My Ford F350 had some handling issues. Basically, it had a mind of its own, meaning on a straight smooth road it liked to wonder where constant corrections was needed. This was not fixed by the standard alignment, or changing tire presures etc.
The internet is a swell tool. I just had to Google this problem and I came up with this fine site:

http://www.d26.net/240sx/mirrors/Whiteline_WheelAlignmentTermsAndTheory.htmApparently this wondering issue is addressed by checking the wheel caster alignment.
So I did what was suggested and had the alignment shop change my caster from 0 (zero) to 5 degrees.
In one word; "Amazing". I would suggest to anyone who is not satisfied with their Fords handling ability to do the same. This sure beats throwing money at suspension improvments and then finding the problem still exist.
I then went one step further.. My stearing seemed to be tight. (Ford already changed out the stearing gear box). With the suggestion from my brother, who works at Ford, I disconnected the stearing stablizer. Now the stearing preasure is more normal. Alignment shop say to just remove
it, and I did.
Just thought I would pass this info on to any who may have the same problems.
