You don't want to tighten the bearing to the point where the wheel won't turn. That will cause bearing failure. You have to preload the bearing. I don't have the specs here and it varies by appliication. Usually, you tighten the bearing using a torque wrench and rotating the rotor. Sometime that's all you do and other times you back off the nut slightly. Generally if you snug the bearing while rotating the rotor and back off the nut a tad, will put you in the ball park. When you get done, the rotor should rotate smoothly yet not have any in and out movement. Grab the rotor, top and bottom, and try to rock it. There should be almost no rocking movement. If you can't tighten the nut enough, either you were given the wrong parts or something is missing.

Look in a shop manual or Chiltons/Haynes. Most of the heavy trucks require you to torque it really tight, I think my 94 F250 requires 200 foot pounds. Then you loosen it up and then retorque to around 50 foot pounds. Be sure to check manual for torque, it may be way different for your model.

If it's a 2wd, you have to torque the Jesus nut but very little. You torque it to 21 ft/lbs while turning the rotor forward, then you stop, let the Jesus nut out 180* and then tighten to 18 ft/lbs again. That's a fairly light amount of torque. He's gonna have to take the rotors to work and use the old 30-ton press to get the old races out and press the new races in. (Remember which is the inner race/bearing set and which is the outer.)

Boy we sure would like to see these type on our 4wd 's huh ???????
Oh the fun of repairable bearings !
I hate sealed bearings!

you can get those races out with a brass punch.
put your new ones in the freezer for about ten min.,put the rotors in front of the heater.
Then carry the races to the rotor in a towel,and they will just about drop right in.
We used to do this alot.
