Hi. I recently bought a 2001 Jeep Cherokee 4X4, 4 door, Sport and need to rebuild the front axle and differential. The front is a Dana 30 with a low pinion, but I am having issues determining which kit to order differential rebuild. I have no idea if my differential is Standard or Reverse Rotation and if it requires a Crush Sleeve. I looked up the parts on RockAuto.com which provides the list below. I do not have experience rebuilding a Jeep differential. Could someone provide me some guidance, please?
Thanks!
