Yes, that is exactly the problem. The H3 housing flexes without wheel spin. Its just too light for the application. Any mods we could do to it to reinforce the housing ( like heavier, stiffer cover or billet steel bearing caps) would only be patches to something that was built too flimsy to begin with. Its like building a big house on a poor foundation- things don't stay square very long.

I have had this happen on big truck rearends that were speced too light for the service they were in. The fasteners that held the bearing caps would elongate under load and the results were the same as what we see here. Within 2yrs time all of those units on that order had experienced ring gear breakage.
