RoadWeary

I recently had something happen with the rear diff, and was looking to see if there were any TSB's or recalls out there, when I came across your post. Last week the brand new 2023 Transit Cargo, high top (with less than a thousand miles on it), I was taking on a long run on the highway had the rear-end lock up. The van was empty at the time. When I lifted my foot off the gas, the rear started "moaning" in a cyclic, rise/fall fashion, then the wheels started skidding and hopping. I managed to get to the shoulder. It wasn't the brakes, and nothing snapped off.. but there was the smell of scorched lube. I am wondering if something came loose in the housing, or something wasn't aligned and wore other parts til they failed. It was towed by flat bed, and I am now waiting to hear what the problem was.
