Hy 42bagged, the hub on the right in your first picture is for a 2 ton (bolt on dust cover), on the left is a 1 1/2 ton (threaded in dust cap). The outer bearing assembly should be 909025, the inner bearing assembly should be 909026. The bearing numbers translate as follows
909025 = B25, 909026 = B26
Timken B25 at RockAuto is $46.79, at Napa BRG B25 $109.00
I could not get B26 to cross at either site so you'll have to use your detective work for that one. As to the hub, try posting an ad in the parts wanted forum, hope that helps.
