Detailed Product Overview

FAG SR3516 is a differential pinion repair sleeve used to renew sealing surfaces on shafts that have been damaged by wear or leakage. Its precision fit and stainless steel construction make it a practical repair solution for driveline and axle service, especially when the original shaft surface is no longer sealing correctly. This part number, SR3516, is listed for a wide range of rear-position applications across Chevrolet Silverado, GMC Sierra, and select Nissan X-Trail models.

Confirmed fitment includes 2010-2012 Nissan X-Trail, rear applications on 2001-2007 Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD, and rear applications on 1988-1997 Chevrolet C2500, K2500, and related GMC full-size truck platforms. It also appears in transfer case and rear driveline service listings for Chevrolet Silverado 1500, Silverado 3500, GMC Sierra 1500, Sierra 3500, and Dodge Ram 2500/Ram 3500 applications where the 2.205 in. shaft specification is required.

What It Helps Repair

• Oil leakage at a worn shaft sealing surface
• Grooving or scoring on the pinion or shaft contact area
• Premature seal wear caused by surface damage
• Reduced service life from repeated seal failure
• Costly shaft replacement when the base shaft is still serviceable

Installation Notes and Tips

Install the sleeve only on shafts that match the listed 2.205 in. diameter specification. The repair sleeve is designed to be installed without shaft removal or machining, which helps reduce downtime during driveline repair. Verify the shaft diameter, flange diameter, and installation depth before assembly, and confirm the vehicle-specific rear or N/A fitment notes for your application. For search relevance, this part is commonly requested for Chevrolet Silverado rear seal repair, GMC Sierra rear driveline service, and Nissan X-Trail differential pinion repair.

Quality Assurance

FAG manufactures this repair sleeve as a precision sealing component using heat-treated stainless steel to support long-term service in demanding driveline environments. The SR3516 is engineered to restore the sealing surface rather than replace the shaft, providing a straightforward repair path for worn components.
