Hi Everyone,

Im new here so i’m not sure if anyone can help me? I have a 2004 mercedes c230 kompressor and when i’m driving on the freeway at anything above 60 MPH my car swivels side to side. I have changed a lot of suspension parts but still can’t find what’s causing this to happen to my car. It kinda feels like if you are moving the steering wheel left to right and the entire car just moves side to side. I can show you guys a video if that will help i just really need someone to help me that maybe has had this issue before and found a way to fix it ? My car has a little over 170,000 miles it’s a 2004. Please if anyone has any advice i will highly appreciate it.
I have replaced the following parts:
-Front Shocks
-Steering wheel bushings
-Inner tie rods
-Outer tie rods
-All 4 tires

Are you able to rock the car side to side by pushing on it when the car is parked?

Inspect the front ball control arms on the front car. Might be a loose ball joint or some damaged bushings where the control arms attach to the front subframe.

Hi Slammer,

I have replace all parts of the front suspension and I'm still having the issue to this date. I notice that its really bad once I hit 70+ miles per hour. Its so bad that the cars dashboard starts flashing for the traction control. I also tried rocking the car back and forth when its parked without any luck. Should I just replace all the rear suspension parts and see if it makes a difference? Any help is really appreciated.

I agree with Slammer.. inspect all (front and rear) control arms for loose ball joints, and/or cracked/ perished bushings..
when you have the wheels off the ground, and grab the top and bottom of the tyre, and wobble it back and forth, is there much movement in the wheel?.. it should feel nice and tight..

Hi Everyone,

I lifted the rear end of my car and i notice my left rear tire shacking. After removing the wheel i noticed that the upper 2 control arms are moving a lot by where the wheel is held. I have tried removing the bolts to replace both control arms but the bolts are stock. I have tried hammering them out without any luck. Does anyone have a how to video? or instructions to help me? I also order the tension bar since it was broken. Please any help I can get I would really appreciate it.


This bolt is stuck and can’t be removed

This control arm is the one that’s loose

Use an impact gun + impact socket as well as some penetrating oil (Liquid Wrench, PB Blaster etc.). Simply whacking it with a hammer is only going to damage the nut.

Does anyone know how to remove the upper control arms on a mercedes c230 2004? I have tried doing it but have no room to remove the bolts on the top control arms since the entire frame of the car is on the way. Does anyone how a how to video or any kind of help? I appreciate it in advance.

Hi Slammer111,

I was able to remove the bolt with a torch and hammer. Thank you!

Hi All,

Just wanted to let you all know I was able to fix my issue with my car. I ended up changing all the rear suspension parts, (bushings, control arms, subframe bushings, etc.) Thank you all for your help and suggestions. My car currently has around 210,000 miles!!!
