Thanks to Chris McKeon for
lending me his Honda Power Washer a second time to wash the axles (first
time was to wash the T-18A transmission and Dana 20).
washers are great to cut the grease of years of use. Just be aware
that they blast water or solvent into all the seals as well. That
being known, I always wash the items before rebuilding or refilling
with gear oil. The items that needed washing here are the axles and
some of the outer Dana 30 items like the rotors and outer knuckles.
With the rotors, I didn't remove the bearing so I covered them with a
plastic cup while pressure washing them (seen in the background).
I found that a good washing, followed by
primer and paint works well before tearing down the item in
question because a few reasons. First, rebuilding an item or
fixing something is hard to do if it's all grimy and greasy.
Second it's easier to wipe oil away after it's been rebuilt if
it's been painted already. Also the fact that you don't want
to damage new seals by power washing something for painting after
it's been rebuilt or worked on.

The axles were power washed and let to sit in the
sun for a while to dry. Soon after I hit them with a coat of
