Restore smooth and reliable transfer case operation with this Genuine Nissan Transfer Gear Mainshaft Bearing, designed for Nissan Patrol GQ Y60 and GU Y61 models. This OEM bearing is located inside the transfer case on the mainshaft and plays a critical role in supporting gear rotation, maintaining alignment, and reducing internal friction under load.

Over time, transfer case bearings can wear, develop play, or become noisy due to age, lack of lubrication, or heavy off-road use. A failing bearing can cause driveline vibration, whining noises, poor 4WD engagement, or even internal transfer case damage if not replaced promptly.

Manufactured to genuine Nissan specifications, this direct-fit bearing ensures precise tolerances, smooth operation, and long service life in demanding Australian driving conditions.
