Hey, digging this thread back up, to update if you have odd tire wear, or pulling to left/right, check/replace your upper kingpin bushings. Not knowing the status of mine, I went ahead and replaced both sides on both trucks.
3 out of the 4, the nylon bushing was broken into pieces. I was seeing inner tire wear on both, so figured it couldn't hurt to start here. While you're there, check bearing preload, too. I had 2 with some play, so readjusted those. Now both drive normal. Need to run by and check alignment, just to be sure everything is within spec.

Picked them up from here:

I have 419,000 miles on mine currently, and I have never rebuilt king pins. Several sets of king bushings have been replaced, however. You can't get them at most Off-Road truck shops. (or they usually know where to get them)

 

What was the verdict? Looks more like you have a toe out situation to me.

 

A friend noticed uneven tire wear on my dually this weekend!!!!!!!! When I checked; the inner half of both tires were worn bald, not sure how I didn't notice. Brand new tires with less that 7k on them.

I took it in today and mine was out of aligment by 11/16th.............to get my safety I had to replace the front rotors so I'm assuming them idiots didn't perform an alignment. So will be visting them with my work order and will be raising some hell.

The shop today said the kingpins were fine; hope they're right.

 

no i got those king pin bushings from Randy's King and pinion and put them in and haven't had problems with tire wear since. So i think that was the problem. It was a cheap and easy fix.

 

alright, digging this back up because my tires are getting that funny wear in the front again. Its only worn on the inside of the tire and it cups them funny. I changed the king pin bushings a while ago and it seemed to help for a while and now its doing it again???

My steering will bind or stick once in a while and I just have to give it a jerk and then other times it is just fine. I am starting to suspect my front u joints sticking??? could this cause this odd wear? I know I need to replace them but wouldn't think it would wear the tires like this.

 

Going down the road, does the truck want to "follow" dips and crevices? Meaning, those little black lines where they patched the road with tar are slightly lower and the tire wants to follow it.

Clear as mud???

 

not exactly, this happens when I turn. sometimes when i turn it will bind or stick so i jerk the wheel and bring it back then it will try and stick the other way and sometimes make a slight pop. It only does this sometimes but it seems that when this happens it starts to wear on the tires more just by looking at the tires after I stop. Then other times it will drive straight and normal, til I turn again.

 

Maybe lower king pins? There is a set of bearings down there, I could see if they wore out or got contaminated that it would cause steering issues.

It'd probably be pretty easy to determine, though. Jack the truck up, pull the tie rod and drag link off the knuckle and see if you can turn the hub back and forth smoothly.

 

My guess is you have an outer axle joint sticking causing the bind/pop in the steering, ALSO prob a worn tie rod end which is causing the toe to go out when that joint binds

 

What would cause that?

 

the king pin bushings and tie rod ends are pretty new, and the king pins felt very tight last time I checked. I'm suspecting the front U-joints. For bein the factory non greasable and 251,000 miles on them and been in "lock" half their life, I'm sure they are due for a change. I know they are a little sloppy, just been too lazy to tear it all apart. I could see how they could turn just enough to bind the steering til they turn a little more, but its weird they are wearing the tires like this (unless its just pulling them one way or another)

these tires are about done anyways so I'm thinkin I'll get fix it before I get new ones, or wait for one of my truck pulls to snap them.

 

Bad toe-out or camber. Has happened on a couple CARS that I owned.

 

If yo h ave a steering stabilizer, check to make sure it didnt rotate any causing it to bind up while turning
