Sean:


See "Engineer to Win" by Carrol Smith, page 142. ".. the ideal length of engaged thread in a tension bolt (or stud) application is 1.5 times the bolt diameter."


If I were you, I'd do some serious checking of proper stud length for your wheels.

All the damage shown on the stud seems to be on the last 1/4 inch or so.  This seems to indicate inadequate depth of insertion of the stud into the lug nut.  When the torque was applied this resulted in the threads on the stud and nut deforming due to the limited interface being inadequate to support the load.  When you tried to take them off, the deformed threads wouldn't turn and the stud and lug nut "became one".

     I don't have any specs handy, but I seem to recall that the stud/nut
     interface is supposed to be something like twice the diameter of the
     stud or something like that.

     In an over-torque condition, a proper stud/nut interface should
     result in the stud breaking off before the threads fail.

     Anti-seize is always a good idea.

     Since you are going to tear the thing apart, you might investigate
     this a bit more and make sure you have the correct stud length for
     those wheels.

     And as usual, "your experience may vary!".

     You are using the jack between the bottom of the wheels and pushing
     them against each other??

     I'm with Jeff on this one. Pressure baby pressure.
     I have had to do this a time or two. I have two 4" X 4" with about a
     6" X 6" plywood screwed to the ends. The plywood goes on
     the inside of each rim, for protection. You then place a scissor
     jack in the center to apply pressure against the rim. Not too
     much pressure, just enough pressure.
     Make sure the spinning stud is down on the bottom to get most of the
     pressure. Youse your electric impact to give it a good
     shot.

     Since the other three lugs came off, try prying the wheel away from
     the hub cocking the wheel a bit. You'll probably need a
     piece of wood or something that won't damage the wheel. The idea is
     to put enough load on the studs that the hat on the back
     of the stud will bind against the axle flange "freezing" the stud
     and then the impact wrench will loosen the nut. This might
     take a bit of force and finesse, and several sets of hands.
     It's been some time since I've had mine apart, but if you can get
     the wheel off, you might be able to get a wire-feed or stick
     welder in there far enough to spot weld the stud and hold it in
     place until you want to change the studs.
     Good luck and don't swear too much!!
