Why Should You Avoid Replacing the Half Shaft Oil Seal When There's Oil Seepage?

[JesseFitz]

The installation techniques of repair shops and the quality of half shaft oil seals are problematic; replacing them might be worse than leaving them as is. Reasons: This is mainly because the installation techniques of some repair shops and the quality of half shaft oil seals are problematic. Many vehicles experience worse oil seepage from the gear oil in the transmission’s front and rear axles after replacing the seal. As a result, many believe that replacing the seal leads to more severe oil leakage, making it better not to replace it at all. Reasons to Repair a Leaking Half Shaft Oil Seal: The oil seal prevents oil seepage and leakage. Consequences of Not Repairing: If left untreated, it will accelerate the loss of gear oil in the transmission’s front and rear axles. Over time, this will increase wear on the gears and mechanical components, leading to damage. Whether it's a half shaft oil seal or any other oil seal, if there's leakage, it must be repaired. Otherwise, the oil will only continue to leak more and more.
