sounds like something with the front angles, to be exact my guess would be pinion angle too low, do u have the right length control arms?

if your uppers are adjustable they could be adjusted wrong and causing the a caster issue which would angle your front pinion too far up or too far down, not sure on an exact number as far as degrees goes other than eyeball it, not sure how to explain it but give this a read if you try to adjust it http://pirate4x4.com/tech/billavista/PR-shaft/index2.html
