OK then, my best guess would be the same principle, however you can't hand tighten it. I'm gonna have to go with calling your shop or look in a service manual to get the proper torque specs. I could guess, but that would not be very good considering it's your front wheel that's being tightened down. If I were doing it, I would be comfortable with what I did, but I can't tell you to do the same.
OK, so I looked on a couple other forums, and the consensus is 180 ft. pounds for the axle nut. Whether or not that is correct, I don't know.
