If still 'stuck' & don't want a tow…
try using the vehicle…
put the "nut removing" tool, on, add ya length of pipework, and position so end is on the ground..
then sit / jump on vehicle, suspension will compress & with a 200kg yank lard ass should crack it. prob rusted?
oh & make sure put some other nuts BACK on first, else bad things will happen as wheel falls off. putting other nuts back on will also change the tension on that last one. HTH
