06 s55 AMG vibration at 2900
Hello, how is everyone? I'm new on to this forum and need help! Getting a strange vibration at 2900 rpm out of my 06 s55 AMG, 123k miles. trans mount has already been replaced. has already been looked at by the benz dealer here in Grand Rapids, MI, but the couldn't figure out what was causing the issue. Has anyone else experienced this and gotten to the bottom of it? PLEASE HELP! Its my first Mercedes and I wouldn't trade this thing for the world (maybe a new s63 though). Any assistance is appreciated.
Thanks,
Cam

I am thinking the Harmonic Balancer. The rubber seal in the Harmonic Balancer will decay with high miles and move outward towards the timing cover, sometimes at a certain RPM. When the rubber seal disintegrates more or completely the HB will damage the surrounding parts and the timing cover.
Has your Dealer Service looked at this part when you had the car there?

Thank you for your input. And no, they did not mention anything about a harmonic balancer. I work at a used dealer and purchased the vehicle from the owner after he purchased his s65. they did transmission mounts and a new abc pump before I purchased the car and the problem persisted. when it was at the benz dealer (again before I purchased) they couldn't figure out why it was acting up. I'm going to mention something about the harmonic balancer and see if that gives them any ideas. Much appreciated my friend

Check ABC dampener
hi - I have an '01 S55, had same type problem, and it was the ABC dampener. Actually, mine was a whine and vibration around those rpm's, particularly on deceleration. My whine came from front left side of engine bay, which is where the ABC pump is located. The dampener is elsewhere under car though.
Replaced the engine and trans mounts ( very expensive) which didn't do a thing.
ABC dampener wasn't too expensive - you can do it yourself if you're inclined. I wish I had done that myself first.
Good luck !

ABC pump is a separate / different piece from the ABC vibration dampener. Dampener is under the car on the other side. When my dampener was bad, the vibration / whining sound (around the 2500-3000 rpm zone) came from the ABC pump area.

It could be harmonic balancer but I doubt it -- a wobbly crank pulley (harmonic balancer) wobbles at all RPMs, and if it was wobbling enough to vibrate the car, any dealer could find it. You would see it looking under the hood. If the engine mounts haven't been changed, I'd look there first. Virtually everyone recommends changing those with the trans mounts, but the trans mounts are so much easier, lazy service people will do trans mounts and leave engine mounts untouched.
Good luck and please keep us posted.
Cheers,
maw

And by the way, engine mounts, drive shaft flex discs, trans mounts and ABC pulsation damper should be on ANY dealer's checklist for vibration in these cars (in addition to wheels, improper tire wear, etc.). You might question whether that's the right dealer for you if it turns out to be something simple they should have known. I know we have some GRap folks here, who may be able to advise on a better service location. Good luck.

Yeah I agree with you 100% actually, the dealer here isn't the greatest. I'm getting it in at the dealer where I work late this week, we have a couple benz certified techs, just takes a little bit to get it in. customers first ya know

2004 S55 AMG vibration between 2k & 3k RPM
Hi guys!
Just wanted to share my experience as this issue of vibration drove me nuts.
I understand this is an old thread, but when you’re searching all information is valuable.
So a couple years back I bought a really nice 2004 S55 AMG with 125k miles.
From day one I felt some vibration under my seat coming from the general transmission area.
The vibration was especially noticeable between 2000-3000 RPM (moving or parked).
So I decided if I’m going underneath and I plan on keeping the car for a while I might as well replace all possible related parts.
On my list I did motor mounts, transmission mount, both flex discs and the carrier bearing.
I thought for sure I had most if not all bases covered.
*All parts were bought from FCP Euro.
I took the car for a spin and to my disappointment the vibration was still present. Maybe a bit less than it was.
So I thought the last thing left was the harmonic balancer (crank shaft pulley).
After replacing the pulley (about a year later), once again I was disappointed because it didn’t solve the vibration problem.
After doing more research, I decided to buy the transmission mount from the dealer.
After removing the transmission mount bolts I jacked up the transmission off the cross support brace just to do a test by taking the load off the mount.
Sure enough, the vibration was gone. So I decided to replace a less than one year old transmission mount (that had vibration from day one) and what do you know, the car runs smooth!

Yes! Sorry to inform you but these cars REQUIRE original equipment mounts. Everything else fails within a year or 2. So if your engine mounts were non-OE, you may as well replace them now.

P.S. my 25+ year old 500E has taught me to only use OE parts on these cars. Pay the extra money and save yourself some headache.

Didn’t think rubber pads were that hard to replicate.
Apparently those other “German manufactured”aftermarket parts are not up to snuff.
