Hey their boys and girls i'm new to here and just thought I'd throw out a question on this. I just got this 2009 unlimited x with a 4in lift and tires already on it to replace my 2010 Rubicon that got stolen. It sounds a little loud like something is vibrating or something. With a 4 in lift on the jk's aren't you supposed to either drop the tranny like and inch or put raised mounts on the engine to correct the drive line angle? it drives just fine but I'm just looking to get rid of that noise and eliminate any future problems. if anyone has any input on this I'd greatly appreciate it.
