I recently purchased the mopar heavy duty hinge upgrade kit and Teraflex Alpha HD spare tire kit. At first, I had lots of squeaking. I adjusted the mount/tire so it sits firmly against spacers and the rattling stopped, but now I have a new rattling sound when I hit significant bumps. I have a 37/13.50/20 Toyo/Fuel wheel mounted. I've torqued everything down twice and the rattling is still there. Any ideas?
