Is your ST AWD?

They seemed OK, I will check again. No noise when switching to neutral, no change in pitch when turning, so I had ruled them out.

Hi guys, I have a harmonic noise in my rear diff area that the dealer can't find. We have replaced the diff twice, and the driveshaft once. Gonna kind of ramble here, don't know what's relevant, but y'all are pretty smart on here. It sounds very similar to this: Hellcat rear end whine. It...

I’m sure some noise is normal and not cause for concern. For what it’s worth, my ‘22 was dead quiet with the same setup. The noise I’m encountering on the ‘23 cuts through radio and exhaust and lives in your head rent-free. 60 mph is a very unfortunate spot to encounter the issue consistently.

Small update for future readers. Replaced the OEM carrier bearing with a JXB and it made no difference. Driveline feels tighter though, cool mod (y)

Upgraded with the JXB carrier bearing today. Noise didn't get any better or worse. I can definitely feel the driveshaft now, though. I'd imagine that's expected and doesn't bother me much.

Just had my timing cover replaced on my ‘23 too. Dealer happened to catch it while doing plugs. Doesn’t seem to be very common.

Interesting tidbit... the howling is completely absent when it's cold out. It's generally louder the nicer the weather is.

Dealer told me they do tear down the diff, just replace the entire unit and send it back to Ford. Wasn't able to get a good answer.

Follow up to this... I had the rear end replaced again. Both replacements started howling from the second they were installed. No solution yet.

Anyone figure out the howling from the rear diff? I'm on rear end #3 at 18000 miles, they keep finding metal in it and replacing it. 2nd driveshaft too... first one was eaten up. Brand new diffs are howling the second I drive it off the lot. Throwing a driveshaft carrier at it soon.

I'm on my 3rd rear diff and 2nd driveshaft and the dealer can't find this noise. Mine's at 45 mph and 58-62 mph, accel and decel, but louder at decel. Throwing a carrier bearing at it, don't know what else to try. AWR brace on mine is almost like a stethoscope to an underlying issue. I did some...

Dealer diagnosed this as a bad pinion bearing for me today. Started at 3k miles, got very loud by 5k. No leaks. Just bad setup, I think.

It got me too… what a mess

Found it. Swear that wasn't there the first time I looked ... :)
