You say front drive shaft, do you mean the front axle shaft, or the short shaft
between the engine and trans? anyway, the center t-case mount unbolts, I would
drop the drive shafts and remove the t-case, they aren't hard or heavy and it will
give you working room, then pull the tranny and swap out that clutch, your biggest
problem will be making sure the clutch disc is centered so the trans will re-mate with
engine easily, I would get a centering tool or a socket that fits good to center the
disc just before the pressure plate gets tightened down.
This isn't a hard fix, but could take half of your day not being home
Good Luck
