Samurai or sidekick?, if it is the sidekick, it has a "lock plate" of sorts that has 4 phillips head screws that thread into the actual lock nut. The lock nut itself has the 4 notches in it for the special socket to go into, or if you don't have one, a chisel will work as well. I cant remember if it is reverse threaded or not though. I should as I had mine apart enough times
