Tips Wanted: Detach wheel from wheel hub

Hello, today wanted to change the brakes + discs with my 2001 Mondeo, but had to give up, because I absolutely did not get the rear wheels down -,- After simple hammer strokes had not been enough I started spraying the wheel pins + hub with WD40 (in the hope that it would eat a bit) also through the holes of the steel rims I tried to get behind the rim to the hub WD40. After e I lowered the vehicle weight on the wheels with the hope that something is going on here… After this has done absolutely nothing, I set the wheel nuts easily and wobbled back and forth in the driveway but also that didn’t do anything… Do you still have ideas that I can try?!!!!!! One page has already gone off completely, therefore a workshop visit remains out for the time being, had the problem already the mic h didn’t want to let the workshop go again… MfG Mopedcruiser
