Spindle nut torque spec
I only tighten the nut hand tight. It's a lot easier on the bearings in the long run. I ran my D150 pickup over 200,000 miles on the original bearings. I have over 154,000 on my current truck and it still has the originals in it also. Just make sure the bearings are seated. You can do that with a wrench or channel locks. Then back off the nut until it's loose and retighten by hand. Install a new cotter pin and you're done.
