Anybody seen this before?

Check king pins, check the nut on the axle. When the bearing wears the axle nut gets loose and creates play. I would start there

 

Thanks man. I will admit that living in it helped though. If it weren't for that, then I probably would not have been able to pull it off.

 

Ok, sorry missed that. If you haven't check tie rod ends, and pitman arm. Check rear bushings on drives. Lastly could be a bad tire.

 

Here is what was posted on another thread about golf balls.

just get a bag of recycled golf balls at walmart keep in truck .put 3 golf balls in every tire on truck.i guarantee the tires will wear smooth as a babys bottom unless they are structurally compromised. this will save you lots money, keep tires inflated. if some tireman laughs, thats ok, he wants y.our tires wear out he makes money selling tires. been using golfers over 15 years..you couldnt give me a set of centramatics. period. beads and sand outa question 2

 

I have the centramatics and have to believe they do work

But I used to have a few trucks and an old driver that worked for us swore up and down on the golf ball thing

Haven’t tried it yet myself but I believe it’s a better option than the bags of beads etc

 

I've just Never got good wear out of anything but michelins on the steer position of any truck I've ever owned and won't throw my money away on anything less these days .
Firestones were always rough riding choppy junk that lasted maybe 90k .
I run the drives down to about 10/32s throw on 8 new yokes or hankooks .

 

I agreed with you until I started running 295/60 on the steer. With Michelins, the shoulder goes away too fast. Don't like the Continentals because they look like an aircraft tire (just smooth with 3 deep grooves) halfway thru their life, but at least I can get over 100k out of them. The Michelins seem to be getting better, albeit slowly, but they just don't hold up to our side loads in carhaul. Only good thing about how fast we go through tires is that we never see the river wear the OP is dealing with.
