ok this is for my daily adriver which is a 93 biuck skylark custom(3.3L, cold air intake, 8mm racing wires, split fire spark plugs, and ported intake manifold) anyway the car vibrates really bad around 60, and in corners, i had a aliment done, so it cant be that, i was thinking a bad tie rod end???
not really sure, yes i know its not a seven, but i figured some one can help me.

to test the tie rod end, jack up the car and try shaking the tire/wheel. If it's bad, then there will be some movement.
I have a bad one right now. The wheel moves a little and I get a LITTLE clank noise when I do it.

 

check your tires althought you had an alignment that doesnt mean that while out of alignment your tires didnt wear unevenly this kind of problemused to happen to my lumina and i switched tires and it stopped

 

cool thanks guys

also check the play in the steering rack. Long shot, but you never know

 

haha turned out to be loose lug nuts for me, that was scary

 

hmm, my mom drives a skylark and i swear her car spits off its lug nuts...have to replace one every once in awhile. its weird.

 

My explorer does that vibe thing between 60 and 65mph. It has a loose U-joint in the front axle.
