I have an 04 Xterra and I need to replace the clutch. It has has the stock tranny rebuilt and I fear it may be having issues as well. I was looking around at some junkyards and I can get the 4wd tranny and parts for not much more then a new clutch. (Ok maybe like twice the price..) I am wondering how much modification any of that stuff needs to go into a 4 cylinder xterra, or am I crazy to even think of trying this???
