Both mounts done now. I installed the correct mount on the driver's side and knocked out the passenger side while I was at it. Both mounts were collapsed maybe a half an inch, so I'm glad I did it. I took some photos, but my camera isn't being recognized by my computer right now. Just doing the driver's side really smoothed out the idle in reverse - very nice now.

The passenger side was a lot easier for several reasons:

1. I only had to do it once.
2. I already had practice doing the driver's side twice.
3. The top bolt can be reached from above and the bottom one from below. That makes R&R a lot easier than the driver's side.

Here are the part number for future reference:

Old one on the left side - 202 240 28 17
Old one on the right side - 202 240 30 17
New one on the left side 203 240 06 17 (with rubber boot)
New one on the right side - 202 240 30 17

Thanks for all the tips guys - it made it much easier.

Note to Jim -you are right about that 16mm wrench being an odd one. Most of my sets don't even have a 16mm wrench.

I just ordered the parts this evening at the MB dealer...will be tackling this project very soon...am looking forward to getting rid of a nasty groan which has developed whilst coasting, especially in a turn when the engine leans.

What purpose does that grey rubber boot serve then? On my car, it would be near the turbo, exhaust manifold, and steering column. The engine mount already sits underneath a heatshield, so whats the boot for?

Not sure what the reason really is, but I speculate the poor performance of the fuel line seals has contributed to exposing the mount rubber to Diesel fuel, which may hasten the mount's degradation. By the way, I often forget the "driver's side" can be a poor description of the side of the car as some markets have the steering wheel on the right instead of the left. So, on your car it would appear the rubber booted replacement mount goes on the side of the engine with the injection pump and the fuel lines. Which is likely the left side of the engine, facing forward in the car. Jim

Well its too late now

Its not here, its at my mates. If I put it on I'll have to cut it, wrap it over the shock, and secure it with a cable tie or two.

Personally I can't see how diesel would get onto it anyway, its just too far away to be bothered by diesel IMO.

For future reference, I have found some stock images of the two shocks.

I'm gonna be tacking the engine mounts on my NA OM606 soon,. I'll report back if there is anything out of the ordinary...

I did mine today...I tossed out the little rubber boot as I didn't see the need for it on the W210. It made it hard to locate the pin and would have also required lifting the engine higher to clear it. IIRC the boot is made for some cars where the mount is directly under the fuel system and leaks can deteriorate the rubber quickly. On the W210 the mounts are pretty far away from the fuel lines and as badly as mine was leaking the old mount was dry when I removed it so I elected not to use it on the new mount.

It does make a difference though having those new mounts...the car idles "like new" and is much quieter during acceleration. It also got rid of a groan that sounded like a bad wheel bearing when I would turn and take my foot off the accelerator pedal...glad I spent the $$$ to do this job sooner rather than later.

It does make an impressive difference doesn't it!

I will do mine sooner rather than later next time.

Maybe a little bit of redundancy here, but here are a few photos I took while doing the job.

It's now been a couple of days on the new mounts and I am still very happy I did this replacement everytime I drive the car. It's so smooth and almost slient now at idle...bad thing is now I can hear the tire noise from my snows that was always drowned out by the vibration/noise from the engine!

The car literally feels like new again

I can honestly say that my W210 has never driven any better than it does today in the 2 years since I have owned it...all of the work in getting it to this point is worth it since there isn't another car I could buy that I would enjoy driving more.

Same here Marty. Just took mine on a 500 mile drive today and it is really a sweet driver especially now with the new mounts. Had to muddle through a bunch of niggling little problems the first couple of years I've had mine too, but since I do all the work myself, labor costs didn't kill me like they might have had I taken it in to a dealer. And it's not even the labor costs so much that bothers me about a dealer. It's just the inconvenience of not having the car and wasting at least two days while waiting on the repairs. My dealer has been good to me and their work is typically well done.

Finally did the mounts last night! It was much easier than I thought. The upper bolt on both side was a 17mm and the bottom a 13mm - I was able to reach the driver-side mount form underneath rather easily. It was slightly tight due to the size of the ratchet but nonetheless, got her done. I didn't install that rubber cover over the driver-side mount as it was too much of a pain, couldn't feel her fit in right. The old mount didn't have it either so I didn't feel as bad :-)


Haven't fired her up yet, wanted the thread lock to cure prior to wrapping things up tonight. Plus I was exhausted last night. Started like 10-10:30pm and finished before 12am, taking my time.

Did the job on mine last week and engine seems to run much smoother. Add an inspection mirror to the list of recommended tools. It is difficult to feel for the alignment tab from below and you can slowly lower the engine right into the slot (see attached pics).

Also, left side mount is definitely easier to get from below. A 16mm or 5/8" box-end wrench does the trick nicely. Remember to release the fan shroud and exhaust spring-clip before jacking up the engine.
