Hello and greetings from Bulgaria. Recently i have a really nasty problem with my merc w211 4matic 2009. When i drive slow (maybe 15-20 km/h) it bounces (maybe from the back left)... when i go over 110 km/h it vibrates hard.
Things that ive replaced:
Things that ive replaced:
- new rims and tyres
- new brake discs and pads
- checked suspension many many times in many many shops
Please tell me what everybodys missing when diagnose my car... Thank you so much!
Could be an issue with power transfer from the 4matic transfer case. Also check the flex discs on the driveshaft.

Maybe you're looking too deeply. If you can feel it at low speed and it vibrates at high speed, maybe the wheel isnt central on the hub. Are the wheel centres too big for the hub and they (or possibly just the one you suspect) centering on the bolts instead of the hub in which case you need spigot rings, or possibly something is limiting the movement in the Universal joints in the drive shaft and the drive shaft is trying to lift the wheel as it turns. I'm not a car mechanic as such, I'm an engineer but the problem you have would be caused by either of the above. Sorry if I'm way out, like I say I'm familiar with drives, not with your car.
