Vibration on highway
Hey guys trying to figure out what is causing some pretty bad vibration only on the highway.
This started after getting some tires taken off / new ones put on and replacing my rear guibo. both were done same day.
When i'm driving below 50, flooring it, braking or anything else the car feels completely normal, once I reach about 45-50+ miles an hour the car starts to vibrate fairly violently. It almost feels like it vibrates 3 times then stops then 3 times then stops over and over again.
At first I thought maybe something wasn't lined up or bolted correctly with the rear gubio but after double checking everything appeared to be normal also I feel like the problem would be felt at any speed if it was driveshaft related.
My second thought was that the wheels must not be balanced, went to my local tire shop that told me all the weights had fallen off one of my front wheels. Thought that was definitely the problem but the car feels absolutely no different.
Any thoughts? Thanks

I have the same issue. I havent resolved it since i dont drive the amg as much and its above highway speeds.
Its not a constant vibration its like a hearth beat kindof thing and between each vibration the tires probably spin many times at that speed. This is telling me its not the tires.
Whats a guibo?

I see, yeah my first thought was tire / wheel but still nothing, going to try putting two completely difference wheels on up front and see if it rides any different

I have a C280 which had a vibration between 55-70mph. a Wheel balance only solved for the problem a few days. Different AMG wheels resulting in the same vibration. I changed the wheels bearings, control arm bushings, and steering damper all to no avail. I simply lived wit the issue until one day a clear knocking noise developed in the front end. Upon inspection the rear control arm mount had cracked and was allowing some movement under load. Once I had this repaired, not only was the knocking noise gone but the vibration completely disappeared. Kind of a long shot but I would inspect the control arm mounting points.

If the exclamination marks below represented vibration in the road then this is how it would feel
Between the exclamination marks the car will cover a couple car lengths without vibrating. If it was a tire or wheel issue I think it would be constant.

Constant vibration below i fuess would be

Is that how yours behaved?
