Maintain a reliable and leak-free drivetrain with this Genuine Nissan Gearbox Output Seal, designed specifically for Nissan Patrol GQ and GU models fitted with TB42, TB45, TD42, and ZD30 engines. This OEM rear output shaft seal is located at the back of the gearbox where it joins the transfer case, helping to retain transmission oil and prevent leaks from the output shaft area.

Over time, gearbox output seals can harden, wear, or become damaged due to heat cycles, driveline vibration, and age. A failing seal can lead to transmission oil leaks, low gearbox oil levels, contamination of surrounding components, and potential gearbox or transfer case damage if left unaddressed.

Manufactured to genuine Nissan specifications, this direct-fit replacement restores correct sealing between the gearbox and transfer case, ensuring long-term driveline reliability in both on-road and off-road conditions.
