its not that hard, ive not done it on my kj, but ive done it to my bro's cherokee and our grand. Its kind of like changing the oil in the rear end. u take a bunch of bolts off, knock it loose with a rubber mallet and it falls and oil goes everywhere. lol jk. i usually leave 2 or 3 bolts loosely in so when it does break loose it dosent fall. then i slowly take the rest out leaving one in an end so i can slowly lower it by taking that last bolt out. After u get the pan off, i believe the libby has a filter, u change it and clean ur pan up really good. clean the magnet and all that, then put ur new gasket on. The gasket and filter come in a pack that u can get at any advance auto parts store, or autozone. Some ppl will put alittle rtv on before the gasket so that it stays in place and seals alittle better. bolt it on making sure the gasket is all lined up and crap and tighten all 1 million or so of ur bolts. The oil goes in through the dip stick if u didnt know, im not sure how much. i believe its 4 quarts or something like that????
