Rear seal replacement

Lol. Yes I've done the rear main (on a 318 ) while in the car. Was a major PITA for a simple seal. It was the old rope seal and wouldn't come out except in pieces. I had to loosen the main bearing caps so it was easier to remove the seal, then retorqued them down to factory spec.

This really is a no-brainer...replace NOW. Should be stupid-easy to do, and not an expensive seal either.
