I have been looking at buying a new used (2000 to 2001) Xj for a daily driver / weekend warrior. Will be running 31 to 33's on a 5.5" lift. I think I would like an automatic this time. Questions....(1.) Is the AW4 a good tranny ? (2.) Will the rear dana 35 or 8.25 hold up. I know you could install a super axle kit but is that good enough ?? (3.) Low front pinion dana 30..... is it junk ? I know i can pick up a high pinion 30 for $ 100 bucks or less for a swap out. (4.) Did the optional towing package get you a larger radiator and tranny cooler ? (5.) What Xfercase is better 242 or 231 ? Every time I call on a low mile XJ some one has beaten me to it. Last Question........... I have found a real nice 2000 XJ, http://sfbay.craigslist.org/sfc/car/561715519.html 102,000 miles for $ 3999, one owner, garaged kept, no scratches or dings. Like new inside and out,its super nice but is a 4x2. How easy is this to convert to a 4X4 ?? I do have skills but have never converted a 4X2 into a 4X4 . Any one who had done this conversion feel free to chime in. Any and all opinions welcome. Thanks , Rick
