Detailed Description

On 2001-2008 Ford Focus applications, this seal helps protect bearing components from dirt, dust, and moisture while helping maintain grease inside the assembly.

What This Wheel Seal Helps Address

• Grease loss at the wheel bearing area
• Contamination from road dirt, dust, and moisture
• Premature wear caused by compromised wheel-end sealing
• Noise or roughness associated with a failing rear inner seal
• Service replacement needs on Ford Focus rear wheel-end assemblies

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.
