Steering Wheel Installation

[srvivor71]

Does any one know what the proper torque for the steering wheel nut is supposed to be? I had my wheel off and since I put it back on, it has been binding up when I drive - instead of returning itself to center, it gets hung up and I have to force it to return to center. I'm thinking I may have overtorqued it and got to wondering what the spec is for this. I haven't been able to find it with a google search.

Also, is the steering column shaft supposed to be able to travel up and down along its length by about 1". That's what mine did. Is that normal?

Any advice appreciated...
