Bringing up an old post I found and hoping to get some help.. I'm having an issue with the following set-up: 2015 Silverado, Black Widow edition - 6" Fabtech & 35x12.5x20 MT ATZ's. I bought the truck last week and noticed the wheels hopping/sliding when fully turning left or right. Thinking it was an alignment issue, I brought it back to the dealer to check. They made some minor adjustments but nothing was out of GM spec and the problem remained. I contacted Fabtech to see if there were any other specs i should use for the alignment other than what the manufacturer recommends after the lift but they said "not really". i did get the alignment specs for one of the trucks they (Fabtech) own with the same lift and the only thing i can see different than mine is the slightly increased caster angle. No idea what the issue is but very annoying and sure it will wear my tires prematurely. Based on my knowledge, it seems like whether turning left or right the outer wheel is over-steering and/or the inner is under-steering causing the outer to either slide or hop. Driving straight or in slight turns is great. Only see the issue at full turn. Also lost turning radius but kinda expected that with the lift/tires. I'm sending Fabtech pics of tread marks and tire wear and see what they recommend. Seems like the Ackermann angle is off but not sure where to start with ruling it out. The truck is back at the dealer today to align according to the Fabtech specs but not sure what to expect when I get it back. Always in 2WD and rarely use the auto 4WD feature. Disengaged the traction/stability control to see if anything changes but nothing. Other than that...Stumped Pic is of the skid marks left after turning left. Same is happening at a full right turn.
