Some months ago I decided to replace the engine mounts of my 240,000 mile MANUAL gearbox 1994 S124 E300 Diesel because they hadn't been done for years. I used genuine Mercedes mounts bought online from Inchcape Mercedes Oxford. For the first 25-30 miles when started from cold I get driveline vibrations when backing off the accelerator in high gear from about 40mph and below, for example when slowing down for a junction. Once the car is thoroughly warmed through the vibrations pretty much disappear.
My indy suggested replacing the front rear subframe mounts, so I did. Whilst this eliminated the slight driveline shunt I had been experiencing for years and made the gearchange nicer it had no effect on the driveline vibrations. He's now advocating changing the rear diff. mounts, which doubtless are ripe for replacement, but this involves five hours' labour so I'm in two minds.
Given that the vibrations are not present when the car's warmed through, can anybody suggest where the cause might lie? The propshaft doughnuts are in good nick generally BTW.
