Small Pinion Diff Bearing - Nissan Patrol Y60 GQ & Y61 GU

This small pinion bearing is located within the front or rear differential housing (diff centre) on Nissan Patrol models equipped with the H233 differential. It is one of two bearings that support the pinion gear, ensuring it spins smoothly and maintains correct alignment with the crown wheel gear.

Over time, differential bearings can wear out due to immense pressure, heat, and potential oil contamination. A worn pinion bearing is a common cause of a whining or humming noise from the differential, which often changes pitch with vehicle speed. Replacing this bearing is essential during a differential rebuild or when signs of wear become apparent to restore quiet and reliable operation.

Product Features

• Premium Japanese Quality: Sourced from leading manufacturers like Koyo, NSK, or Timken, these bearings are made from high-grade, heat-treated steel for exceptional strength and a long service life under tough Australian conditions. Using an inferior bearing risks rapid failure, which can cause catastrophic damage to your crown wheel and pinion gear set.
• Direct OE-Specification Fit: Engineered as a precise replacement for the original part, guaranteeing a perfect fit. This restores correct pinion gear alignment, protecting expensive internal diff components from premature wear.
• Eliminates Drivetrain Noise: Directly addresses the common whining or humming sound caused by a failing pinion bearing. A new bearing will restore quiet operation and a smoother driveline.
• Essential Rebuild Component: Replacing differential bearings is a complex workshop job that requires specialised tools to set bearing preloads and gear mesh correctly. During a full rebuild, you will also typically need the large pinion bearing, carrier bearings, and a full set of seals and gaskets.
