It is what it is. My friends and many of their friends who arguably use and abuse their Dually pickups far more than most owners, towing large heavy trailers all over the country following the racing tour, were having regular failures of the rear diff, specifically the pinion bearings.
They saw these Banks videos when they hit Youtube last year, and recognized a poor design, which ALL of the guys who had experienced pinion bearing failure, were using at the time.
They switched out their flat-backed diff covers on their rebuilt rear diffs, and low and behold a full season of racing, with no more diff failures...
I only heard about this because I was talking to one of my friends who runs in a sportsman class, and tows a large, heavy goose neck race trailer with his Dually pickup. Then he related the story of numerous other friends in the Sportsman classes with the same experience.
Bottom line: If you aren't using and abusing your pickup truck like these racers, you might not have a problem for awhile. But they and Banks with his videos pretty clearly demonstrated the limitations and consequences of the flat-backed diff cover design.
I should also add that none of them bought the new Banks diff cover, as it wasn't on the market when they rebuilt their diffs the last time.
