Well I got the Differential rebuilt in September 2016. In the spring I put some differential oil in the differential and then I mounted it and then a couple of days after it started to leaking at two places.. I was pretty pissed since they had my differential all summer. So last summer (July 2017) I brought it back to the garage where they rebuilt it and they had it for a week since the told me they wanted to make sure it doesn't leak anymore. So I picked up the differential and re mounted it into the car and a couple of days after again it leaked at the same location.. I called them again and they specifically told me this.. You have to turn the shafts for the seals to seat sometimes. They will stop leaking then. It’s etc silicone on the cover not a gasket. I cannot keep removing the differential and carrying it around. it's powercoated and already chipped. What would you guys do if you were in my shoes..
I'd be royally PO'd... But I agree with Derek. Cut your losses and find another shop. On a side note, I have no idea if that "turn the shafts" thing makes any sense but do you have any opportunity to try this.....
How many guys are turning the shafts over the winter? Imagine the dealers lot covered in oil back then where the Corvettes are parked on display. Haha great for sales...
Corvettes and leaks does not compute. Bet it owners manual makes no mention of this nonsense. My H1 has a similar driveline arrangement and it doesn’t leak either.
I would have completely flipped out if some shop tried pulling that BS.
