I have a recently purchased 1990 F250 4WD Diesel. As far as I can tell there is no frame damage , but when I installed oversize tires I noticed that the axles seem to be furthur out in the wheel wells on the right side of the truck. As I mentioned, there is no visible frame damage but I cannot think of anything else it might be. ANy ideas? Could there be worn bushings or something mounting the cab and bed?

 

This could be tough...first, this is the easy part put the tires from the right side on the left and the left on the right....if the right is still out further you have eliminated the possiblility of having off center wheels. Next (if this is not the case) Go to your local used car lot with a similar truck and take some measurements, I would measure spring shackle to dust cover all four sides, measure front axle to rear, one side then then the other.: P.S. the front axel is supposed to be slightly wider than the rear for handeling characteristics, and improved payload.

good luck hope this helps to give you an Idea,,,

 

 

Hi, My truck is the same way and an old ford mechanic told me that someone probably put an f-350 hub and rotor on the one side he says they fit right on but the wheel sticks out further on that side. John (fatforty)
