This is a Genuine Nissan rear differential pinion seal to suit the Nissan Navara D40. It is fitted to the front of the rear differential housing where the drive shaft flange connects. The primary function of this seal is to retain the differential gear oil and prevent contaminants like dirt and water from entering the housing. Over time and with exposure to heat, these seals can become hard, brittle, or damaged, which compromises their sealing ability and can result in a differential oil leak, often identified by oil stains on the diff housing or driveway.
Replacing a leaking pinion seal is critical to prevent the loss of gear oil, which is essential for lubricating and protecting your differential internals. Using a Genuine Nissan part ensures you are fitting a component made to Nissan's exact specifications, guaranteeing correct fitment, performance, and reliability.
Installation of this seal is considered a moderate workshop job. It requires specialised tools to correctly remove the drive shaft flange and to set the pinion bearing preload upon reassembly. Incorrect preload can lead to premature bearing failure. You will need fresh differential gear oil to refill the housing after replacing the seal. A new flange nut or crush sleeve may also be required.
Please check vehicle fitment to confirm compatibility with your vehicle. Please contact us with your VIN details if you require further assistance to confirm fitment.
