    19557-010 is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Bigger and tougher where it counts. Impressed to see more material in the case and flange areas, much more than the stock GM unit it is replacing. This Eaton unit actually cost less than rebuilding the GM case that needed everything, spiders, side gears, plates & discs, cross pin and retaining bolt, plus the mounting flange for the ring gear had wear from a loose ring gear. So I choose the Eaton unit for its cost and the Eaton name, once I opened the package I was impressed with the overall quality. I did not read the details closely, the carrier bearings are also a different size from stock, I was able to source them locally the day I installed it. Great unit!
