Locking Hubs: Description

The front driving axle hub locks are either automatically or manually actuated. When actuated, hub lock assembly locks hub, and wheel assembly to front drive axle.

When released, front drive axle is disengaged from hub assembly, and wheel assembly rotates freely on spindle. Two opposed tapered roller bearings allow hub and wheel assembly to rotate on spindle. A hub seal is installed behind inner bearing to prevent wheel bearing lubricant from contaminating brake pads and rotor surfaces.
