for the dana 70 wheel bearing nut ?
on my '93 dana 60 it's 50ft/lbs, but on my '63 w300, everything locked up way before i got to 50.
thanks

Assuming it is the closed nuckle axle,
It looks like have a bearing adjustment independent
of the drive flange since it used tappered bearings
the drive flange is bolted outside, for the nuts on the drive flange bolts to drum book gives 30 to 35 Ft Lbs, so 50 would be a little high.

Never done one myself, just out of my 62 book......

all the wheel bearings i have ever installed wernt torqued. i run the nut in till it was snug to seat the bearings, then backed off to the next cotter pin hole, or about 1/8 turn if you got the lock tab washer.

thanks both
the 50ft/lb number is from a dana manuel i dl, but couldnt find anything for the 70.
the drum stopped turning way before the bearing was even seated, but didn't have time to check it out. i had the shoes off,etc, so maybe i'll back off the shoes to see if it helps the bearing setup

you do need to have the shoes backed off and not rubbing or youll get an inaccurate "feel" when tightening things.

That's going to run them a little loose. Taper wheel bearings should have 35-40 in-lbs of preload. The bearings should first be run down tight to force the grease out, so that a false reading doesn't result. Then loosen them up and retighten them snug. An inch-pound torque wrench can be used on a wheel nut to test preload, or if you don't have one, give the tire a good hard spin. Preload is correct when the tire makes one complete revolution (from the point where you release it) and stops. If it spins more, tighten them a bit; if it spins less, loosen them.
