i did a search before asking but no one said anything about the the drive train. will they say ur changing axle angles by lowering car and not cover some drive train parts??? i already bought suspension but im second guessing installing. my warranty though is another 2 years

It's very possible that since you're going to change the suspension geometry by lowering, that they're not going to want to warranty those parts. It could be the same for axles as well. Best bet is to talk to the dealership about it and find out - in the end, it boils down to what the individual dealer wants to cover. Some may cover it, others won't.
