Over high mileage, the factory universal joints wear down as internal grease paths dry up, resulting in a dangerous jerking or binding sensation in the steering wheel during tight maneuvers. Simultaneously, the large main knuckle seals and vacuum hub O-rings dry-rot, introducing a persistent vacuum leak that completely disables your dashboard-controlled automatic 4WD engagement system.\u003c\/p\u003e\n\u003cp data-path-to-node=\"9\"\u003eThis original equipment manufacturer (OEM) master service package supplies everything needed to properly overhaul both the driver and passenger side front steering knuckle stations simultaneously.
