2008 R/T, AWD, CVT.
I feel odd vibrations, usually when accelerating in a turn. I'm thinking it's either the rear tires rubbing on the strut when fully extended, or it may be the rear gearbox (maybe low oil or something).
I do also have a bad squeak in cold weather - original bushings need replacing.
I have the front & rear swaybars removed. It makes for better climbing over things, and I can better identify which wheel may be having an issue.
Overall, I like the small lift. I've learned to climb sand dunes better, and the added lift makes it less likely to drag on things on the way up.
I still don't trust the scooter-style transmission, though.
