Protect your front differential from oil leaks and contamination with this Genuine Nissan Front Differential Pinion Seal, designed to suit late model Nissan Patrol GQ and GU vehicles fitted with the H233 front differential (built after 10/1991). This OEM seal is fitted where the front tailshaft connects to the differential pinion flange, preventing differential oil from leaking while keeping water, dirt, and other contaminants out of the differential housing.

Over time, the original pinion seal can harden, wear, or become damaged through age, heat, and normal driveline movement. A leaking pinion seal can result in low differential oil levels, leading to premature wear of the crown wheel, pinion gears, and bearings. Replacing it with a Genuine Nissan seal restores the factory seal and helps maintain the reliability and longevity of your differential.
