suburpy

Just bought a 81 wagon to do up. Needs both front axles replaced, but the key tool for the mag lock nuts has burred and wont undo the lock nuts. Have drenched the nuts in the Southern hempisphere supply of CRC/ WD-40. Tried banging an old socket and undoing them, just broke the socket! Tried cold chisel to move them but will no budge. What now - cant remove the axles without removing wheels. Any Ideas
