I'm in the same boat as u guys 2014 acl z92 gen1 lift almost 20000 . Had four pair of front tires put on, seven alignments ,still does the same thing . ALC had it for two weeks got it back three weeks latter started clunking found upper control arm bolts lose . Called fabtech talked to Armon he said the guys doing the alignments need to know how to read the tires and adjust accordingly, not just in the green . Don't know what else to do
