Do you have any play in the steering box? I know you said you adjusted it, but it's still possible. I had adjusted my box, but still had play because it was really old and worn out. Once I swaped it out for a rebuilt box it fixed the problem.

I think ramman4 is refering to the preload on worm gear. Have someone rotate the steering wheel while you watch all of the steering links. If you have a lot of play you can remove some of it by increasing the pre load.

when you had the truck in the shop did they set toe for you?
Sometimes too much toe out will cause some wandering too

Ya never mentioned if the ball joints or tie rods are wore out ? if u don't know check that out . dead tie rods and ball joints will kill the steering . Also do you have drop pit man arm or a steeering block on there ? The steering blocks tend to be kinda nasty on steering ability too .

Try adjusting the steering box. On top of the steering box there is a nut with threaded bolt going in it. I think the nut is a 9/16ths and I'm not sure of the allen head size on the bolt. What I do is start the truck and turn the steering shaft by hand and watch the pitman arm. Look at how soon it responds when you turn the steering shaft. If it has a delayed reaction you need to adjust the box. Loosen the nut without allowing the screw to change postion. What I do is screw the bolt inward 1/4 turn at a time and then retighten the nut. Turn the steering shaft by hand and see if it did any better. Once you got it where you think it's good go for a test drive and see where you are at.

Heres my take. The truck has a 5 inch suspension lift.

One of the biggest mistakes made when lifting a truck with leaf springs is that to make the front driveshaft reach between the axle and t-case, off roaders will rotate the axle pinion upwards with wedge shims. Unfortunately when you do this to a front axle, you're twisting the knuckles and you introduce alot of negative caster.

Negative caster is very bad, it will cause the front to wander uncontrollably. When you brake the truck will pull hard to one side or other, and you'll be fighting the steering wheel on crowned roads. Negative caster can get downright scary.

To correct it, you'll need to pull out the wedge shims, or use a set of wedged shims to introduce positive caster. Of course, you may need to get a longer front driveshaft and the u-joints will operate with more angle, but since the truck is a part time 4x4, you shouldn't worry because you'll likley be in 2wd for most of the time.

In extremes, some off roaders have been known to cut and turn the knuckles to maintain positive caster while having the pinion turned up.

thanks for the insite i did look and the front does have a set of shims on both sides i plan on taking them out and see what happen. it has a trans case drop on it so the angle for the drive shaft still should not be to bad i just hope its long enough it looks close.thanks for the help to every body who replied i will let you know what happens when i can find time to take them out. i think the center pin is broke as well and thats why the leaf creaks and moves the way it does
