Outside tire wear. Can this be fixed by adjusting torsion bars

 

The PROPER way to adjust camber and caster both is by adjusting at the upper A-frame pivot bar.

However, if the truck has been "lifted" by a torsion key replacement or a key crank, it may be too much for the normal adjustment to correct. In that case, restoring the truck to factory ride height may bring the caster/camber into alignment range.

I'm not sure if it has been adjusted before. Do they sag over time needing to be "recranked"? My ucas are adjusted inward as far as they will go. I dont know how to pull the uppers in any farther to change camber. The front end does look lower than the rear by a couple inches just looking at it broadside

 

Good news!

THAT didn't change worth mentioning (the method at least!) from 1987 to past 1996; you can grab either the 1995 or the 1996 factory service manual from the FAQ list for a how-to on that.

But basically -

You loosen the two bolts that hold the upper control arm to the frame SLIGHTLY, just enough you can work it back and forth.

This will make a seasoned professional alignment tech cuss and swear, though; it's too easy to bump caster AND camber off while tightening the bolts (nuts for us 2WD folks).

If it was lowered by the torsion bars, or it's sagged enough with age, that could also throw it off.

Both years also include instructions on how to check the ride height and how to adjust it if necessary.

Here's a video on adjusting it; DO use a jack stand instead of just a jack, or do it on the ground with an impact wrench!
