The Timken SP450300 is a preset, pre-greased, and pre-sealed wheel hub unit bearing assembly. Timken engineers these hub assemblies to arrive ready for installation without requiring bench adjustment or field greasing - the preset load, lubricant fill, and seals are all handled at the factory. That design reduces installation variables and helps ensure consistent bearing performance at the wheel end. Sold individually by Pro Gear and Transmission. Call us to confirm this is the correct hub unit for your axle and vehicle application before ordering.
