Looking to see if anyone has had their RDU rebuilt under warranty. What led to the rebuild, time frame for parts and completion?

Maybe you’ll be the first? What model/year & mileage are you at? Why do you think you may need a rebuild? Am I being too nosy?

I have a 2022 Lariat AWD with 4K towing package with 33K miles. The vehicle started to have a growling noise at slow speeds turning. After inspection by the selling dealership they stated the RDU needs to be rebuilt. There are a few TSB's out on the issue.
I've never heard of a dealership doing that in-house, generally they will just get a replacement assembly.
But at the same time, I bet some dealerships do rebuild transmissions and differentials.

Very interesting. I was hearing the same thing on my 2022 Maverick and the noise went away after draining and refilling the RDU. I'm at 61k right now so I think I no longer have coverage. That stinks!

I'm thinking that draining and refilling the RDU would work, not sure why they went straight to the rebuild option.
I had my RDU drained and refilled at 78k miles. I am now at 106k and it has happened again. I have an appointment with the dealership this month.
Dealer will just get a replacement assembly, it's been reported before at the Bronco Sport forum (Badlands, First Edition, Heritage Limited)

My 24 I swapped for redline rdu fluid. Seemed to work much better for traction. About 2 mo th ago I had the same weird sound after turning. Random awd disabled signals. Then nothing. Towed a lot of trailers in ff road adventures and about 20k miles. No such sounds again and everything seems fine.

My RDU failed at 21K my understanding is there are no parts available to repair these and no repair is to be attemped on the unit. This is a Dana part and is replaced as a unit. Mine was replaced under warranty no issues. I looked up the part Ford list was around $900 so not real expensive for what it is. The labor to replace looks like a PIA.
Had my rdu and ptu replaced under warranty around 45 thousand miles for a similar issue binding on under turns. Under warranty was in an escape for a bit over a month.
