Need help identifying stange sound

[Grip Grip]

I just recently bought an '05 Liberty 4WD for my daughter that's about to turn 15. Today I changed the oil and spark plugs, and next is this annoying squeaking sound.

Please take a look and let me know what you think. Appears to be something fishy with the rear tire too, but I'll check that out in the morning.

:Whoa: Birds have nested around the passenger rear tire & complain when you start moving! :shakehead: :gr_grin:

I'd just pull that wheel and have a look. Sounds like the tire is rubbing on something but could be brakes too.

Squirrel cage bearings gone bad.

Might also check U-joints. I've heard them sound like that. Otherwise, brakes or wheel bearings?

Good point. I've heard U-joints sound like that too.

I'd bet money it's brake pads. Prob the E-brake. Try driving the truck backwards slowly while slightly engaging the e-brake and see if it solves it. My e-brake was making all sorts of weird noises until I did this. Driving backwards causes a bit of a re-seat of the pads and in a sense, adjusts them. If it doesn't change anything, might need to dig deeper and look at the U-joints. Just had mine done, not too big of a deal.

Thanks for all the input. Unfortunately I was too busy cleaning the Liberty today to get around to investigating the sound, but I'll report back once I get to it. My plan is to put the back of the Jeep on jack stands and put it in drive so I can get under there an pinpoint the noise. My money is on the U-Joint. I did briefly check for wildlife, but none was present.

Sounds like a plan. Look forward to hear what's squeaking or chirping...
BTW in the forums we would prefer that you not call your Jeep or KJ a car, it's an insult! :icon_razz:

My guess is an e-brake pad separated from the shoe and is sitting inside the "hat" and rubbing. Mine made all kinds of weird noises when it happened - I thought the rear axle was on it's way out...

Update:

Here's a new video identifying the culprit. Sounds like it's the u-joint or rear differential to me. You can see that the squeaking is timed perfectly with the driveshaft. Now how do I fix it? Change out the U-joint?

By the way, the noise stops on deceleration or medium to heavy throttle.

U joints. Had that exact noise. The parking brake shoes would be more a ticking noise.

Did nobody else laugh at the OP's daughter's face in the end of that first video?? :rofl:

Good catch - got me laughing out loud! :happy175::happy175::happy175:

Sounds like u-joint to me. Mine is making the exact same noise. Got under there and sure enough they are visibly shot. Going to replace them this weekend.

Thanks for the help. I'm pulling the rear driveshaft today if I can figure it out. I removed the bolts from the differential, and have that portion separated, but the other end of the driveshaft is puzzling. I was under the impression that it was a spline and should pull right out, but it's not budging.

Cut the metal strap at the front on the boot and give a good quick jerk. Pull it with " feeling" It will come out

Thanks, worked just as you explained.

Just curious...what is that rubber roller/bracket assy that's attached to the top of the differential for?
