Common Problems It Can Help Address

• Rear wheel bearing noise or growling
• Wheel-end vibration at speed
• Excessive hub runout affecting braking feel
• ABS wheel speed signal issues from a failing sensor
• Contamination-related bearing wear

Installation Notes and Tips

Verify rear position and vehicle configuration before ordering, especially on Oldsmobile Calais and Cutlass Calais models with Stabilizer Bar notes. Inspect the knuckle, axle area, and mounting surfaces for wear or damage before installation. Confirm ABS connector routing and sensor alignment during replacement.

Quality Assurance

Timken applies OE-developed testing to its hub bearing assemblies and 100% tests the ABS sensors used in these units. The sealed bearing design, reinforced seal construction, and precision internal geometry are used to support consistent performance in daily driving.
