Climbed under the coach (don't like doing that) and found the tag on the axle, I have a Meritor 23k lb unit with manual diff. lock and Bendix air disc brakes.  Called Meritor to get the correct bearing and seal numbers, they are very helpful.
Outer bearing and race numbers are 580 and 572
Inner bearing and race numbers are 594A and 592A
Meritor seal number is A1205V2492
Bearings and seal are in their way, should have it back together late next week.

Hey Jack, did you order the parts from Meritor?
