Tried to remove the cush rubbers today as I am going to have the wheels powder coated... the rubbers were good, so I didn't want to destroy them. You can't knock them out as the drift just bounces off the rubber, and there is no way to get to the outer sleeve... So I made this puller, that has a split threaded cotter. its a bit fiddly, but they came out a treat, and I can re use them now
