I've been amazed at the noise a lot of lifted JK's make on the trail. I was out by Elephant Hill last year and heard a JK coming that was sqeaking like I've never heard before; I don't know how he stood it. I had an annoying squeak in mine and found the culprit was the sway bar links. I've gone back, pulled everything apart and greased the dogs**t out of everything. Now it is totally silent in the roughest terrain. I'm really surprised that the lift manufacturers don't tell you to grease everything when installing their lift kits.
