This is a Genuine Nissan power steering rack top pinion seal.
 It is is essential to replace this Seal while performing a Rack Rebuild, as the originals are usually in very poor condition, due to the close proximity of the exhaust headers. The Top Pinion Seal is not sold separately by Nissan. Typically, this seal comes as part of the pinion housing, which Nissan has discontinued, making the seal unavailable through traditional channels.

However, we have identified a compatible Nissan part number that allows you to purchase this crucial seal independently. This ensures that Z32 owners can still maintain their vehicles even though the original pinion housings are no longer in production
