Possible to have off-center rear axle?

[Prime Lord]

So I got these new 245/45/17 for the rear. I like em. The front meats almost need replacing. I was thinking about getting some 275's for the rear and swap the existing 245's up front. The only thing keeping me from going this route is the rear axle. The drivers side tire sticks out further than the passenger side, and the existing 245 hits the fender sometimes when I go over large bumps or dips in the road. What could cause that? I've got MM LCA's installed, so I know the lowers aren't bent or something. Torque boxes? I crawled under there today and nothing looks bent or broken. I have yet to get it off the ground and take a closer look, but I'm curious as to what to look for.

has the car ever been hit in the rear, even a little bit? if so it could be just enough to tweak the frame a bit. Not sure what else it could be. The backspacing on the rims is obviously the same right?

 

[Prime Lord]

its never been hit to my knowledge. And yeah, the rims are all 17x8 99 Cobra wheels. The rear disc brakes are off of a 96 6'cyl rear end. Axles, brackets, etc. The axle tube and dif are the original on the car.

It's not uncommon (even when on new, untweaked Stangs). Locating the rear-end laterally can help this situation.

 

[Prime Lord]

is that something a frame shop has to do or can I do it myself?

Adding a panhard bar (for instance) can help a lot. Check out Maximum Motorsports, Griggs and other suspension-oriented sites for info and products.

Most of the Stangs I've looked at close enough to check it out have had rear ends that were slightly off center.
