1/2 ton 2wd front wheel bearings repair/replacement...

Its been awhile since I last had to do wheel bearings on the front of my truck. I don't remember the torque spec to preload the bearings, does anyone have that? My front driver side is bad. I recently replaced it, but I didn't torque to spec to preload the bearing, I just PFT'd it, then backed it off to the next slot on the castle nut and called it a day. Its bad again and now I have to repair it. I hand packed the bearings, installed new races with my press and installed new inner seals. I don't see any reason for this to have failed except I didn't torque it to preload the bearings. The bearings are Timken so its a quality part... maybe something has changed, but I think its my fault.

Torque spec please and any advice on something I may have overlooked during the procedure would be wonderful.

Thanks!

Torque to 80ftlbs spin the hub to ensure the races are seated and square. Back off then finger tight

x2, factory GM service manual. Torque to 12 lb-ft while rotating the rotor, then back off to just loose, hand tighten as much as you can with your fingers, and back off again to the nearest slot in the castle nut to cotter pin it. Straight out of the manual.
