Thanks! I'll give it a try tonight.
Edit: I ended up using a claw hammer in the manner you described to get leverage on the bolt and remove the shaft - it came out very easily that way.
I have the case separated from the clutch housing at this point and my JGY LSD part en route!
I would suggest that anyone attempting this also download the 2000 Sentra FSM from
www.phatg20.net - this is a superb write-up but it always helps to have a comprehensive reference.
Thanks again, Coalition.
