Clutches are easy if you have any mechanical abilty.The toughest thing, if it's 4x4 is getting the transfer case unbolted and set down.A good transmission jack is a must here.Im the old days when I was a little harder pressed for money than I am now I have changed clutches with scissor jacks and hydraulic jacks but it is tough and kind of dangerous with a tranny as heavy as the Nv.The actual mechanics of it is very simple.Be sure to resurface the flywheel while you're in there and its a good idea to replace the input shaft bearing.
