Do you have any buddies that would want to F*** with you? A popular joke amongst my coworkers is to crawl under someones car with a couple of plastic "Tiewraps / Zipties" and then zip a couple of them onto the driveshaft. If you do 5 or 10 of them it makes a helluva racket. One just makes a nice steady whack whack whack....
Just a possibility.
