What are the causes of drive axle oil leakage?

[AryaLee]

The reason is that the rubber sealing ring is subjected to alternating changes in temperature for a long time, causing the sealing ring to lose a large amount of plasticizers and softeners, resulting in corrosion, aging, and hardening. Initially, oil seeps out, and gradually, oil dripping occurs. Over time, the sealing ring may break. Below is more information about drive axle oil leakage: 1. There are several obvious locations for drive axle oil leakage. For the central reducer, oil leakage often occurs at the input shaft, usually due to damage or wear of the input shaft oil seal, or relaxation of the oil seal spring. 2. During maintenance, it should be noted that if oil leaks from the outer ring of the oil seal, it indicates a loose fit between the outer ring of the oil seal and the housing. 3. During reassembly, the outer ring of the oil seal and the oil seal seat hole of the housing should be thoroughly cleaned, and adhesive should be applied to the outer ring of the oil seal before installing it into the seat hole.
