What This Seal Helps Address

• Transmission fluid seepage at the seal interface
• Contamination entry from dirt, dust, and moisture
• Loss of sealing tension from worn or aged components
• Fitment issues when replacing a vehicle-specific transmission seal
• Service concerns on rear-position applications with long boot notes

Installation Notes and Tips

Verify the year, make, model, and position against the vehicle listing before installation. Several applications are listed with rear position and long boot notes, so confirm the transmission configuration and seal dimensions before ordering. Clean the sealing surface thoroughly and inspect the bore and mating components for wear, scoring, or contamination before installing the new seal.

For best results, match the part number SS2666 to the vehicle application and confirm any notes shown for the specific Ford, Lincoln, or Mercury model. This helps ensure the seal seats correctly and performs as intended in service.

Quality Assurance

FAG designs seals using high-quality materials and works with suppliers to meet manufacturer-specific requirements. The sealing design is intended to protect wheel-end and drivetrain components from contamination while helping retain grease or fluid over the service life of the bearing or seal assembly.
