• Rough rotation caused by worn bearing surfaces
• Seal wear that can allow lubricant loss and contamination
• Service intervals that call for a sealed, maintenance-free bearing unit

Installation Notes and Tips

Confirm the rear position and verify dimensions before installation. Match the bearing to the vehicle application exactly, especially on BMW 525i rear wheel bearing and Pontiac GTO rear wheel bearing jobs where hub and bearing specifications must align. Inspect the surrounding hub, seals, and mounting surfaces for wear or damage before assembly, and follow the vehicle service procedure for proper press-fit or hub installation.
