Anyone know how to get this circlip off the input shaft into the transfer case on a JK. It does not have holes for standard circlip pliers to attach to. I can get it partially open then get screwdrivers behind it but it does not want to come out of the slot all the way. There is possibly a special tool required. Might just take the TC half to a transmission store and get them to undo it. I am talking about the one that sits behind the input seal.
