Looks like c bushings are next.
I'll say! Wow, negative caster, eh? Stock bushings still? Just go straight to 7's then.
Why did the tech adjust the toe to zero? Seems wrong to me. How did it drive after the visit?
And the camber is a bit off too. I would try to get the right side down some.
I think (but not sure) we like to see a little more camber on the passenger side, but unless you feel like lowering the left camber too, I would take the right down at least to .5 or so.
If it turns out that the right should have more (there are alignment guys here that will know for sure) then try to get the left to about .3 or .4, and the right to .5 or so.
If you want to go to the trouble. Which I would or your right tire is going to wear on the outside even faster than normal.
Even the rear seems a bit out on the right. Tweaked housing maybe?
Probably not a huge deal, but on a short wheelbase rig like these, every little bit counts.
If you're driving it around now, I would play with the toe-in settings. Maybe don't even bother measuring. Just twist the adjuster to shorten the tie-rod and drive it until you find the setting you like.
I would start with 1/8 to 1/4 turn of the sleeve at a time. Then tighten it down (always tighten the clamps before driving) and see if things improve.
If you're not really driving it regularly yet, you can dial down the camber and dial up the caster first if you want. Especially the caster. Anything in the negative range is bad.
And don't forget air pressures in all this. Our rigs rarely need the max pressures listed on the sidewall.
What pressures you running now?
