Maintain smooth and reliable gearbox operation with this Genuine Nissan Patrol GQ / GU Main Shaft Roller Bearing, designed for TB, TD, and ZD series gearboxes. This OEM bearing is engineered to support correct main shaft rotation and gear alignment, ensuring optimal transmission performance and long-term durability.
