Just another problem, occured when taking my w 124 out for a spin with new engine mounts on, an unusal vibration whas felt before a bang and loud metalic sounding rattle from under the car. At first i thought the exuast pipe had fallen down but i found that part of the driveshaft had appeared to be disconnected, it's where there is a rubber ring at the loint. I managed quite easily to push it back in place and get to destination. Just wondering if any peeps with knowlage of these old 300d 's could advise me on this. It sounded very serious at first but when i pushed shaft back in place the noise was gone on last part of journey, which i crawled home just the same.
