Bit of a brutal fix this one, those stupid internal circlips on PSA rear hubs with no lugs for circlip pliers,I have killed Snap-on pick sets trying to do these.My cure which works every time is to use Oxy-acet to heat up the end of the clip it can then be bent out with a cotter pin removal tool so you can remove the bl**dy thing !

Be interested to see others methods??
