Okay pros, help me please. I have a 2010 jk 4door mtn edition with less than 5k on it. some time ago, i bought a 2" lift kit (6 pieces of rubber, no shocks) and had a local garage install it for me, when they put on the new wheels (same tires). I now have a "clicking" sound coming from underneath, mainly the front end of the jeep, when I hit bumps,.. going straight or turning does not make a difference. It is not a heavy sound, and does not seem to affect the drivability, it just makes my pretty little jeep sound like a piece of crap, and it seems to be getting worse as time goes by. I have also noticed, on the highway, that I get considerably more shimmy, starting at around 65, and quite a bit of random "chucking" like there is not enough play in my shocks now. I've been underneath, jiggling things around and I can't find anything loose, but I am far from being a mechanic, and there really is no one else in this small town qualified to check it for me. I would take it back to the garage that did it, but I'm afraid if they work on it again, the next time, a wheel may fall off or something. Any suggestions would be greatly appreciated. I don't do a lot of heavy work on my jeep, but I'm not totally inept, or opposed to learning something new. thanks in advance, all.
