So i have a 1990 fox body mustang gt and i have this horrible vibration. At about 50 mph the car inst bad you can feel it just barely. But 60+ it is horrible the gear shifter is vibrating like crazy and the steering wheel just started to shake up and down and kinda all over the place. I know about the aluminum drive shaft and i plan on buying one but why does the steering wheel shake so violently like that? Also i dont know if my car has any aftermarket springs in it but i know it has aftermarket shocks in it but some reason now its sitting at least an inch or 2 lower in the back than the front and when i go over a speed bump it clunks in the back what will fix this?

Thanks

1: Get under the car and inspect the suspension. If you're suddenly sitting two inches lower in the rear for no apparent reason, you need to take a look at what's going on under there now.

2: See step 1.
