Installation Notes and Tips
Verify the seal dimensions, wheel-end position, and vehicle application before installation. The FAG SS3924 is specified for the rear inner location on 2001-2008 Ford Focus models, so matching the bore diameter, outside diameter, and seal width is important for proper fitment. Inspect the hub, bearing surfaces, and sealing surfaces for wear or damage before installing the new seal.
Quality Assurance
