Nissan Repair: suspension, tie rod ends, suspension geometry

Question
I have a 94 nissan truck with a 4in body lift & a 3in susp lift 37in tires I have a problem after taking it off road the front tires are turning in towards each other we adjusted the tie rods and alined the tires back but when you lock in 4wd the tires pull back in what can cause this?

Answer
Kelli,

Suspension geometry has changed as a result of the lift and I bet the store did not sell you all the parts you need.  The rack is probably going to have to be lowered so the toe does not change under jounce and rebound.  That is, when the truck bounces up and down.  The rack or the tie rod ends are going to have to be at the same height to compensate for the lift.
