Over high mileage, heavy towing, or water submersion, these small needle bearings lose their lubrication, leading to a distinct metal-on-metal squeaking or grinding noise from the front wheel ends. If ignored, a failing spindle bearing will rapidly score the outer stub shaft journal, requiring a costly shaft replacement. At the same time, the massive main knuckle seals and vacuum hub O-rings degrade, causing a vacuum drop that disables 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) master service package supplies all the mandatory small wear parts and primary seals to overhaul both front wheel stations simultaneously.
