To be honest, this isn't anything new. What I'm getting is a vibration, felt through the steering wheel and throttle pedal (actually, pronany everything that's solid on the ar if I went and touched it). Also, at least on the freeway, the ride feels uncomfortable for what I would expect from a Benz; I can feel every bump and whatnot. My mom's Pontiac rides better.

I had been blaming this on the bad upper control arm bushings, but replacing them doesn't seem to have made much of a difference. The tires were balanced recently, and I think I need an alignment.
I'm thinking that either the alignment issues that I probably have are causing it, or that I may have bad shocks (I was almost certain the shocks were bad until I did the "push test" on another vehicle that supposedly has almost new shocks and it reacted the same way). Anything else I can check? This isn't critical; just an annoyance...
Thanks in advance!
