Hi kajtek, we will try to swap the wheels just to make sure but I think it is something else.. there is also that humming/whining noise, even at low speeds (±15mph).

I just replaced tires on our wagon.
The previous, low profile tires were giving me pretty strong whining noise at low speeds, that kind of quieted at higher speeds.
Lately I put original wheels back and still had whining noise, but that could be aged tires.
So now, on new Z-rated tires the car is quiet like Symphony waiting for music to start.

I have always had a vibration from 70 mph on to unsafe mph. With such finicky everything is connected cars, I agree with Kajtek1, start with tires and work your way in. After 2 sets of brand new wheels (18" & 19") and tires (diff brands) over time, my indie noticed my tires were chopped and I had play in my front bearings. Those were tightened up and the shimmy lessened. Of course it was not a G-AMG machine travel tightening of the bearings, but it helped. Since I placed miles on the tires with loose bearings, the tires wore in a uneven pattern so the tires are shot but not garbage yet. I am going to replace the front bearings and tighten them according to WIS machinist travel specs before I buy new tires- then pray. After that only the shocks/springs are left as I have replaced everything else.

Hi guys,
You are right, I will listen to your advice and have the wheels and tires checked this time once again.
I spoke to the workshop where I sent my E55 for dyno and agreed on a test run to see if the wheels and tires are perfect (even though we are speaking about new original AMG wheels and new Michelin tires).
The trick is to try the car at various speeds and see if you notice any vibrations visually - to my understanding, this will be the most precise method, complementing greatly Road Force Hunter.

An "aside:" where in the Dallas, Texas, area could I get a THOROUGH and COMPETENT check of wheels and tires for vibration (starts ca. 36 mph, worst ca. 42 mph, gone by c. 52 mph)?

1) This is not coming from your tires.
2) You will get ripped off for daring.
3) DFW has definitely no clue - try Mercedes.
4) You are going to waste an immense amount of time on a car that is just old. Autonomous driving is the fashion
5) A $10K repair bill won't shock any w210 owner today, will it?
6) Stop driving now! It is unsafe!

I don't let local shops work on my 210. You must supervise them if you do. They like to produce the greedy Texan style with the greasy finger prints all over your interior. DFW's services always lacked culture, pride and knowledge and can't be compared to e.g. German standards.

Mildly annoying, yes, but "dangerous?" Why is this dangerous? Obviously, I'd like to know why you think it is. Thank you.

Congrats! You appear to be a great physics expert, Sir! And that is what I expect!
I am leaving this forum, James.

Beverly Sharp

No-one will miss you, though it's too bad we won't have the benefit of your self-indicated brilliance.

Diffs are littering the countryside.. LOL That's the most brilliant observation I have seen in a long time.

Beverly Sharp, find a workshop with Hunter balancer.

I solved my vibration today....a road-force balancing at the indie-shop done by a w210 enthusiast. Made a huge difference. He said one wheel was off 2 ounces.....I may have lost some stick on lead at some point.

Beverly Sharp

I don't know what "road-force balancing" is. Please help me out with a description. And does it have anything directly to do with a Hunter balancing machine? Thank you.
James
P.S. I've had my tires balanced at three different indie shops, without a solution. It doesn't seem to be because of the tires, unless one is out of round. Confusing!

Bowyer

It is a machine that balances tires while applying pressure (like the car driving down the road) to the tires. At least that is my understanding.

A few weeks ago I bought tires at a 'tire shop' and the don't 'road force' balance. I've been chasing a vibration for a while. I took it to a local MB indie thinking I needed wheel bearings or flex discs or thought I had a bent rim. The mechanic balanced the set and it made a BIG difference. I really think it helps, and to have a technician who really cares and wants the job done right made a difference. He said the last shop who balanced my tires may not have cleaned my wheels thoroughly and I may have lost some of the the stick-on lead weights.

Try calling any tire shop to see if they offer the 'road balancing' equipment. It may actually be a Hunter product. $50 is what it cost. Hope this helps!

Here LIES the fourm King. WE are not worthy...
Lol. On the real I can see why u covet your outcome as the price for such knowleage an wisdom would b skyhigh.BTW thanks for the easy button

The interesting things with my car are:-
Low miles 25k
Vibration started when I ADDED the Quaife ....
I don't think I replaced the diff correctly and will start there... and get it aligned properly.
The Vibration seems to be worse some days than others
Nothing coming from the steering all coming from the chassis / rear so prop backwards
Seems at times to be worse when in cornering hard - then when I try again its fine !? Centre prop bearing is fine as is bushing
Feels like it could also be shocks / air susp.... as it feels almost like a travel vibration...
Vib present from 75mph and worst at ~90mph.... but car does not feel smooth like it has with the old diff.
On /off throttle makes zero difference....

Sry for hijack but this is driving me bananas.

Jan AMG

Hi Steve,

I feel you pain .. I have been dealing with the vibration the whole time I had my car (20,000Km) and replaced everything I could.

It's 100 percent not the Quaife ... I wouldn't doubt their manufacturing / mechanical perfection ... it must be something else.

Any news since your post?

You probably have sold your cars by now... but the vibration issue in the 40-60mphs when cold was solved. Check
https://forums.mbclub.co.uk/threads/....159248/page-2
I followed the instructions and after years of frustration and many $$$ spent I had peace...
... until my mechanic fixed the front end because of a broken spring.

Now I have a rattle/vibration sounds like motor/tranny mounts (it's not that, they are new) or cats (it's not that). In D or R with foot on the brake.
Similar response on similar vehicle after similar repair, so mounts and cats 100% ruled out.
Help would be great, and don't tell me to consider a new Mercedes, like the dealer did, it is basically new, made up of replacement parts, so it stays with me till one of us dies.

Hey Timsbc, check for loose or broken heat shields. Sometimes they will give the sounds you are complaining about and usually are a cheap repair.

So did the guy ever find out the cause of the vibration?

Jan AMG

Sorry for the confusion. I didn't. I thought I did but didn't, it was still there. Ended up selling the car. I'm offering $2,500 USD for the education / explanation / revelation to anyone who can enlighten me what was wrong there - it's a mystery to me until today.
My friend's W129 and other cars from that era have the same problem.

quik55

what was your exact vibration is?

guess I'm bringing up this old thread nut long story short I get a nice rumble/shudder/vibration from 18-22 mph from a slow start. Everything mentioned has been done gonna try shutter fix tomorow but don't think it's TC.

did full drive shaft fix anything?

Jan AMG

Hi, no it didn't.

crixus84

I have a 1998 mb e430 sport, my vibration is an oscillating vibration starts at about 60 and continues threw so much at it all ready now ball joints front cv axle.
I read over your post dis you say u replaced front cv joint assemblies? Im jus wondering
