Crooked front end?

[scraph]

I have no issues with abnormal tire wear, alignment, or ride quality ... I, however, have noticed that the front end (solid front axle on a 2002 F-250 4x4) is crooked ... either that, or it is the fenders. What I mean is that the spacing between the fender and the wheel (as in, the space required to fit a larger diameter tire) is not matched from side to side. Between the front of the fender and the tire it is greater on the driver side than passenger. Between the rear of the tire and the fender, then, it is less on the driver side than passenger. The leaf spring mounts look good, leaf spring bushing look good, and there has been no apparent damage to frame rails from accident or otherwise.

I seem to remember stumbling on a TSB in the past about the sway bars on this truck being undersized, possibly becoming bent ... and I believe the conclusion was it would cause the front axle to twist in this way (but I'm not certain on that).

Any ideas? Thanks!

At some point the leaf springs and axle could have been separated and not lined up perfectly because of a problem with the center bolt alignment. That could cause the problem you're having cause the truck could still be aligned even with the axle housing in there crooked and drive straight without wearing the tires.
