2002, f150 SCREW FX-4. I just got my truck out of Sears Service for a front end alignment. The wheels have negative camber. (Top of tires inboard) Not much, but I surely don't like it.

The spec page shows all adjustments are within recommended specs.
The question is...which of the cam bolts controls the camber? Front, rear, or both? I might just take a poke at this myself before taking it back in to Sears.

I just finished installing a 6" fabtech, all tie rods, pitman arm, idler arm, all ball joints. (Upper control arms) The front end is tight.

 

Both cam bolts control camber and caster at the same time. If you adjust one bolt, it will affect both measurements. Keep in mind, that if you adjust either one of those bolts, you will have to reset your toe.

This doesn't sound like I should be poking around moving cam bolts does it?
Think I should take it back and tell the alignment tech I don't want negative camber?

 

No, you really dont want to mess with the adjustments without an alignment machine. When I did my align, I set the caster about 1/2 degree higher than stock to push the wheels toward the front of the truck. I set my camber at about .1 to .2 degree positive, and I set my toe at .05 degree positive. These measurements, in my opinion, are most ideal. Excellent steering geometry, st. wheel returnability, compensation for road crown, & minimal tire wear.
