I beg to differ Big_John. The Dana's in my Dodge trucks and the eaton's in my semis are bathed in the same oil from the diff. The procedure for refilling the hubs after service is to jack up one side so gear oil drains down the tube from the differential to refill the hub, level it and top of the diff. If you pull an axle you better have a catch pan handy.Wheel bearings in a full floating rear don't come anywhere near the oil in the rear end housing.

An 8 3/4" rear, for example, is a semi floating axle. The oil seal is inboard of the wheel bearing, so that bearing doesn't run in the oil either. In fact, the wheel bearings on a 7 1/4" Mopar axle are sealed ball bearings. I just replaced a set on my Barracuda.
Difference between full and semi floating.

OK, I just learned something... I guess my problem is I focus so much on the cars from the 60's and 70's that I don't know what is going on with modern stuff.
