Front Suspension

Hey all:

I have a couple of questions and I will try to describe the situation as clearly as possible.

First. When I am at any speed (it is worse at higher speeds) and I hit a bump (start of a bridge for instance or pothole that has been covered up) my steering wheel vibrates with the suspension. I can feel the steering wheel vibrate up and down. I can not move it while driving (with the latch in the locked position) but when I hit a bump I can feel it "move/vibrate" Is this a product of the stiffer suspension on the R cars or is it a suspension component that I should look into replacing?

Also, whenever I turn at low speeds I can hear a clunk from the front end. Is this something that needs to be replaced?

Has anyone else had these problems? Any assisstance or guidance would be greatly appreciated. Thanks.
