My springs make no noise at all but I do have a slight rattle off and on which I think is the rear valance/bumper cover. It has those plastic screws that do not tighten up very well so I tried to snug it a little and it works for a while, then loosens again. I just haven't had time to get under there to see what I can do.
Those types of noises drive me crazy...any noise other than the roar of my 2.4. lol

 

Put a dab of silicone on the plastic screws & then tighten, & let sit overnight..

 

Good thinking sleeper, that'll do the trick whenever I get to it. I snugged them before vacation and never heard a sound until a couple days ago. Easy fixes when you have all these heads thinking at once. lol

 

Thanks IgottaWoody: I checked the spare area and tighten down the locking nut on the spare tire, the rattling sound has now gone away. I didn't think to check there because it didn't do it before with the old setup, I guess because the suspension is firmer it caused the locking nut on the spare to rattle occasionaly going over small bumps.
