Rear tires/axle misaligned -- a congenital defect or poor bodywork?

[Grant Eaton]

This past weekend I had four Toyo Proxes S/T 285/60/R18 slapped on the stock rims. These larger tires made plainly obvious an alignment problem on the vehicle -- the rear axle appears to be offset to the right about 2" (using the cladding as a reference point). Has anyone else observed this problem? Any idea as to whether it can be fixed?

The guy at Les Schwab Tires told me that this type of problem is "common for certain models of cars." He cited his own GM Capri (or something like that), saying that most of that model's cars get their axles/tires shifted off normal alignment within 2 years.

My VX was in a very bad $13,000 driver-side T-bone crash about 3 years ago, so it's possible that the bodyshop didn't do a good job and that this problem I noticed was actually stemming from imperfect bodywork. Would some of you folks mind checking your vehicles to see if this problem is congenital from the factory?

EDIT: My VX isn't lifted... Also, I have not adjusted the torsion, although I intend to do so this week to raise it at least 1" inch to accommodate the larger tires.
