What It Helps Solve

• Wheel bearing noise such as growling or rumbling
• Excessive wheel play caused by worn bearing surfaces
• Uneven wheel-end rotation from damaged rollers or races
• Heat buildup from bearing wear or contamination
• Service issues during hub, spindle, or axle bearing replacement

Installation Notes and Tips

Confirm the bearing dimensions against the hub, spindle, and race specifications before installation. Clean and inspect the mating surfaces, replace worn races as required by the application, and pack or lubricate the bearing according to the vehicle service procedure. Proper preload and torque settings are important for wheel bearing life and quiet operation. Verify the vehicle application by year, make, model, and position before ordering; this part number, B31, is often used in wheel bearing searches for Ford, Chevrolet, and Dodge service needs.
