Finally got it! I had the rear axle sitting on its own weight for a week using a lever as Jerry suggested; kept knocking at it with a sledge and used torch heat. I thought I saw a little movement so I put a wheel back on with the axle still jacked up; wrapped the tire with a long webbed pulling strap several times around like a yoyo; hooked a chain to the end of the strap; pulled it with another truck and it broke free! Thanks to all of you for your ideas and encouragement!
