Will this remove a stuck wheel nut on a boat trailer?
The challenge is that there is no weight on the wheel so a lever does no work - it just turns the whole wheel. Or if this will not do the job, any ideas as to what will?
an air wrench if all else fails, try putting some gentle heat on the nut and then cooling it quickly - co2 extinguisher or very cold water. Plus gas is very good too, hard to find these days though.
