Pinion Oil Seal for the rear differential, running on the drive pinion shaft.

The seal sits where the pinion shaft enters the differential housing, behind the drive flange. It retains the axle gear oil and excludes dirt and water from the final drive as the pinion rotates.

Frequently asked questions

What does the TZB500100 oil seal do?

The TZB500100 is the pinion oil seal for the rear differential. It sits where the pinion shaft enters the diff housing, behind the drive flange, retaining the axle gear oil and keeping dirt and water out of the final drive as the pinion turns.

Which Land Rover does this pinion oil seal fit?

This pinion oil seal fits the Land Rover Discovery 3 (2005-2009) rear differential. Confirm it's the rear diff pinion seal you need before ordering, as axle seals vary by position.

What are the signs the pinion oil seal is leaking?

A failing pinion oil seal typically shows as gear oil weeping at the front of the rear differential, around the drive flange and propshaft joint. Left unchecked the diff can lose oil. It's usually replaced whenever the drive flange is disturbed.

When should the pinion oil seal be replaced?

Replace the pinion oil seal whenever the rear drive flange is removed, or if it's leaking. The flange nut must be reset correctly on refitting to preserve pinion bearing preload, so torque it to the workshop manual specification rather than guessing.
