Over high mileage, heavy towing, or exposure to harsh road conditions, the massive main knuckle seals and vacuum hub face O-rings naturally dry-rot, crack, or lose their tension. This introduces an immediate vacuum leak that leaves your automatic 4WD system unable to lock in. At the same time, the outer axle shaft dust seals decompose, leaving a gap that permits abrasive trail mud, moisture, and road grit to penetrate your front axle housing tubes and accelerate inner component wear.\u003c\/p\u003e\n\u003cp data-path-to-node=\"9\"\u003eThis original equipment manufacturer (OEM) master service kit provides a factory-correct solution to overhaul both the driver and passenger side front steering knuckle stations simultaneously.
