hello; Did you hand carry in the DS or can they do it on site?
thanks
What I have is a hum while driving at constant highway speeds. I have no idea what it is so I want to start with the DS but others have told me it's the trans.
I'll get the DS done for now and go from there.

does it go away when you let off the gas? If so it could be in the rear end
