> John, most auto parts stores (real auto stores) will have a 2 1/8" socket,
sometimes they are a bit pricy thought - might try one that caters to
pickups and trucks.   What I suggest is to get a plus 700 lb-ft air wrench
(borrow or rent - a smaller one may do, but most with a 1/2" socket are too
weak).  It will spin the nut off in 3 beats and you dont' have to anchor the
motor, the motor's inertia is sufficient to counteract the torque with an
air wrench.

One more tip on this.  Install nut firmly with hand wrench as tight as practical (~ 100 ft lbs)  then use impact wrench to turn nut ONE side (1/6 turn). Make mark on socket & counterweight so you can watch this happen  This is real close to 350 ft lbs.
