I found a yellow stain in the snow this morning where I had parked my Subaru which I haven't been able to identify whether its just run off or an actual leak of some kind. It was under the rear axle.
If its under the rear axle, it could be differential oil, but I think it was probably some waste from a dog or a cat trying to keep warm under the rear wheel of the vehicle.
Have you seen it again?
If so, take the vehicle to a good shop you know.
