I am rebuilding my spare 3-speed transfer case. There is some wear of the "dog teeth" on the high speed gear. The clutch sleeve mates to these teeth and then onto the output shaft. My question is: how much wear is too much? I can't find anything in Haynes or the factory service manual to tell me what the wear limits are. The movement is less than one degree of rotatation, and the dog teeth are only worn on one edge. Sorry if the words don't make sense -- I tried a photo but it did not turn out too well.
