Abstract: The quiet drive of this invention provides for drive align imbalance and resulting drive align vibration and noise perceived by the vehicle occupants is overcome. The invention reduces imbalance in the system by establishing a theoretical center cylinder for the entire driveline components from the transmission or the transfer case if appropriate to the axle. Upon this theoretical centerline, each component is measured and controlled through unique design, machining and tolerancing to achieve an optimal minimum of driveline imbalance and resulting driveline vibration and noise perceived by the vehicle occupants.

Abstract: A wheel bearing (42) located between the wheel hub 14 and axle spindle (10) is supplied with lubricant located in an annular cavity between the hub and spindle. A lubricant seal (52) is fitted with slight interference between the hub and seal and defines a sealing lip (72), which is urged by a garter spring (70) into contact with an inner sleeve (76) of the seal. A slinger (58) is supported by tabs (88) on a surface of the bearing and provides a radial planar ring surface (86) located between the bearing race and seal. On assembly, the slinger provides a stop surface that limits axial movement of the inner sleeve of the seal toward the bearing.
