sounds like you are missing the flat, splined washer. it is supposed to go between the
circlip (snapring, whatever you want to call it that goes aroung the axleshaft) and the spindle. This thread pictures the washer and circlip in the first post. Push the shaft out from the back of the steering knuckle, should be just hand pressure to make it come out enough to put the washer and circlip on...
