The Timken SP550104 is a wheel hub unit bearing assembly designed as a preset, pre-greased, and pre-sealed unit. Timken engineers this hub assembly so the bearing preload is factory-set, the grease pack is applied at the factory, and the seals are installed before shipment - eliminating those setup steps at installation. Sold individually, this is a genuine Timken part available from Pro Gear and Transmission. Call us to confirm proper fitment for your axle application before ordering.
