I'd say alternator

 

[newjeepguy]

only does it while moving ,at idle nothing .i popped the hood and listened .nothing under hood .
checked the hubs too ,nothing jumped out at me .goes for inspection tomorrow .figures right .

If it only squeals while moving and NOT dependent on engine speed, then it's probably not the alternator.

I'd check the front brakes, may have a stone caught between the rotor and caliper, bent dust shield, or worn brake pads.

i had the front tires off to check the brakes today as it goes for inspection friday .didnt see anything out the norm . there was some lateral play when pulling the wheel from a 3 and 9 oclock position but thats something totally different going on .

it didnt start until this recent cold snap here in the northeast . it was intermittent at first then started doing it more and more .

been researching and the consensus says hub bearings but we will see .

for now i will revert to my ol standby "i will know what it is when it breaks"

I vote transfer case. Does it do it in 2WD or Fultime 4WD?

 

[newjeepguy]

does it in 2wd for sure ,i tried 4 full time and it done it there too . i will have to test again . i been researching it and alot have reported bad hub .

Does it do it all the time or only occasionally? I have a similar noise that only pops up now and then, and usually will go away after coming to a stop. It’s a really funny noise because it warbles a bit and is pitch consistent with speed. Sounds almost like holding a leaf or something up to a spinning bike tire.
Have noticed a similar sound, or maybe more similar to your sound or the one in that video, from at least one other passing WJ

drove it to my mechanics tonight(inspection tomorrow) started to hear the noise then it went away .

when i had the front drivers wheel off today the brake caliper was pretty darn tight against the pads .doubt thats it though

hey!! i finally found something that someone confirmed was the source of their high pitch squeal

double cardan joint in the front driveshaft or cv joint depending on which you have .

 

[newjeepguy]

turned out to be the drivers side front hub .

Figures. Just did the rears on a Compass and before they were replaced it sounded like a weedeater was running in the trunk. Cold and freezing seems to bring out the squeaks.

 

[newjeepguy]

yes the cold made it make the noise more .its gone now .until the other side goes .

the hub had no obvious play in it or anything .just noisy above 20mph .

What if it has the high pitched noise on a 2 wheel drive? My 04 Cherokee is doing the same thing. It's only 2 wheel

Well shit. Thanks for posting this. Have the same issue with mine
