Ya, gotta love used car dealers.

Giving up for the day, buying an air compressor and impact wrench tomorrow.
Tried removing the hub nut with a 12 foot breaker bar, no joy. Bent a tire iron and 2 lug bolts trying to get it off with the vehicle lifted and wheel locked against the ground with the tire iron. Then put the tire back on so I'd have the weight of the vehicle to resist against and blew apart the gears on my 1/2in socket (lifetime guarantee, here I come).
Tomorrow's payday, time to finally upgrade to the wonderful world of air tools.
