Hmm,

It is a simple seal and if the housing is damaged to where the seal is leaking ask him to show you where and why the part needs to be replaced.

Please let us know what happens.

Best, Ken

Unless the bushing inside the end of the housing is bad or the wrong seal was used that side should be simple. Or this is a right hand drive (what country of production) Then the passenger side would be the left side with that long internal shaft and the outer bearing. Still shouldn't be an issue unless the leak is actually a bad case seal.
