Just wanted to double check with you guys since you seem to know just about everything about these trucks. My 93 4x4 regular cab 3/4 ton is wearing the outside of the passenger side tire badly and pulld hard to the right driving at any speed.
I'm guessing I'm toed in too far. Anything else I should check?
I changed the drag link and right tie rod end back when I got the truck and thought I measured the toe in correctly. 1/4 inch toe in. Should I even bother or just take it to a shop for the alignment? Thanks guys, I need this done before I go for my new tires. I thinking 285/75R16 Yokohama Gealander AT's.

 

If your tire is only worn on the outside it is a result of excessive positive camber, if your tire is "Feathered" across the tire, that is a result of excessive toe.
Have you had a good look at the ball joints? If everything is tight an alignment will straighten you out.

 

ya, in my experience a toe problem looks like the tire is being 'scrubbed' in the wear area. Hard to explain exactly what it looks like, but it's not just a clean depletion of the tread.
