I took mine in a few weeks back with a slight drift to the right. Dealer was not able to align to newly revised specs (5/25 TSB) and had to back order the bolt kit. The Service Manager said 600 kits were on back order nationally. I don't know what that translates into timewise, but I haven't gotten a call yet saying they got the kit in -- it's been three or four weeks. I'm wondering how they make the fix at the assembly plant. Do they put the bolt kit in there? If so, I'm sure they'll get their bolt kits before anybody else.
According to the TSB, the kits provide only a few tenths of a degree additional adjustment (I'm not sure to what alignment spec). I want to understand this problem better before I give them a go ahead to retrofit the bolt kit. I guess I'm not convinced it's going to resolve the problem.
