Iv had this issue with my 07 cobalt lt sense I bout it in 09. The front end shakes when I acceleration fast right in to the steering wheel. It also shakes at random intervals just going down the highway and also when I break. Iv takin it to several dealers and they can't find anything wrong. It's not the wheels or the rotares because iv balanced the wheels and turned the rotares. Break pades have been replaced and so have ball joints and it still shakes.

 

Check your axles and control arm bushings

 

Does it pull at all to either side? when braking?

 

Worn Trailing Control Arm Bushings and/or worn strut mounts.

 

No it doesn't pull either way when I break just gets worse in the steering wheel

 

I had steering wheel shake. Replaced the entire control arm. So basically new ball joints, front and back bushings and new arm.

Shake went away.

I'm guessing rear control arm bushing is bad.

 

Control arm bushings and/or CV joints on the axles, is the car lowered?

 

My car used to pulsate like it had warped rotors when braking from highway speeds. New CABs fixed this.

 

I'm having similar issues. Sad news I've had cabs sitting on my dresser for weeks just can't get it into the shop. I'm busy or they are full of cars mabe Monday haha cabs will probably fix your issues get ottp or powell.

 

when you say cabs do you mean control arm bushings.

 

Yes thats what he means
