2016 JKu high pitch squeak HELPPPPP

Hey everyone so heres the scoop. I have a 2016 JKU, i have 18s with 35s, 2.5 rock krawler lift, teraflex steering stabalizers, it has been regeared for the 35s.

Soo now heres the problem. Its comes and goes this annoying HIGH pitch squeak squeal kind of noise only when i am coming to a rolling stop. So basically i hear it from 25mph and lower with my foot off the gas. I thought it was my brakes so i then changed my brakes to dynatrac conversion set up and that didnt do the trick. What could this be?!? Has anyone had this issue?!?

How many miles on the jeep? Did you only do the front brakes?

19,000 miles and all four corner brakes have been replaced. Bigger rotors, new pads.

Dirt, oil, grease on the rotors? Did you apply anti-squeak to the pads? Is it possible that your brake wear tab got bent towards the rotor a little?

You said it was happening before the new brakes, so probably not the issue...

Al professionally done by a reputible shop and this noise was happening with the stock brakes and the noise occurs when not brakes are applied it happens when i am rolling at like 25-30mph with no gas.

Sounds like something is going on with the pinion gear / bearings. Maybe the seal, but if it's not the brakes, you've got something going on with the other spinning parts. Can you tell if it's coming from the front or rear? You might want to try wiggling the drive shaft where they go in to the diff's and see if there is any play in them...

Ok so i got under it today and took a lok at sometings. Checked the U-joints and theres no play but i did notice this. The drive shaft going into the front looked like it was leaking this. Can this be the noise the high pitched noise?

Looks like your pinion seal is leaking. Before you do anything, you should pull the diff plug and make sure you have oil in it. I certainly wouldn't drive it until you check the diff level. If it's running dry, you will destroy your gears. It definitely could be the cause of a squeal.
