Annoying squeak, need suggestions

[LumixLab]

I have a Gladiator Rubicon with a Jeep installed 2" Mopar lift. The lift went on at 5,000 miles the truck is now at 7,100. Recently developed a really annoying squeak in the rear end. It sounds like a rubber squeak, it's quick and in time with rough or gravel road vibrations. The rougher the road the more pronounced the sound. Can't distinguish a side. Shaking the truck back and forth by hand does not produce the sound.

I have checked the spare. Loosened it and dropped it a little for no change. I even over inflated the spare (35" KO2) and raised it up causing a really snug fit and still no change.

WD40 on every bushing I could find underneath and no change.

Do you think a suspension component with the new lift could be loosening?

Appreciate any suggestions on where I could look. Thanks.

Loosening of the rear sway bar bolts, and or rear shock mounts is a common one for anyone with aftermarket suspension on these trucks

I second Hunters post! Both mine and my buddies Rubicon had loose bolts on the front sway bars. His squeaked because the bolt was missing. I checked mine and they were just loose. Mainly right front. Checked everything and the backs were good.

I haven't experienced anything on my stock Gladiator Rubicon, but on my JK, every time we went off-roading, I would develop some kind of squeak below. I used to have my wife open the door and stand on the door edge sill and jump up and down to recreate it while i laid underneath, it took a few tries, but would always nail down what joint was causing it and add some WD-40 to it.
