Professionally Reconditioned with Premium Components

Every Nissan Patrol 4.1 rear differential centre is stripped down, thoroughly cleaned, and evaluated for gear tooth wear or shaft fatigue. We rebuild these units using premium Japanese bearings and seals, setting the ring-and-pinion backlash and tooth contact patterns to exact factory specifications. Genuine Nissan and quality aftermarket parts are used to ensure maximum strength and longevity under heavy towing and off-road driving.

Common Nissan Patrol Rear Diff Problems

High-kilometre and hard-working Patrols commonly develop worn or broken LSD clutch packs, pinion bearing whine, oil leaks, and slop in the drivetrain. Opting for a factory-spec reconditioned differential centre provides a far more reliable, long-term solution than chancing an untested second-hand unit.
