Wheel bearing part number is
L44643 which is a standard trailer bearing part.
Didn't pull the races out so I'm not exactly sure what the part number is on that. I would guess the part number would be
L44610.
Seal part number is
12411 which looks like the equivalent part numbers are National 203029, National 204029, SKF 12506, and Timken 204029.
After cleaning up all the grease and bits from the parts, the bearings look fine with no scoring or pitting. The races seem to have some wear but no scoring or pitting on the surfaces. The seals were hosed and cracked. The shim (worn on the bearing contact edge) seemed to be the part that was flaking the metal bits into the grease but luckily didn't damage the bearings/races. I think the looseness of the setup was causing the shim to bang into the spacer washer and chip away.
After doing a quick reassemble of everything except fer the seals, everything was close fitting without any wobbling or wiggling. Looks like I might be able to git away with just replacing the seals, grease, and 3 cotter pins fer this hub rebuild.
