I tried to search this, but didn't really get the answer to my question. I've changed oil in the rear differentials of many trucks/cars in the past. In the case of changing the axle seals in my truck (sig.), I button everything back up, then jack up the opposite side as far as the jack will go and add oil. Once I let it back down, I check the oil level and then just drive really slow for the first few miles. I usually drive in the ditch by the road, so as to slosh the oil into the side needing oil.
Since the fill hole bottom appears to be below the axle tube, does the axle shaft, itself, carry the oil out to the bearings in the hub? Can someone explain to me just how this works? Am I filling these diffs. the right way? Apparently it's working because I've been doing it for many years without trouble, but is there a better way? I've even done the same thing on the dump truck when I changed oil in it, but it's more difficult to lift that up and feel safe doing so when the axle is at that sort of angle on a jack.
