What It Helps Address

• Transmission fluid seepage at the shaft seal area
• Contamination entering the transmission through a worn seal
• Leak-related fluid loss during drivetrain service
• Seal wear from age, heat, and mileage
• Replacement needs during rear transmission maintenance on Toyota and Lexus vehicles

Installation Notes and Tips

Verify shaft diameter, outside diameter, and width before installation to confirm the seal matches the housing and shaft dimensions. Inspect the sealing surface and surrounding components for wear, scoring, or contamination before pressing in the new seal. Clean the bore thoroughly and install the seal squarely to avoid distortion or premature leakage. Confirm the vehicle-specific rear application listed for your Toyota 4Runner, Tacoma, Tundra, Sequoia, FJ Cruiser, or Lexus GX models before ordering.
