    It is easy. Just pull the driveshaft, pop the old one out(becareful not to pry against the housing or you can break it) and tap the new one in. One note, those seals always leak. That seems to be how it stays lubricated. I replaced mine before my SYE and it didn't take long to start leaking again.

    Yep. I replaced mine in my 208, and it was easy. But it started leaking again not to long after. I have heard if you put some RTV around the seal to case mating surface this helps some.
