Just bought another xj with 8in lift and 35's. It has 4.56 gears but the guy said the pinion broke some teeth in the front axle. He gave me a new set of ring and pinion. I Just ordered a dial indicator a gear installation kit and a inch lb torque wrench. Was going to try to do it myself not because I can't afford someone to do it just because that's the only thing I've never messed with on a cherokee and would like to learn to do it. I've been looking online but would like to know if anyone has a good website that goes thru this process. Its not my daily driver so I have all the time in the world to do it right. Thanx.
