This might be a stupid question but I am by no means jeep savvy. I want to upgrade the gears to 4.56 gears for my rear Dana 35 axle so the 33's I hope to get wont slow me down too much. My question is, do I only replace the two rear gears or do i replace the front ones as well? Or do I leave the front ones 3.73? Also, should I replace the axles? If so, do I replace the front ones as well as the back? Thanks!!
