I am getting the same sound on my 2010 with 46,000 miles on it I had a driver side rear wheel bearing replaced about two months ago and the sound started about two weeks ago. I do have an appointment tomorrow to have the wheel bearing checked again. I have not checked my brakes yet being that I would think they would be good for a while still but will do so tonight. I will post my findings as well as check in to see what you come up with as well.

 

If it is brakes, they really are one of the easiest things to do yourself. One of the first mechanical things of any kind I did was change brake pads (drums on the other hand suck). I'm not much with a wrench, but owning a Jeep has made me better. If your not sure how, check YouTube.

 

Your fronts probably are good. Your rears are probably shot.

 

I checked the brakes and I am in need of changing them out the little indicator tab is rubbing so I am having it taken care of tomorrow. So that is what is wrong with mine probably what is going on with your rig too.

 

Brake pads look good. We've isolated the sound to the rear drivers side but still haven't found the culprit.

 

It may be time to get out a mechanic's stethoscope and start probing around. Do a visual for any small pebble that might be hung up in the caliper/pads. Also look for shiny spots that could indicate parts rubbing.

 

I had this last summer. Drove me nuts! I pulled the brake pads and dropped a little dry silicone spray in and around the retaining clips and it went away. Lasted almost a year so far. Also was advised to pull the clips away from the disk as far as theyd go

I dont always drive where others cant. but when I do, its in my Jeep. Stay muddy my friends

 

Bounced around on the bumper for a while this afternoon.. Shook the back end trying to find the source.. No luck. But whatever we did, the squeak is gone. That's all I really wanted!

 

I hope you figure out what it is. I did find out while doing the bakes today that the caliper was partially seized which is why my drivers rear wore out faster then the rest. I ended up having to replace it I was not able to get it to budge. replacing the caliper and pads solved my problem.

 

Of course... It comes back.
