I have a squeak In the rear of my jku that started out when I hit bumps now it is constant. The sound is similar to the squeak/rattle a case of water bottles makes while being hauled or maybe a styrofoam cup up against something. I've gotten under the jeep and pushed/ pulled trying to find it. I thought it maybe shocks, or coil spacers, but it sound like it's about all that in the fender well. I've sprayed wd40 hoping that would help. If anyone has any idea what it may be or how to go about stoping it please let me know.

 

Check your gas filler line push and wiggle it. Mine was squeaking like a SOB. for a while and bugging the hell out of me

 

Hard top bolts need tightening? If u have a hard top that is....

 

Nah this happened to mine. I'm tired so I can't think of name of bar. Look under back and you will see where a bar goes across jeep and through like a rubber sleeves. Squirt some 3 and 1 oil on it and it'll stop

 

The sway bar?

 

Try using white lithium grease on all the bushings

 

I was having a similar sounding squeak when I had my Freedom panels off. It either went away or I just can't hear it with the panels on and it's been too cold to take them back off to try and find the problem. I'll be interested to hear what you come up with.

 

make sure everything is torqued correctly (control arms, track bars, etc.). I had this and it was due to one of the bolts on the driver rear getting loose. If after you torque everything and it's still there, it could be one of the other items mentioned above or you could have bad bushings or a wallowed out hole.

 

So I finally found and fixed my squeak. I kinda feel dumb it's something I should have noticed when I installed my lift. But after crawling under the jeep for the tenth time to look I noticed the bolts used to install the coil spacers were rubbing body. I removed them cut them down 1/4" and bolted all back up and problem solved. Thanks for the help guys everything y'all mentioned I tried.
