How do you replace a jeep internal slave cylinder?

Oh JOY! So you must have a Jeep somewhere between 1987 & 1992 or 3 (I forget which year they moved the internal slave outside). Basically pull the Xfer case & transmission & bell housing so it can be accessed. Might as well think about a new clutch while you are in there too. It ain't fun! A poor design by someone out of touch with reality!
