Sounds like you need to get it aligned.

Best swap would be crossover steering.

plus a 3+ inch lift if you don't already have it.

and a steering box from an IFS truck.

 

Here's some reading for you

The steering box you'll need is from pretty much any 86-95 4x4 toyota 4Runner or pickup truck. The reason it's needed for crossover steering is the direction that the pitman arm swings (left to right) and not front to back like the steering box you have now.
