Torque specs
I haven't grabbed a repair manual for my 81 Ford 4x4 yet. Would anyone happen to have the torque specs handy for the front wheel bearings? I plan on repacking them this weekend, and want things to be right upon re-assembly. Thanks in advance.
Edit, my old 69 Ford was 80 ft/lbs, and back off 1/4 turn after torque. I need the initial seating torque spec, and the amount to back off, so I don't end up burning up a perfectly good set of bearings.

It depends on what axle you have.
For Dana 44-IFS
My book says for the inner bearing nut tighten to 50 ft lbs then back off 45 degrees.
Then to lock it after aligning it with nearest lockpin alignment, put on outer nut and tighten to 150 ft lbs. End play should be under .006 inch
For Dana 50
Inner nut to 50 ft lbs and back off and then retighten to 30-40 ft lbs. Then while turning hub, back off inner nut 135-150 degrees. Then put on outer lock washer and nut and tighten it to 65 ft lbs. End play should be between .001 and .009 inch
Later Model Dana 44 with manual locking hubs
While putting inward pressure to unlock adjusting nut, tighten to 70 ft lbs. Again push in to unlock locking tabs and back off 90 degrees. Retighten to 15-20 ft lbs. This one should have NO end play.
This all from page 8-23 of my Haynes, hopefully it is correct.
