Caster setting

To start with I have used the search feature, and found that to help with return to center caster should be increased. Does anybody have a number it should be set to? Mine is currently set at 1.5 degrees positive according to the printout I was given after my alignment. 1 to 3 degrees is spec, according to the printout. I am looking for a number to tell the alignment guy to set it to and I guess ignore the spec.

FoMoCo thinks too much caster angle makes/contributes to the "death wobble", so...A TSB had the tech take out some on my truck when I had the wobble problem. Maybe there is a problem, not an adjustment, that is causing your return to center concern?

I have around 3.5* caster with a Pure Performance track bar, and mine drives absolutely fine. No death wobble since the new track bar went in.

According to the alignment shop, the ball joints, tie rods, etc. are all good. I jacked up the wheels myself and can't find any play in anything. It just doesn't want to return to center after a turn.

Increased caster helps with the return to center feel so I would have it set to 3+ degrees.
