The semi-axle of the car serves as a rotation-transmitting element from the motor to the drive wheels of the car, supports the ability to turn the wheels and allows the suspension to produce smooth movements with minimal vibration. Often the axle shaft is called the drive shaft.

The advantages of an oil seal usage

The TOPRAN brand Oil Seal, manual transmission is an elastic rubber element designed to seal the inside of the axle stocking and the axle shaft. The part seals the assembly, prevents oil leakage and provides protection from environmental factors. An oil seal is installed in the front axle of all-wheel drive vehicles with a continuous axle.

The material of the seals is a wear-resistant rubber with a flat outer side. The reverse side of the part has an outer edge adjacent to the body and an inner edge with a soft seal and a spring that provides a better fit to the shaft. Oil seal replacement is necessary when oil leaks from the front axle housing through the outer part of the stocking and enters the steering knuckle. Such problems can be caused by wear of the working edge, insufficient contact with the outer wall, tear or mechanical damage to the seal.
