I have a full floater job to do tonight! Bigger axle, though.

I do it like this on reassembly. Wipe the seal with a little gear oil so it slides on easy. Wipe a little gear oil on the axle bearing surfaces so the bearings slide on easy. Slide on your drum / hub assembly. Using an oil squirter ( think the of the thing used to oil up the tin man in Wizard Of Oz ), squirt oil in to the area between the inner and out bearing. Just enough so that it just starts to ooze over the outer bearing race. (If you look inside, you'll notice that oil will be above the middle of the rollers on the inner bearing, feeding the bearing and lubing the seal.) Spin some oil on your outer bearing. Install bearing and all lock nuts or washers spinning the assembly while setting the bearings. ( Setting the bearings means snugging the the inner nut, then backing it off to the set position.)

Put some sealant on the mating surface area of the axle flange. Usually, there is no need to seal the threads of the studs or bolts. And unless you actually have a gasket, no need to use one of those if you are using sealant. Install your axle. Just don't do like I do and remember that you forget to bend your locking tangs and have to pull the axle again!! It happens sometimes!

There will be enough oil in there to feed both bearings. No need to tilt anything. Remember, it is a spinning assembly, so that gear oil gets forced to the bearings when driving. When done correctly, you usually won't have to mess with the axle level, it will stay full. (Does it show that I do this for a living??)
