This genuine Nissan differential pinion nut is engineered for the rear differential of the Nissan Navara D40. It is located on the end of the pinion shaft and is responsible for securing the drive flange to the pinion gear. This nut is a critical component for setting the correct pinion bearing preload, which is essential for the longevity and quiet operation of your differential.

Due to its design and the high torque required for installation, this nut is considered a single-use item. It can be damaged or stretched during removal and must be replaced whenever the pinion seal is changed or the differential is rebuilt. An inferior or reused nut risks backing off, which can cause catastrophic failure of the differential gears, resulting in a costly repair and a major safety issue.

Product Features

• Genuine Nissan Part: Manufactured to OEM specifications for guaranteed fitment, performance, and reliability on your Navara.
• High-Tensile Steel: Constructed from materials that meet Nissan's strict standards, ensuring it can achieve the correct torque and preload without stretching or failing.
• Stake-Lock Design: The nut is designed to be staked or peened into a groove on the pinion shaft, providing a mechanical lock to prevent it from loosening under heavy load and vibration.
• Correct Thread Specification: Ensures a precise and secure fit on the factory pinion gear threads, which is vital for driveline safety.

Installation Notes

Replacement of the pinion nut is a workshop-level job that requires a high degree of mechanical knowledge and specialised tools, including a flange holding tool and a high-range torque wrench. Incorrect installation, torque, or preload setting will lead to rapid and costly differential failure. This nut is almost always replaced with a new differential pinion seal. You will also require fresh differential oil to complete the job.
