Drivetrain Chirping/squeaking Noise

[PNBLWZD]

Hi all. I started noticing a chirping noise from under the Bronco at low speed (<20 mph) over the last couple weeks. 2024 heritage ltd with 850 miles.

Frequency changes with ground speed, but not engine rpm. Develops after about an 8 mile warm up drive to and from work. 2H or 4A makes no difference. Rolling in neutral makes no difference

Frequency of the noise is rapid, faster than tire rotating speed, so I think it’s driveshaft related, dry u joint, differential or…?. Stops when truck comes to a stop.

Video sound clips attached, but faint. Please have a listen and see what you think. Thanks!

Check the 'GOAT mode' selector, you may have chosen this (specific to the Heritage model) instead:

That’s pretty much what it sounds like!

Taking to dealer tomorrow

Update: Dealer service dept replicated the noise on the street and then listened while up on the rack to locate. Coming from inside the transmission apparently, waiting for the Ford tech line to authorize replacing transmission.

I haven’t read anything about transmission issues on here. Am I just lucky or…?

You’re just lucky. Never heard any kind of a noise like that from a 10 speed

Any new update on this? Did the dealer replace the transmission?
I just started to get that same exact noise on my 23 black diamond. 13,850 miles
Only happens after it has been driven a few miles.
