The Mercedes-Benz half-shaft oil seal was replaced. This 14-year-old car was about 10W kilometers. During inspection, it was found that oil was leaking from the half-shaft.
The location is at the rear right half shaft, with obvious oil stains. The dirt stains will cause the color of sludge to turn black and adhere to the surroundings, forming obvious dominant characteristics of the oil spill area. The leak can be seen at a glance.
There is a problem at the half shaft oil seal. Remove the half shaft and replace the oil seal! The cure rate is more than 95%, and the remaining 5% is caused by long-term oil leakage of the half shaft, causing internal dry wear and serious scratches. At this time, replacing the oil seal alone has no way to perfectly solve the problem. It can only alleviate the oil leakage speed. At this time, you need to replace the entire half shaft!!! It can be solved 100% without future trouble!
As for the duration and amount of leakage, it depends on the thickness of the sludge.

The half-shaft oil seal of this car does not leak for too long. You can also replace the oil seal individually for rescue. Minor oil leaks have no impact on the car for the time being. Some of them do not even need to replace the oil seal, and they will be fine for a few years. However, if the oil leaks are serious, the internal oil will be quickly consumed, causing dry grinding of the half-shaft. There is also too much harm. I won’t say much here, alarmist!!! We hardly encounter them.
Continue to remove the half shaft. This set of disassembly takes a lot of time. Place an oil drum on the ground where the half shaft is opposite. Oil will flow out and drip when removing the half shaft.
The removed half shaft oil seal is this rubber seal. The upper part has been stained with a lot of dust and sludge. Replace it.
By the way, the oil receiving drum placed on the ground did not receive a drop of oil. It was judged that the oil inside was seriously missing, and there was really no leakage at the half shaft.

Install.
Tighten the torque for each bolt using a torque wrench.
Add new liquid. The smell of this oil is really bad. I smelled it and regretted it. You can try it next time.
The last step is to remove the oil. You have to ask why not remove the oil first before installation, but clean it after installation?
Because it is easy to remove the oil from it if you clean it before replacing it, your correct way to deal with it is to clean the oil from it after the replacement is completed. This is the case for oil from many places, so remember.
