axle used in non-Rubicon Jeep JK models relies on correct pinion depth, bearing preload, backlash, and gear contact pattern for quiet operation and long service life. Suspension lifts, oversized tires, and increased driveline angles add stress to the carrier bearings, pinion bearings, and sealing surfaces.\u003c\/p\u003e\n\u003cp\u003eA master overhaul kit allows the major wear components and setup hardware to be replaced together instead of reusing old bearings, seals, shims, or one-time-use components.
