Hy Chinito Quan, I have gone over your bearing list,
187434 - I could find no reference to this number in my parts books or my bearing cross reference
954462 - crosses to a Bower 5306W
3705725 - changed up to 3776800 - which crosses to National 6818
592441 - crosses to National 5801
111121 and 370251 are probably replaced by Bower R1502EL
I believe the pinion bearings you need for this differential are
1 - 7450371 which crosses to Bower HM89449-HM89410
1 - 7450373 which crosses to Bower HM88547-HM88510
Front wheels
you have listed three different bearings here, obviously each front wheel only uses two bearings, I believe we're dealing with a 1/2 ton chassis here built between 1946 and 1957
inner bearing 909052 crosses to Bower B52, that is the number for the complete bearing
outer bearing 909001 crosses to Bower B01
3656536 seal crosses to National 6064
I hope that helps, I would like you to post the trucks serial number so that we may decipher it and know at least what chassis we're dealing with, I'm pretty sure that the rear axle has been changed to a 55B - 59 1/2 ton
