> 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.
