wheel shakes a lot, especially when going over bumps.

At 45 MPH tires start to wobble....goes away at 50 MPH. BMW says to replace the thrust bushung and get new tires/ alignment.
