on hubs that are really stuck you need the heavy duty 3 arm puller,it weighs about 20 pounds, put it on tighten lug nuts tight, turn the shaft down to the axle, get a 3 or 4 pound hammer and beat the cross bar till it wont turn any more, heat hub if you want, stand to one side when working with the puller some times when the hub releases every thing will fly backwards, dont be in its way, use eye protection, pieces of metal can fly off the cross bar, after you have gotten the cross bar as tight as you can, walk away for an hour or so, come back and beat on the crossbar somme more, it might take several times doing that but it will come lose, leave the puller on over nite, it might pop off , if not just keep tightening the cross bar on the puller till the hub pops off, any one can gorilla some thing off, it takes a good mechanic to do a job right,anyone can drive a car, but only the good guys can build one
