Mhopper, it's no major issue. Did mine a couple months ago and also changed out the u-joint vs. changing the drive shaft. Drop the exhaust, pull the heat shield, and unbolt (4) ujoint bolts at differntial, (4) bolts at transmission, and (2) nuts at the carrier bearing. Be carefull to match mark the driveshaft before separating it and check the center u-joint while you have it that far apart. The most difficult part for me was getting the old bearing off the shaft. I ended up cutting mine off since I had a complete new carrier ready to go on. BTW, when I get a chance I'll upload you the photo of all the "skins" I found in my rear console. LOL Glad to hear there is another reptile based speed buggy out there. LOL
