Nissan 4321001J10 — Rear Axle Inner Bearing
Overview
Inner rear axle bearing Nissan 4321001J10 supports the rear drive shaft assembly and accommodates radial and axial loads during vehicle operation. Manufactured from hardened high-carbon alloy steel, this tapered roller bearing features precision-ground raceways to withstand extreme mechanical stress in demanding off-road conditions. Exact specification measurements are 45 mm inner diameter, 85 mm outer diameter, and 23 mm width. OEM part number reference is 4321001J10, with alternate cross-reference code 43210-01J10. The unit maintains precise drive shaft alignment, preventing premature oil seal wear and retaining gear fluid inside the rear axle housing assembly.
This part fits Nissan Patrol Y60 and Y61 models produced between 1987 and 2010, fitted with 2.8, 3.0, 4.2, and 4.8-litre engines. Replacement becomes necessary when deep humming, grinding noises, or drivetrain vibrations emanate from the rear axle housing and escalate with vehicle speed. Further failure symptoms include excessive side-to-side wheel play, oil leakage past the inner shaft seal, or localized heat buildup near the hub assembly. Moisture ingress, lubricant breakdown, and surface spalling degrade the inner rollers and outer race over time. Installing a new bearing prevents shaft seizure, spline stripping, and catastrophic differential failure.
