Odd squeak, only when cold

[ATL_Rubi]

Okay got a fun one.
23 Rubi, 8at, 1.5 inch teraflex level, no other changes.
Have an odd non consistent squeak, only when the jeep is cold. After a few stop lights/accelerstions, the squeak goes away. Sounds likes it’s coming from the passenger front wheel, but as it’s not consistent, I.e. every rotation, or every time I turn, I can’t pin down the cause.

I suspect a brake pad hitting the rotor, but no scoring of the rotor.


Hard to tell but the video is a slight incline, I don’t brake until 5 feet before the gate.
Pls. Send help. It’s driving me up a wall

I have sound exactly like that since new - only when cold. Now at over 65K miles. I think it is from the driver's rear tire. I think it is the emergency brake sticking. Try playing with the emergency brake, going up and down. That makes it go away for me. If not, it could be the disk brakes sticking. Hit the brake pedal a couple of times fast and see if it goes away. I will address it when I change the rear brake pads, which still have a long way to go... lol..

PS. On your disc brakes, make sure you are not missing the spring clip that opens the brake pads when you let off the brakes.... Note: I actually had one missing on my rear brake pads and replaced it, but, it did not fix that squeaking noise.

That’s my thought too, the brake pads. Explains why it goes away after a little bit of driving. Of course I could bring it to the dealer, but with my luck it’ll go away when they drive it.
Also will figure it out at brake change but as you mentioned, far far off. Only 23k miles

lol, I brought mine to the dealer 40K miles ago and they said they could not re-create it. Of course, I heard it again the next morning... I do lots of 4wheeling. lots of dust. I tend to think it is dust in the emergency brake drum, so, when you shake the emergency brake lever, it goes away.

Note: The emergency brakes are inside a "drum" on the rear axle. The disc brakes rotor are mounted on top of that drum. So, it could be either of those making the noise.

Welcome to the club. There are other threads on here about the same issue. Some members have suggested broken brake pad clips as the possible culprit but that hasn't been the case for me. I've had the issue since about 35k and I'm at 53k now. Dealer says the brake pads look fine and have plenty of life left. But I do think it's brake related and probably won't resolve itself until the pads and rotors are changed.

It’s a blessing and a curse to hear it’s a brake pad issue, as these pads last eons. My JK had the stock pads until 110,000 miles. I’ll bring it in eventually and see what they say, but I suspect you’re right, brake related.

I have a 2020 ,rotational squeak is what I was hearing when cold . Then our club was in a xmas. parade and I heard the squeak for 20 blocks . Now they changed the rotors, drums, calipers .
The squeak came back. Now in the shop again ,they are changing out the driveshaft ,rear axle. I hope that takes care of the issue.

I’ll need to do a window dance and roll some up and down to better localize the noise, but for me it seems it’s coming from the front.

Hopefully that solves it for You! If you don’t mind, could you report back if it does?

Flash Rust?

Thought the same, but it’s consistently coming from the same general area. Happens if I park inside, outside, wet, dry, cold, hot. No difference so far that I can tell. Have an appt set for the 11th.

My rear and front driveshafts have been changed. It did not change the squeak. So, the axle change is your only hope -- I think.

Here ya go folks .They replaced driveshaft and rear axle .
Guess what ,squeak is still there. I had my shop foreman stand next to my vehicle when I pulled out FRIDAY.
He says I need non copper brake pads . So today he put on a complete set of ceramic brake pads.
I will know at 4pm. if that solves the issue.
