In this episode of Restore It, we restore and rebuild the differential from the Mercedes W123 2180CE. I noticed it was leaking at the front and rear when I had the car on the lift. I asked the owner if he'd like me to restore it and he of course gave me the go-ahead. This episode documents the entire process.
