As part of further preventative maintenance, I replaced both the engine mounts with fresh new Meyle engine mounts. Unfortunately no HD version available. Next time I will probably replace them with Mercedes Black Series mounts, as these are a popular upgrade.
It’s highly recommended to replace them, as it makes a major difference!
Replaced all 4 exhaust rubbers with OE AMG exhaust rubbers. Each AMG logo adds approximately 1 HP, which is good value for money 😛
I bought a special tool to make this easier, and I can highly recommend it! Made replacing them way easier and faster without the need for cutting them up or using flathead screwdrivers etc.

Engine mounts are usually forgotten as a maintenance item, but not for me! I checked my options and found that Meyle had an upgraded mount in their product line. The upgraded series from Meyle are known as the “HD” series and they are OEM+ replacements.
I chose the Meyle HD gearbox mount to replace the factory Mercedes mount. Fitment 100% and the build quality looks to be very good. The front engine mounts will be replaced as well by Meyle mounts!
Bought a special tool, which is particularly handy when replacing the engine mounts on a CLS55 W219 or E55 W211. The exhaust manifold takes a fair bit of space on each side of the engine and there is where this tool comes in handy with removing the bolt which sits directly under the exhaust manifold (on each side).

When you have an older car, always think about replacing the engine mounts. They are almost always made of rubber, which becomes brittle over time due to aging/drying out.
I replaced all the engine mounts, which tightens up handling and improves performance and reduces strain on components like the exhaust, as the engine swivels way less. Highly recommended!
My original gearbox mount was shot and I decided to replace the mount with a brand new reinforced polyurethane mount, which tightens up the shifting and allows for less engine movement, which is better for the exhaust.
One disadvantage, the cabin has added drone due to extra vibration. But the advantages outweigh the one disadvantage, so for me it’s a keeper!

Old vs New. The mount should not be able to move like that 🙂
And this is how it looks under the engine. Easy job, 2x 14mm & 2x 18mm nuts.
My front gearbox mount was shot. Found a polybush replacement part which is a easy swap. Remove 4x 18mm bolts, swap the part and tighten the 4x 18mm bolts. Noticed a big improvement in pickup and shift handling. The engine/gearbox is able to move much less, which helps in driveability.
I noticed that when lifting off (like shifting), there was a lot of movement / play in the engine / gearbox. So when I inspected the upper engine mount, I found the root cause rather quickly. The rubber deteriorated and there wasn’t much left of the original rubber bushing.
Having read the other options, like fitting a polybush, I went with the SuperPro version which looked like a good bit of kit. Mounting the new polyurethane kit was quite a breeze. Fortunately, the original bushing has a plastic ring 🙂 The SuperPro kit consists of 2 pieces, which makes the mount very easy to replace.
Result: a much better shifting car, putting the power down goes a lot better now. I will also replace the bottom gearbox mount with a polyurethane version soon.
Very easy job to do at home. This also applies to the S60 and V70, as these are quite identical.
Broken upper engine mount…
Tearing it down
Comparing old to new
Et voila!
