I need help! Previously wrecked car!

Ok, Heres the deal, The previous owner of my car ran into a ditch and parked the car in his barn for 3 years, I got it, put a new fender and nose on it and got it running good.The suspension underneath looks very straight but the passenger strut tower is pushed over and back a little bit...My passenger wheel is back about 1 1/2 inches from the driver side, I am guessing this is because of the stut tower...I also have a very extreme vibration once I get up to speed, Any ideas if that is the problem or what else could be wrong!? Thanks

Are you asking for someone to inspect the frame geometry over the Internet?

Actauly I was asking if a pushed back strut tower would cause those problems or if there is anything else in particular that would cause those problems...As in something particuar I could go and check. Thanks!

Definitely. If the front wheel is pushed back like you describe, it's probably toed in or out considerably as well as the caster angle is now way off. The caster will really show up as you steer the wheel off center, the toe in/out will be full time but get worse as you increase vehicle speed.

Next stop for you is a body shop with a frame puller. They may be able to straighten it back out.

But like I sais the suspension and frame from underneath look really good, Prefectly straight...Only noticle obervation is the stut tower back.

I'd swap out the a-arm and see what that does. The a-arm is the piece that really locates the wheel, not the strut. You might also have a bent k-member. If this is all you have wrong, it won't be a bad fix. Your best bet is to take it to a body shop and let them put it on the frame machine.
