1987 Mercedes Benz 560sl • V8 2WD Automatic • 160,000 miles

When starting out from a dead stop there is a thumping noise coming from the drive train. I have to let off the gas pedal and kind of baby it along and than it stops. It happens from a stop until getting to 25 to 30mph if I give it to much gas. If I start out very very gradual with the gas pedal its not a big problem, but if I give it to much gas its really bad. Could it be something with the drive shaft? I'm not mechanical at all so I'm just trying to get an idea before I take it to get it checked out this spring.

Thank you
