So I have a 2010 rubicon 2dr. 18xxx miles on it. I just installed a 2.5" rough country spacer lift. And wheel spacers from rough country. I made sure all bolts were tight and retightened bolts a few days later. When I drive alone it does not squeak. When I have a passenger riding it squeaks at the rear passenger side. It is really loud inside the cab, but not too much outside. It has stock 32" bfgs. What happened and how to fix? Thanks

 

The first thing I would check is if your rear sway bar is rubbing on anything

 

Also make sure your coils are seated properly

 

Does the rear coils sit a certain way?

 

Bump for help please

 

Yes, the coil should be rotated so the end of it hits the small tab in the coil bucket.

 

There is no tab on the rear coil mount, there is one on the front ones though

 

Ya. There is no tab at the rear. It looked to me as if it just sits in there.

 

The problem is obvious. You made the mistake of purchasing and installing Rough Country parts. :( I made the same mistake with my first lift. I now run Skyjacker springs and shocks with JKS trackbars and discos. Do yourself a favor and avoid RC in the future. Sorry.

 

Might be a seat squeak if you hear it more in the cab.
