69k now.. And the 2nd diff left the chat. Same failure as the first one. The seal is just a symptom, the bearings disintegrated which took out the seal. I doubt I'll have this car long enough to get to 70k. Might talk the dealer into buying it before they get the parts(which are on national backorder with no ETA) take the hit on trade in, and get anything else other than this piece of sh!t But I'm on the hook for a $3600 repair of a problem that obviously isn't a "fluke" The first diff made it to 33k, and the second lasted 36k.
