MOOG 513179 Wheel Bearing and Hub Assembly Ensures proper ABS function and quiet operation Quad-lip seal provides maximum contamination protection Precision-matched components deliver smooth and quiet operation Integral raceway provides proper clearance between the ball and bearing riding surfaces Improved connection and conductivity of the ABS signal due to high strength polymer and copper wiring Bears vehicles weight Lubricated, sealed and complete with hub assembly Provides tight fit to the wheels and transmit power without slip Innovative roll form design ensures consistent and optimal preload. In specific applications, the molded ABS shield and socket connections are used to provide the optimal defense against contamination, providing longer life. Manufactured from a blended material that provides superior ABS protection, increases abrasion resistance and protects against adverse conditions. Premium quad lip design seal ensures maximum protection. Rigorously controlled manufacturing processes ensure exact matching of bearing raceways and rolling elements to consistently deliver superior performance and minimize noise and vibration. Wheel studs feature a protective coating that helps prevent rust and corrosion, allowing easier removal and proper torquing of the wheel nut.
