Hello some potentially dumb questions here, bear with me.

Context:

Installed the Z1 spacer lift + FUCA + eccentric bolts both arrows facing inward. Then aligned at my local Les Schwab but it took them 3 tries. The first time they didn’t even realize the upper control arm was adjustable despite me providing them the manuals for them. Now I realized I have rubbing at full wheel turn when backing up despite a 2.5” lift and stock tires. The issue is I’m past the 30 day warranty and tired of dealing with them.

Questions:

1. I think this is due to the wheel being to far rearward in the wheel well, I believe that’s called caster. Does this seem correct?

2. Can I adjust caster myself without redoing my alignment the rest should be in spec?
