The Timken HA590999 is a hub unit bearing assembly in Timken's preset, pre-greased and pre-sealed form. Preset means the bearing setting is already made at the factory, and pre-greased and pre-sealed mean the unit comes lubricated and sealed, so the wheel end goes back together as a complete unit.
This is a genuine Timken part from Pro Gear and Transmission. Hub units are specific to the axle and wheel end they were built for, so call us with your application details to confirm proper fit before you order.
