Maybe I'm wrong and there is a lockwasher, but I'm pretty sure there isn't, and mine was hell to get off.
I use the lock washer on pitman arms as a spacer to stop the possibility of the nut bottoming out on the shoulder at the base of the threads where the splines stop.
I would be just as comfortable with a machined spacer and loctite or an upset locknut.
I've not seen a stock pitman on a stock steering gear without a lockwasher done that way on purpose.
Do you have a drop pitman arm?
