In most cases, the old pinion seal is removed by disassembling the differential unit, and the new seal is installed in its place using a suitable sealant.

This Nissan pinion seal is a precision-engineered component that is essential for maintaining the optimal performance and longevity of your vehicle's differential system. By preventing oil leakage, this seal helps ensure that your Nissan vehicle operates smoothly, safely, and efficiently on the road.

In summary, the Nissan 38189-U3001 Pinion Seal is a vital component in the power transmission system of certain Nissan vehicles.
