I asked for a 60000 mile service on my 1973 280SE 4.5 MB. The MB dealer refused because they no longer have service techs familiar with old cars. I went back to them a week later stating that there was a clunking sound when I turn the steering from straight to either right or left. One time sound during the turn but louder in the right direction.The service manager said it could be the tie rods or ball joints and the I should bring it in. I did the next day but the service manager was on the road but I demonstrated the noice to another service tech. He drove it to the service area and five minutes later the car was back and the service man said the noise disappeared. Can putting the car on a lift clear the problem or did they something else so that they would not be required to service the 1973 car. I did not go with the car to the lift so I do not know what they did and they offered no info why the noise disappeared. My question is what did they do and is the steering clunk a dangerous condition even tho it is not present now.
