I talked to the service manager and the tech today. They said they didn't see any oil leaking, so it appears there must be an intermittent problem. Hopefully they will find it so I don't have to worry about it happening while I am on the road. I might need to carry a few quarts of oil with me for a while, just in case.
A replacement boot for the half shaft is no longer available from GM, so they are ordering a new axle from Nashville. Hope to get this wrapped up next week, but I'm not holding my breath. The closer we get to Christmas, the more dicey it will be getting anything delivered quickly.
I was told that the body shop manager will be looking at the paint problem on my hood. I'm hoping it wasn't an impact that caused the paint to actually crack, instead of being scratches. So we will see.
Got a spare bay in the garage again.
