Vibration coming from the rear...?
Hey guys, I'm having some issues with the vibrating of the car at certain speeds. I initially thought that the wheels were not balanced correctly but recently I got new tires and wheels and had them balanced and now the problem has gotten worse. Now my steering angle is all weird too!
It vibrates the car between 37-39mph which doesn't bother me much but anything over 70mph is horrendous. It almost feels like the car is shaking as a whole rather than one point creating a vibration... any suggestions on what could be wrong? Thanks.
***UPDATE 02/21***
The alignment is complete and everything is now within spec (thanks Wade! ) but the vibration has not gone away. I'm hoping that there isn't something seriously wrong, but I guess I have expect the worse. Could it be the axle? Transmission/motor mount? Hub? Rotors..??
...got another problem.
When I installed my new wheels (w/ the stock suspension), I noticed that the steering wheel angle was thrown off. I figured I somehow threw off the alignment when I changed out the wheels. After the alignment though, it seems that the steering wheel angle is still off. I also noticed that the new tires howl like something is not rolling straight either. Could this be a tire issue or could something be really off on the car itself?
***UPDATE 02/21 - 2***
Just got back from changing out the front tires to the old ones to see if it was the tires... steering angle is still whack, and the howling sound is coming from the 225/45 tires rubbing against the fender liner - even before it was lowered it was making the sound. Needs higher offset wheels in the front w/ 225/45.
I've also found some alike topics:
this one describes it perfectly:

Any help/input would be much appreciated!

A print out of the alignment would help. Try jacking the car uP on all four corners and turn the car on an put it in gear. While the tires spin, look to see if anything looks suspicious. Something may be bent or warped. Also, take a look at your drive shaft to make sure it's not bent. have the car running for this as well.

It's definitely in the seat and not in the steering wheel~
It's harder to tell at the lower speed shakes, but in the high speed shakes, no, it does not go away until i drop speed below 68mph.
