FAG SS2838 Differential Pinion Seal - Rear

Rear Differential Pinion Seal for Toyota and Lexus

FAG SS2838 is a rear differential pinion seal built for Toyota and Lexus driveline applications that require precise sealing at the pinion area. It uses a metal case, spring, and auxiliary lip design with polyacrylate sealing material to help keep gear oil contained while blocking dirt, dust, and moisture.

With OE-style dimensions and application-specific fitment, SS2838 is a direct replacement choice for rear axle service on vehicles such as the Toyota Tacoma, Toyota Tundra, and Lexus GS300.

Common Problems This Seal Can Address

• Rear differential gear oil leakage at the pinion area
• Contamination from dirt, dust, or moisture entering the seal area
• Oil seepage that can leave residue around the rear axle housing
• Seal wear from age, heat, and driveline use
• Noise or driveline service concerns tied to low differential fluid level

Installation Notes and Tips

Confirm the vehicle’s rear axle application before ordering, especially on 2006-2013 and 1995-2004 Toyota Tacoma models that note use without a locking differential. Verify bore diameter, outside diameter, and seal width against the original part before installation. Clean the sealing surface thoroughly and inspect the pinion yoke and housing for wear or damage that could affect sealing performance.

For Toyota Tacoma, Toyota Tundra, and Lexus rear differential service, proper alignment during installation is important to help the seal seat evenly and maintain contact with the rotating surface.

Quality Assurance

FAG seals are produced to meet vehicle manufacturer specifications using materials selected for demanding wheel-end and driveline sealing requirements. The SS2838 follows application-specific dimensions and sealing construction intended for consistent rear differential service on the listed Toyota and Lexus vehicles.
