Just a tip. For the rear diff, I've found if I let it sit for a minute or two after the first overflow, it will take another squirt or two of fluid before overflowing again. While this is not critical, I thought you might like to know.
Also, I've found that if I don't use a quart pump on the hypoid gear oil, I can only use about half the quart bottle trying to squish it against the frame when filling through the fill hole. The pump is easier in this regard, but is also something else I have to clean up at the end. So if I just have a couple partial bottles of hypoid gear oil, I top off one before filling the transfer assembly. Or just use my qt hand pump and quit being so lazy about clean up duties.
