Great bit of info here and finally found out why there are two circlip grooves..

"Note there are 2 groove on the axle. The circlip will fit into that groove. The inside groove is used when you have auto hubs and the groove near the end of the axle is used when you have manual hubs."
I had just pulled the drivers side apart - first time since we have had the vehicle and it has manual hubs and the previous person who pulled it apart had put the circlip in the auto hub groove.
What I would like to know it how do you dismantle the manual hub. The manual shows a circlip...but where?
