For the bearing nut lock washers:

Cage: 19207
Part Number: 7411378
NSN: 5310-00-741-1378

Inside diameter measures ~2.65" (obviously meant to go over the 2-5/8" (2.625") spindle for the M105A2 model).

The only place I found them is eBay. Just search for "19207-7411378". The first picture is from my trailer, notice the keyway tab is mysteriously broken/cut off. The second picture is from the eBay ad.

And this is the bearing nuts for the 105A2 model:
Cage: 19207
P/N: 7411379
NSN: 5310-00-741-1378

Info: 2-5/8 - 16, octagon, right-hand thread

Maybe this is helpful too:

I purchased the hub seals from Oshkosh (~$65 for 2, shipped. A bit steep IMO).

They were a good, tight fit, and appeared almost identical to what I pulled out.
What I pulled out:
Cage: 19207
P/N: 7411429
NSN: 5330-00-741-1429

One has to remove the seal anyway to get the bearing out to inspect/repack it.

Replacement lock washer arrived. Matching numbers and identical. Notice in the second picture that my original one is sitting directly on top of one of the replacements. Light surface rust like the seller promised. I should be able to clean it up easily and quick with a wire wheel.
