The oil leakage of semi-axle oil seal is mostly caused by the aging of oil seal. Therefore, if the axle shaft oil seal is found to be aging or damaged, the entire axle shaft oil seal should be replaced. Secondly, when changing oil, it is necessary to clean the vent hole of the reducer, and the semi-axle oil seal should be made of excellent quality products to avoid buying inferior and counterfeit oil seals. The last point, which is most easily overlooked, is that the main oil seal should be installed correctly, otherwise the oil seal will not achieve its due sealing effect.

Precautions:
It should be noted that the surface roughness of the half shaft is too high, and the lip of the oil seal is easy to wear and leak oil.
Burrs, sharp corners and spiral machining marks at the chamfer are easy to scratch the lip of the oil seal, resulting in the initial seal failure of the oil seal.
Avoid or reduce defects such as shaft damage, sand holes, eccentric installation and radial runout.
If the chamfer angle of the aperture is greater than 45 degrees or there is no chamfer, it is easy to gnaw or scratch the oil seal, resulting in the outer diameter of the oil seal, assembly tilt and deformation of the oil seal framework, which is easy to cause oil leakage or oil leakage in the early stage of the oil seal installation machine.
