I bought a locking nut removal set, and it was 2 sockets but that didnt work cos on the outside of the nutt is a bit that freely spins so as the removal tool bit it was just spinning, so i chisled of the bit of the nutt the outer bit of the locking nutt, but now both the removal tools are now to big, so I hammered a socket (17mm) over it and then tried to remove but nope the fooker just slips off etc, do most garages have ways of getting these off? or is there summit else i can try?
