Detailed Description

FAG SS4107 is a differential pinion seal engineered for rear driveline sealing where the pinion shaft passes through the axle housing. The Viton sealing material and auxiliary lip design help maintain contact at the sealing surface, while the metal and spring construction supports consistent fitment in the housing. This part is listed for 1972-1985 Jaguar XJ6, rear, and 1973-1979 and 1981-1985 Jaguar XJ12, rear, all noted without limited slip differential. The SS4107 is also referenced under FAG global number 413 4107 100.

This part cross-references SKF 29192 for the same application.

What It Helps Address

• Rear differential oil seepage at the pinion seal
• Contamination entering the pinion bearing area
• Loss of lubricant from the axle housing
• Wear-related sealing issues on Jaguar rear differentials
• Service replacement for aging pinion seals on Jaguar XJ6 and Jaguar XJ12

Installation Notes and Tips

Confirm axle configuration before ordering, since this seal is listed for rear applications without limited slip differential. Inspect the pinion yoke and sealing surface for wear, scoring, or corrosion before installation. Clean the housing bore thoroughly and verify the seal dimensions against the original part to ensure proper seating. For best results, install the seal squarely and avoid damaging the Viton lip during assembly.

Quality Assurance

FAG designs seals to meet vehicle manufacturer specifications and works with suppliers to maintain its quality standards. The SS4107 is built for demanding wheel-end and driveline sealing requirements, with materials selected to help protect internal components from dirt, dust, and moisture while retaining lubricant over service life.
