I recently got the car back on the road as they took away demos. I had the shop do an alignment and wheel balance. I noticed what seemed to be an exhaust type rattle hitting the frame. Twice I check the exhaust and it was tight. My brain finally kicked in and I decided to check the rear suspension and found a couple of bolts that I could tighten down a little more. They were no loose, but I could turn them a few turns. Could have been the tech or it could have been the poly caused the bolts to loosen just a tiny bit. Not sure but the banging is gone. Now I have to get the wheels balanced better. I think that problem is when I put the winter tires on they were all flat and so i just shot them full of the flat fix junk. I think that crap settles when it is cold and man does the car shake. I get rollin done the road for awhile and they tend to smooth out.

Any way I just wanted tell everyone to check the suspension bolts on your car. As I said they were not loose but I could turn them about a full turn.

Wait, did you mean you put Fix a flat in the tires to inflate them? You DO know that that will destroy the inside of the tire right? Its meant only as a temporary fix so that you can get a few miles out of the tire before you get to the service station and purchase a new one. Don't believe me? Say so and ill post pictures of what it did to the tire on my Jeep.
