My Brother-in-law has a 69 c-10 chevy LWB that he has owned since 1970. He parke the truck a couple of years ago and the drivers side rear went flat. Will not hold air so he has tried to remove the wheel to get the flat repaired. However, the wheel is apparantly rusted to the hub. He has tried saturating with WD-40 and has even bumped and tried lifting the wheel with his front end loader but wheel wont' budge. Any ideas how he might remove the wheel?

Thanks,

Robert
