Ive heard that before but I got new bearings from rock auto, all timkens, for what I thought was a pretty good price. I think it was 100 or so. Can look at receipts when I get home.

Got lucky enough to find a good 79 donor truck with 3/4 axles and jumped on it. Had I realized the 3/4 axles weren't all the same for 67-72 to the 73-87 I would have looked harder and would have most likely had to buy one out of state and have it shipped to me. Around here a 72 donor truck goes for $2-3500, which is out of the question. HO 52.. isn't that a 3/4 axle? Im going from 1/2 ton to 3/4, or 6 lug to 8 lug. Obviously I didnt do my homework well enough and now im paying for it with time and labor, no biggie. I'll also have to go back and double check the front end now also.

Gotcha, thought you had the Eaton already.

There are some errors in that thread, particularly on the stud size and brake size on the 71 and 72 4x4 ho52 rears. 72 Had larger drums (12 x 2.5) And 71 had (11x2). Both had 9/16 studs.

I would appreciate some part numbers.

Thanks

Please let me know where you found this price on the bearings, RA is the cheapest I could find but like I posted above the kit is $481.

I could get a 2010 14 bolt with factory disks for $250 around here and a rebuild kit for $152 and still be into it less than a rebuild kit alone on the Eaton.

Thanks
