What is it they say? The memory is the first thing to go, thankfully the 2nd thing is still working perfectly.
Now that being said, I don't recall how the fork is attached to the shaft but I believe it was either threaded or pressed on and it may not be removable. I do know that to change the bump stop I had to totally disassemble the shock, remove the nut that holds the dampening plates on and then pull the shaft out of the shock body to get to the bump stop and that was an experience in itself.
