Key Features

Complete assembly with metal housing, ready to fit
Oil-resistant rubber lip with garter spring
Stops the most common rear axle oil leak

Signs of Wear

The classic symptom is oil thrown on the inside of the drive wheels and around the axle housing, followed by a humming final drive when the oil level drops. Running the axle low on oil destroys the crown wheel and pinion – replace the seal as soon as a leak appears, and refill with the correct gear oil.
