Help with 3/4 ton rear hub/drum instalation?

I had to completely rebuild my '69 C20's rear brakes. I am installing the hub/drum assembly and the manual says to torque the inner wheel bearing nut to 50-60 ft. Lbs and the outer to 170. The problem is that when I torque down the inner nut the hub/drum assembly no longer spins freely on the spindle. Is this correct? Should I loosen the inner nut to allow for free spinning movement or do I just follow the manual?

I am hoping to get wheels back on today, so any help is appreciated greatly!

Paul

I think your missing a step. After the inner is torqed, it should be backed off 1/8 of a turn or something like that. If you can't find the proper specs, I just back it off, the hand tight on the inner nut.

Okay, I get the backed off part, but is the assembly supposed to spin freely once done? Mine are both very hard to spin by hand and the shoes are not touching the drum.

Thanks,

Paul

My big ol hubs on my Eaton rearend spin with ease.

I tightened them down pretty good then back em off slowly until they spun fair and locked the lil washer over.

Thanks everyone! I am going to pull the axle shafts and redo them so that they spin freely. I'm glad I checked with you all here as I would probably have ruined those expensive new bearings.
