Over high mileage, or following a sudden universal joint failure, the axle shaft's yoke ears can bend, stretch, or crack, preventing the U-joint snap rings from seating safely and threatening a total hub failure. Concurrently, removing the outer axle assembly destroys the massive main knuckle seal, which is a single-use component responsible for sustaining the vacuum required to trigger your dashboard-controlled Electronic Shift-on-the-Fly (ESOF) automatic locking hubs.\u003c\/p\u003e\n\u003cp data-path-to-node=\"9\"\u003eThis original equipment manufacturer (OEM) combination service package provides a factory-correct solution to overhaul one front steering knuckle station.
