Alignment Fine, excessive tire wear..

Hey guys so I haven't been on here in a while. Glad to see this place is still kicking. So a little info on my truck, it has a 3 inch Toytec lift with OME 885's spring and that little spacer over the top of the coil spring. About about a month ago I noticed that I had pretty good wear going on with my left front tire. I haven't done an alignment in about 3 years so I figured it was about time to get it done. There was no pull and the only reason for the alignment was the wear. So I had it aligned at the same shop and I told them to rotate the tires so I could check if that fixed the problem. After about 200 miles or so, the tire that I rotated on the front left is worn down significantly as well. My alignment specs seem good. Caster is low because I am on stock UCA's, but I don't think that would affect tire wear.
Caster Left= 0.6 Caster Right= 0.7
Camber Left and Right=0.0
Toe Left= 0.00 Toe Right=0.05

Right tire is fine. No wear at all.
What do you guys think? I know some people are probably gonna say to get some new UCA's but I ran perfectly fine without them for 3 years before this.
