I’ve broken 2 rear shafts in Moab, wheel often with a 2000lb trailer and am still on my rear Detroit 18 years later... i Have had similar experiences with friends with Detroit’s, so from my seat watching nearly a dozen axle breaks with Detroit’s, I have the opposite experience— they have been wonderful. I’m NOT saying that they don’t break, they do, but I’d take exception to the statement that they almost always break when you lose an axle shaft. That hasn’t born out to be true. However, I would agree that when you do break a Detroit (on those rare experiences), it usually has an axle break associated with it. the Least reliable diff I have seen on trails has been the ARB— typically associated with actuation issues. I love my Detroit and I’m putting another in the Salisbury I’m building.
