Knocking noise?

within the past few months i've been noticing a loud knocking noise while going over bumps in everyday driving situations at any speed. the noise comes from the rear of my vehicle. If anyone has any insight it would be appreciated! thanks!

We need more information about what has been changed on your JK. Do you have an aftermarket rear bumper with a swingout tire carrier. If so it could be bouncing into the tailgate even if there is a stopper.

Make sure the spare tire is bolted on tight. I've made that mistake!

I KNOW THIS IS A BIT LATE BUT...it could be your rear seat belt harness blowing in the wind, I know that's what the noise was i investigated...this happens with windows and/or top down.

Some days you're the bug; some days you're the windshield.

I noticed a rear knocking noise right after i first got my JK. I don't know if you have a hard top or not, but the problem on mine is the long screws that hold the back of the "freedom top" on will vibrate out and then rock back and forth against the bar. Screw them back in and problem solved. Thats what worked on mine, anyway.
