I've driven sticks most of my long life. My brand new 08 stang, only have 400 miles so far. Pretty loud clunk whenever I let the clutch out, especially hear in in 2nd and 3rd gears. Sounds like play in the drive shaft. Doesn't sound like something I should hear on brand new car. As this is my first Mustang, any ideas what it might be? Is this common? (It did sit on a lot for a year looking for a buyer.) Tx.
