Keep your unitized wheel bearing held securely in the knuckle with the Timken Wheel Bearing Retaining Ring RET187. This clip is a direct-fit replacement for many vehicles, among them the 2006 Mercedes-Benz S350, 2000-2006 Mercedes-Benz S430 and 2000-2006 Mercedes-Benz S500. It is cataloged for both front and rear positions across these applications. See the Buyer's Guide tab for the full list and engine details.

  • Engineered to OEM specifications: built to the original specifications and aligned with Timken's quality standards.
  • Secure, bore-friendly fit: holds the bearing firmly without scoring the inside of the knuckle bore.
  • Universal design: needs fewer notch configurations, which simplifies installation.
  • Plier-ready notches: the notches are positioned for easy access with traditional snap ring pliers.

A retaining ring is the component that keeps a unitized bearing seated in its bore. When the original clip is missing, bent or distorted during service, this ring is intended to take its place. Consult the vehicle service information to find out whether the original ring may be reused during a bearing replacement.
