What is a shaft seal used for?

A shaft seal prevents transmission oil from leaking past a rotating shaft where it exits the gearbox housing. They are common wear items and should be replaced whenever the driveshaft or gearbox is removed.

What material is this seal made from?

NBR (nitrile butadiene rubber) — the standard sealing material for most manual transmission applications. It offers good resistance to petroleum-based oils and operates effectively across typical gearbox temperature ranges.

How do I know when a shaft seal is leaking?

Oil residue or drips at the driveshaft entry into the gearbox are the primary sign. Low transmission oil level without an obvious source is another indicator.

Is this the correct seal for my vehicle?

Please contact us with your vehicle registration or VIN to confirm this seal fits your specific gearbox and driveshaft diameter.

Should I replace shaft seals in pairs?

Where the gearbox has two driveshaft exits (front-wheel drive), it is good practice to replace both seals simultaneously to avoid having to re-access the gearbox shortly after for the other side.
