H3 Weird squeaking

[awalsh]

I noticed this weird squeaking after I took the doors off. I think it started happening after I installed my rock sliders. I think it was because of the excessive amount of wd-40 I used to clean the threads. Anyone have any other opinions? I hosed down the suspension and brakes 3 times since it started and it's still there, but not as bad. https://vimeo.com/172223353

WD40 wouldn't make it squeak. Sounds like it increases with speeds. Look for something rubbing a hub, brake disk, axle, or driveshaft. It may have been there awhile; but you just started noticing it with the door removal.

I had the same problem when I first installed my Rocky Road Sliders. One corner was rubbing the pinch weld under the rear passenger door. You should be able to loosen the bolts and lower it a little. That solved it for me.

Put the doors back on - problem solved!

It definitely started after I installed the sliders, just wondering if wd-40 could be the culprit. I'll first try to lower the sliders and if not then I'll start to look into something rubbing. Oh and the doors are back on [emoji23]

Update: I figured it out 99% sure
I didn't reconnect the drivers rear brake line next to where it bolts on when you install the rocky road sliders

I'm still in a loss of words, I cannot figure out what is making all of this noise. It's definitely coming from the rear:
It's not the parking brake
Could be breaks rubbing the pads
Not brake fluid
Not rear dif
Possible wheel bearings? I don't know much about those
Should I go get everything shot with a grease gun and have them check to see if my brakes are rubbing ?
Tomorrow I'm going to take off the sliders for the h3ll of it to see if that's the problem
If so I'll probably cut some rubber sheets and put them behind the mounts

Sounds like a u joint on rear driveshaft

That's what I'm thinking.. But what are the options on fixing it cheap so I don't have to drop tons of money if it still isn't the problem, just a new u joint? Or do I need a whole new driveshaft

New u-joint. $22 and a half-hour.

There was no internet or u tube the first time I changed a u joint had to buy 2 of them I had needle bearings everywhere lol.

 

[awalsh]

Can someone link me to the part?

Also got it looked at and the guys said its my ball joints but they don't spin so how could it squeak? I'm still going to replace the ujoint

They don't spin but they do move. You can spray white lithium grease into the boot of the suspect joint and if the noise goes away you need a new one.

Ball joints aren't going to make that noise, increasing as your speeds increase. It has to be something that rotates. I'd find a new shop.

I'd jack up each corner and spin the tire, listening for the squeak. If none, that likely rules out bearing or brake issue. How are your brake pads? If worn, it could be the wear indicator on a brake pad contacting the disk; exactly what it's supposed to do.
