Abstract
An apparatus for a vehicle is provided that has an axle and a spindle sleeve with a spindle sleeve inner surface axis coaxial with the axis of the axle, and a spindle sleeve outer surface axis not coaxial with the axis of the axle. A hub has an axis coaxial with the spindle sleeve outer surface axis, and the hub at least partially defines a chamber. First and second ports extend through a wall of the hub to the chamber. The hub rotates about the spindle sleeve through the aid of two bearings. Lubricant is present within the chamber, and the first port provides a pathway for a pressurized fluid to be introduced into the chamber to force the lubricant out of the chamber via the second port.
