Lockout hub basics
Lockout hubs let the front wheels disconnect from the axle so the front driveline is not turning during two-wheel drive use. Reduced drag can help the drivetrain run quieter on pavement and keeps the front driveshaft from spinning when it is not needed. Hubs with a nylon knob are often chosen where a lighter feel at the dial is preferred.
Before buying, match the hub to the axle type and the spline count. Mismatched hubs can bind, slip or refuse to lock, so inspect the axle splines for wear. Replace the gasket whenever the hub is removed to keep water and grit out of the bearings.
Care is simple. Keep the hub clean, check that the knob turns freely, and lubricate the moving parts with a lubricant suited to your hub type. Signs of trouble include grinding, a hub that will not engage, or water inside the housing. Inspect the seals and splines together during routine service.
