    Michael, in your post regarding orientation of the oil seal, you advise ‘ place the hub on a flat surface with its inboard side face up’. I think you mean place the hub on a flat surface with the OUTBOARD side facing up, then install the oil seal with the channel facing outboard? I checked the Bentley manual (page 208) but unfortunately my illustration is not perfectly clear ...

    I've always tightened them to 100lb-ft. That's the recommendation for lug nuts on most modern cars, but for our old studs it's probably excessive (though I've never snapped one). I'd be comfortable with 80.

    Bob - don't most modern cars have 1/2" or 13mm studs?

    Good point. I believe you are correct.

    Let's refine/define our terminology:

    The O-ring (let's call it that as opposed to a "seal") and paper gasket are installed on the outboard face of the hub.
    The lip seal is installed into the inboard face of the hub by placing the hub on a flat surface--outboard face down, inboard face up--with the "channel" side of the lip seal facing outboard/down and the smooth side facing inboard/up.

    I hope this makes things more clear and sometimes a picture is worth 1000 words.
