If you are talking about the spacer, washer, that may or may not go between the clip and the hub flange then it all depends upon the play in the shaft, ,drive shaft end play,. The factory specifications should be between .08 to 0.25 MM. They have different thickness sized washers depending upon how much play you have in the shaft. I would guess that the play would depend upon the wear of the components and how stuff fits together. If the lock washer wasn't bent back then it is a good thing that you are taking care of it now.
