Intermittent hum or howl from front end

[keb]

I have a work order documented from the dealer that it is documented noise and waiting for a Fix and I would like to know more about that TSB if anybody has any information because I believe there’s a good handful of trucks in the northern region that does this

I did stop at the dealer had them print out that TSP 25 2513 and then the old one that I had done it appears to be but I’m not 100% sure that basically they included 2025 and there’s a new service procedure for diagnosing this

Mine is doing it too... doesn't seem to be temperature related. Can only hear it when coasting in 2wd, mostly after long drives (3-4 hours). If I touch the brakes or let the truck decel, it goes away. If I give it some gas, goes away. And when I engage 4a or 4h, goes away. It's like a weird resonance when there's no load at all applied to the front driveline...

That doesnt seem the same but who knows.

Mine last year was very consistent. Same distance away from start, only resolved by cycling 4x4.

I can't find anything on that TSB. Alldata doesn't have it listed yet.

I stopped at the local Ford dealer and got a copy of it

Checking for the issue seems rather DIY if you can manage to get the truck up off the ground. I wonder if you could even do it just getting the front end off the ground?

I bought a 2021 limited 6 months ago with 46,000 miles. This is my first ford and already have 56,000 miles on it now and just started hearing the hum. Most frequently at low rpm’s and sweeping left turns. Has anyone been able pin point the issue/fix for this? I’m quickly approaching 60k miles and hope of anything being covered under warranty.

I’ve already taken my truck into my local Ford dealer for an oil change/service and didn’t have the best experience. Hoping I can help lead the horse to water and avoid being dicked around by the dealer.
