Working on a 1993 XJ I picked up and have been slowly 'restoring'. From the factory it's a 3.07 ratio. While replacing the bearings and seals on the front axle (Dana 30) I counted the ring and pinion teeth and got a 3.55 ratio. I was pleasantly surprised since I wanted to regear to at least 3.55 or 3.73 for better drivability (I don't do a ton of off roading). Finally started working the rear axle and when I popped the cover saw "3 0 7" stamped on the ring gear. Counted the teeth and sure enough it's a 3.07 ratio. Double checked the front axle (since it's buttoned up) by rotating the hub and counting the yoke and it's definitely at 3.55. Is there something I'm missing here - pretty positive you can't run 4WD with mismatched gear ratios....
