Detailed Description

Timken 512218 is a direct-fit rear hub assembly for 2000-2005 Toyota Celica, 2003-2008 Toyota Corolla, 2003-2008 Toyota Matrix, and 2003-2008 Pontiac Vibe. The assembly uses precision internal geometry and controlled surface finishes to support smooth rotation, lower runout, and consistent wheel-end operation. For shoppers searching for a rear wheel bearing and hub assembly for Toyota Corolla rear or Pontiac Vibe rear service, Timken 512218 provides the dimensional accuracy needed for proper fitment.

Timken’s sealing design includes a reinforced outer case, ribbed rubber inner diameter, contamination exclusion features, and vent holes to help protect the seal during installation and maintain sealing performance. The integrated ABS sensor is tested to monitor wheel speed for anti-lock braking systems, making this part a practical choice when replacing a worn rear hub on a Toyota Matrix, Corolla, Celica, or Pontiac Vibe.

This part cross-references SKF BR930329 for the same application.

What It Helps Fix

• Rear wheel noise or humming from a worn hub bearing
• Excessive wheel-end vibration or runout
• ABS wheel-speed signal faults related to the hub assembly
• Uneven braking feel caused by hub wear
• Loose or rough rear wheel rotation

Installation Notes and Tips

Verify rear position, bolt pattern, and pilot dimensions before installation. Clean the mounting surface thoroughly and inspect the knuckle, axle area, and brake components for wear or damage before installing Timken 512218. Confirm ABS connector routing and sensor alignment during assembly to avoid signal issues after service.

Quality Assurance

Timken manufactures hub bearing assemblies using OE-developed test procedures that control design, materials, and production processes. That approach supports consistent performance, dimensional accuracy, and long-term wheel-end reliability.
