I am trying to get my truck to drive a little nicer.

The 18" wide tires are probrably most of the problem, but my front pinion is about 10*

Does that screw up all the caster and such? My "C's" are straight up and down, so maybe someone turned them?

It kinda bounces around the road learching a foot left or right at times, and i have a rock ram installed which should dampen things down a bit.

Should i turn the pinion back down?
