The rear hub is supported or floats on the axle spindle on 2 opposing tapered roller bearings. A rear hub seal is installed behind the inner rear wheel bearing to prevent rear axle lubricant from leaking onto the rotor. The rear hub is retained on the spindle by a ratcheting hub nut tabbed to a slot on the spindle.
The rear wheel bearings are packed with a lithium-based grease, premium long-life grease, to provide initial lubrication until axle lubricant flows into the rear hubs and the inner rear wheel bearings during vehicle operation.
