FAG SR3476 Differential Pinion Repair Sleeve

Precision Repair Sleeve for Differential Sealing

The FAG SR3476 differential pinion repair sleeve is a precision stainless-steel sleeve used to restore sealing performance on worn or damaged shaft surfaces. It is a practical repair solution for driveline service when the shaft surface has wear marks that can affect seal contact.

Built from heat-treated stainless steel, the SR3476 helps extend shaft service life and reduce premature wear without requiring shaft removal or machining. That makes it a direct-fit repair approach for many Subaru, Toyota, Lexus, and Jeep applications where pinion or shaft sealing is critical.

Key Features

• Precision repair sleeve for damaged shaft sealing surfaces
• Heat-treated stainless steel construction
• Helps improve seal contact and reduce leakage at worn areas
• No shaft removal or machining required for installation
• Cost-effective alternative to replacing a serviceable shaft
• Part number: SR3476

Detailed Product Overview

The FAG SR3476 is engineered to provide additional sealing where a shaft has been scored, grooved, or worn by repeated seal contact. Its stainless-steel construction and precise dimensions support a clean repair on driveline components, helping maintain proper sealing performance on affected differential pinion and shaft surfaces. This part cross-references Dorman - HELP 99147 for the same application.

Compatible fitment includes many vehicles such as 2001-2014 Toyota Highlander, rear; 2003-2014 Toyota Sienna, rear; 2004-2011 Saab 9-3, front; and 2008-2014 Subaru Tribeca. The SR3476 also appears across a wide range of Toyota Corolla, RAV4, Tacoma, Tundra, Lexus RX330, and Jeep Cherokee applications, making it a useful service part for import and domestic driveline repair work.

Common Problems This Part Can Address

• Oil seepage at a worn shaft sealing surface
• Seal failure caused by grooves or scoring on the shaft
• Premature wear from repeated seal contact
• Need for a repair without replacing the shaft
• Driveline service issues on differential pinion sealing surfaces

Installation Notes and Tips

Measure the shaft before installation to confirm the sleeve dimensions match the repair area. The listed dimensions are 1.496 in shaft diameter, 1.781 in flange diameter, 0.669 in overall width, 0.512 in width on shaft, and 0.984 in installation depth. Clean the shaft surface thoroughly before installing the sleeve so the sealing surface seats evenly.

For fitment verification, use the vehicle-specific notes in the catalog. Examples include Fits 2001-2014 Toyota Highlander, rear; Fits 2004-2006 Lexus RX330, rear; and Fits 1987-2001 Jeep Cherokee, front or rear depending on application.

Quality Assurance

FAG is known for precision-engineered drivetrain and sealing components, and the SR3476 is manufactured as a heat-treated stainless-steel repair sleeve for consistent fit and sealing support. Its design focuses on restoring the sealing surface rather than replacing the entire shaft, which helps reduce repair complexity while maintaining service quality.
