FAG SS3771 Wheel Seal - Front or Rear

FAG SS3771 Wheel Seal Overview

FAG SS3771 is a metal wheel seal with nitrile sealing material, built for wheel end service where contamination control and grease retention matter. With a 2.562 in bore diameter, 2.566 in outside diameter, and 1.813 in width, this seal is sized for precise wheel-end sealing in applications that call for this specification.

For drivers searching for a wheel seal for Honda Civic or Toyota Corolla service, FAG SS3771 is a technical replacement option that follows the dimensional requirements of the application. The SS3771 part number is also referenced by Bosch 18050 and National 203006 for the same application.

Key Features

• Metal seal type for durable wheel-end sealing performance
• Nitrile sealing material for resistance to dirt, dust, and moisture intrusion
• 2.562 in bore diameter for application-specific fitment
• 2.566 in seal outside diameter for controlled housing engagement
• 1.813 in seal width for the specified wheel end design
• Engineered to help retain grease and protect bearing components
• FAG SS3771 wheel seal for service work requiring exact dimensional matching

Detailed Description

FAG SS3771 is a wheel seal designed around manufacturer-level dimensional requirements rather than a universal fit. The metal seal construction and nitrile sealing element are selected to help keep contaminants out of the wheel end while supporting grease retention over the life of the bearing. Because wheel seal specifications vary by vehicle class, position, and application, SS3771 should be matched to the exact bore, outside diameter, and width required by the vehicle.

For technicians and parts buyers looking up Honda Civic wheel seal or Toyota Corolla wheel seal applications, the SS3771 part number provides a focused OE-style replacement reference. This part cross-references Bosch 18050 and National 203006 for the same application.

What It Helps Address

• Wheel end contamination from dirt, dust, and road moisture
• Grease loss at the bearing seal area
• Wear caused by compromised wheel seal integrity
• Service issues tied to incorrect seal dimensions
• Replacement needs for wheel-end sealing maintenance

Installation Notes and Tips

Confirm the required bore diameter, seal outside diameter, and seal width before installation. Wheel seals must be installed in the correct position and seated evenly to avoid leakage or premature wear. Clean the hub and bearing area thoroughly before assembly, and inspect the mating surfaces for damage or scoring that could affect sealing performance. Always verify the application by vehicle year, make, model, and wheel-end specification before ordering FAG SS3771.

Quality Assurance

FAG designs wheel seals to meet vehicle manufacturer specifications and works with suppliers to maintain FAG quality standards. SS3771 is built for demanding wheel-end sealing requirements where precise fit and material selection are critical.
