Key Features

• Part number SS5583 for direct reference and ordering
• Polyacrylate sealing material for demanding driveline service
• Rubber, spring, and auxiliary lip seal type
• 2.953 in bore diameter and 2.962 in outside diameter
• 1.575 in seal width for the listed application dimensions

Detailed Description

This FAG differential pinion seal is engineered to help protect driveline components from dirt, dust, and moisture while retaining gear oil at the pinion area. The seal dimensions and construction are specified for exact-fit applications, including Nissan Frontier, Nissan Pathfinder, Nissan Xterra, Nissan Armada, Nissan GT-R, INFINITI Q50, INFINITI QX60, and related models listed below. If you are replacing a leaking pinion seal on a Nissan Frontier or INFINITI QX56, SS5583 provides the correct style and sizing for the application.

This part cross-references Quality-Built 15886 for the same application.

• Helps keep road debris, dust, and moisture out of the driveline
• Addresses noise or contamination concerns tied to seal failure
• Supports maintenance on front and rear differential service jobs

Installation Notes and Tips

Verify bore diameter, outside diameter, and seal width before installation to confirm the correct match for your axle or differential housing. Inspect the pinion surface for wear, scoring, or corrosion before pressing in the new seal, and replace any damaged mating components as needed. Clean the sealing area thoroughly so the auxiliary lip can seat properly and maintain consistent contact.

Quality Assurance

FAG designs seals to meet vehicle manufacturer specifications and works with suppliers to maintain its quality standards. The seal construction is selected to protect wheel-end and driveline components from contamination and grease or lubricant loss over the service life of the bearing or seal assembly.
