I'm getting a loud creaking noise from my rear suspension when I go over speed bumps or hit dips. I sound like I'm driving an old covered wagon! I think it's coming from the rear sways that I just installed a couple of months ago. Can anyone recommend a lube, and maybe also suggest where to lube it? WD40 did absolutlely nothing. I don't want to use anything that might deteriorate the poly bushings.

 

I have the same noise, it only happens over speed bumps or when I'm backing out the garage.

I haven't fixed it yet but every morning I get a reminder, hopefully its an easy DIY.

 

I've heard of wrapping the sway bars with teflon tape where they come in contact with the bushings.

I don't see why you couldn't put a blob of moly-lube on it though...
