use a spanner
put a bit of pipe on the spanner
get osmeone else to apply gentle force to the spanner
don't hang off it like a gorilla
using a soft drift, tap the nut with a hammer
the shock "should" ease it off
make sure you use a 6 sized spanner if possible as there is less chance of it rounding the nut off
failing that, you would always weld a bit of bar to the nut once it becomes so mangled you can't so anything with it
rememebr to replace the nylon washer when you get a new one
