from what i am seeing it came on some models with v8, and with 4.0 with the towing package. I've already installed a factory hitch, with reese wiring as opposed to dealer, and i have a tranny cooler. Seeing as I drive where its hilly and curvy and i tow, I figured 3.73 would be good and it'd finish off the "tow package". I smoked a curb that they poured the year chills for cheo was at dave's house, for the last year or two the rear end got worse n worse. The rear i bought from a wrecker(garage louis guay). I called them to see if they have the front but they dont. A&O site says they have none in stock but i am sure they'd find one quick if i called. I'd go for a whole diff if i can. or used gears, or new gears, or maybe just put my 3.55 back in the rear. I am driving with the front shaft off for now(awd). If they're the same as TJ gears they should be pretty common, im sure someone has a set laying around somewhere after going to 4:10 or 4:56.
