On a 1992 F 250 4x4, is it possible to adjust the cambers on the front axle, on my truck the front right tire wears on the outside edge. I know the ball joints are good. Is this something that a professional has to do. What does it take to make the adjustment and know if it is right.

 

There is a bushing that surrounds the top ball joint. Changing the bushing is how you adjust camber.

The factory offers bushings in 2 degree increments.

Superlift offers one bushing that is adjustable. When you have a wheel alignment done, they can tell you what the camber is.

 

It's something you should have an alignment machine to do. Bushings are available to adjust camber and caster at the same time, both of which can cause pulling to one side. Plus anytime an adjustment is made, toe will have to be readjusted, which is a major tire wear angle.
