Cmon guys, go to harbor freight or other import place, by the $39.95 3/4 drive set with sliding bar. Use extensions to get it out away from outer wheel. Rest that extension and bar on a block of wood or stack for a pivot. Use a square tube lever about 3 or 4 ft long, slip it ALL the WAY onver handle. I, even have mine split to pass the handle joint some. NOW, use plenty of oils, bang on nuts and wheels some with fairly big mallet, and stand on the pipe over wrench set-up. BOunce a little, and SNAP! Either the nut loosens or wrench/socket breaks. My set has lifetime replacement, even in IMport kind. Might try using a big die to clean threads of studs first too to help ease off once started!
Work on this all afternoon, with a few beers, and you'll be a growly animal, wanting to rip some one's head off! Ain't this fun??
