W205 - C43/C450 Transmission-Engine Mounts Replacement
I ordered my engine mounts as well as my transmission mount for my car. While I'd love to do them myself I can't seem to find any sort of guides anywhere. Has anyone had experience swapping out engine mounts on a M276?
They seem to be difficult to switch out. The car has slight vibrations which I'm sure swapping the Transmission mount will take care of but since I got a good price on the engine mounts I ordered everything all at once. Car has 78,xxx miles.
I have a shop that can do it for me, and if they do I will post details on here so that others can see how to do it.

This seems very premature for engine or transmission mounts having to be replaced.
Either way, changing engine mounts on any car is the same, you need to lift the car, place a jack under the engine and lift it so that you can unbolt the engine mounts. You will not find any information online and changing, as I said, it's premature.

Mileage seems about right to me.
I would image the difficult part is the turbo/exhaust in the way of the bolts for the motor mounts. Not sure if they can be done easily with that still attached to the car.
My local shop quoted like 4 or 5 hours to do all of them which isnt bad. probably should have had them do them, but im probably going to be swapping them myself in another month and cursing that decision for 6hrs lol.

I swapped both Flex-disks on the Drive-shaft already which improved it slightly, so the transmission mount will most likely solve the issue.
But, since I have the engine mounts I'll just knock them all out at once.
I'll try and have the shop I work with document everything

The dealership found the driver's side engine mount leaking out the internal fluid. 6x,xxx miles on car. The quote was many hours, like 6 or 7? I had them replace both sides and the transmission mount. Very expensive.
