Seal and Seal Assembly Abstract A seal has a body, a leg and first and second sealing areas. The seal is used in a seal assembly having first and second members such as, for example, a frame portion and steering knuckle of a work vehicle. Apparatus such as a bearing supports the knuckle in rotation relative to a king pin of the frame portion. Foreign matter can enter between the frame portion and steering knuckle and interfere with vehicle steering. In the assembly, the sealing surfaces contact substan- tially perpendicular surfaces of the frame portion to block passage of foreign matter to the bearing. A second end portion of the seal leg can be controllably deflectable in order to permit overfill of lubricant to pass from the bearing cavity between the frame portion and steering knuckle.
