Stelvio NTX, 2013 [36,000 miles]
Just forward of the CARC-split with the swingarm is a small fitting meant to hold the brake line that is attached to the swingarm with threads into the bottom wall of the swingarm. Evidently, the hole runs all the way through the wall of the swingarm (perhaps that's a useful thing as it exposes any seal leaks). I've got oil dripping out of that hole.
It's either oil from the transmission (and a failure of that seal), or oil from the rear drive box (and a failure of that seal). The drips make a mess of things, but I've not lost enough oil to tell where it's coming from.
Question 1: Is this likely from a poor seal at the transmission or the drive box? Gravity would indicate it's coming from the transmission, but oil leaks can be sneaky things.
Question 2: If I pull the CARC off the swingarm, is it an easy thing to check and replace the driveshaft seal? The service manual indicates that it won't be trivial. Evidently there's a rubber bellows unit as well as a seal (which might require a special tool to get to)?
Sigh... The Stelvio is still under warrantee, but my local dealer is gone. If this is something I can take care of, I will; otherwise, I'll put aside a day or two to take a long ride to an authorized dealership. The leak isn't something that would prevent the ride.
