knock over heavy bumps

[sean sherry]

Scuttle shake ? too distinct . A cracking noise , like say a broken support strut under the dash. I had the instrument cluster out twice and can't see anything loose or broken. Including two of the nuts that secure the dash assambly. All tight. Noise is the same with the hard top on or off. Nothing loose under the bonnet including the heater motor under the panel. I know noises travel but I feel I could reach out and touch it. The front suspension has had a major rebuild including the shocks. This is now spoiling a well sorted car. Has been like that since I bought the car a year ago '81 280 SL 107

All contrabutions greatfully received........ Thanks Sean

If you have a fire extinguisher fitted to the drivers seat check if the bracket is tight.
