A few months ago I started to notice that the car is not as smooth a ride as it once was. I shakes at Hwy speeds staring at about 56 MPH and does not realy smooth out until just below 80 MPH.
Given that my new job requires me to drive 800 miles per week on the Hwy, I cant stand this continued vibration. It seems to be more "under my seat" than in the steering column.
Here is what I have had done to the car in the last month;
All 4 rotors & pads replaced.
All 4 tires replaced with Cooper CS4 80K tires.
Aligned & Ballanced. (Twice)
Intermediate stearing shaft replaced.
Left front wheel bearing replaced.
I have gotten the car up to a speed of 90 MPH and slipped the shifter into nuetral and allowed the vehicle to slow down on its own and as it came down through 75 MPH, it started to shake and it smoothed out at about 57 MPH.
The shake is not violent but it is annoying.
I have two seperate mechanics who scratch their heads over this issue. They do not work at the same ASE shops.
Feedback would be great!
have the same problem?
