This part cross-references MOOG Hub Assemblies 513289 and SKF BR930778 for the same application.

What It Helps Solve

• Wheel bearing noise from worn or rough hub components
• Excess wheel-end vibration or runout
• ABS warning light concerns tied to wheel-speed signal issues
• Loose or inconsistent hub operation at the wheel end
• Brake feel changes related to hub instability

Installation Notes and Tips

Verify the vehicle position before ordering: Fits 2010-2016 Cadillac SRX, front; Fits 2010-2016 Cadillac SRX, rear; Fits 2011 Saab 9-4X, front; Fits 2011 Saab 9-4X, rear. Confirm spline count, bolt circle, flange offset, and pilot diameters against the original hub before installation. Clean the mounting surface thoroughly and inspect related suspension and brake components for wear that could affect hub performance.

Quality Assurance

Timken manufactures hub bearing assemblies using OE-developed test procedures and controlled design, material, and process standards. The ABS sensor is fully tested to monitor wheel speed for anti-lock braking system operation, and the seal and bearing construction are engineered to support long-term wheel-end reliability.
