Strange Vibration In Front End

Recommended Posts

I have a 2008 GT500 with Continental Extreme Contact tires in very good condition. Pulling in to the garage I ran over an object that punctured the front pass tire.

Took it in and had it fixed. Since then I have had a pretty strong vibration. Took it back and they rebalanced both front tires again and noticed a loose band that holds the sensor.

They said they fixed that. Got it up on the Interstate today and had it on cruise control at 65 and it was vibrating the steering wheel in a "cyclical" patter.

It would be almost completely calm then slowly get more and more vibration after a few seconds and then ramp back down to calm. Any ideas what might cause this type of

sinusoidal vibration?

At what speeds are you getting the vibration & is it consistent at the same speed? If the band is not tight it could have shifted.

Ever consider going with valve stem TSPM.

On a 2008 GT500 it has a band type sensor which has not only a strap to hold onto the rim but it also is held on with two sided tape (like which is on wheel weights) to prevent it from shifting it around on the rim. So it would be highly unlikely for a sensor to move even if the band became loose which is also unlikely unless some tire guy takes a shovelhead from the tire mounting machine and drove it into the side of it. Sounds like either someone doesn't know how to balance tires or doesn't have their equipment calibrated properly. There is the possibility that the tire has shifted position on the rim or it may have excessive load force variation. JMO

 

 

It could also be that the tire has belt separation which was caused from the puncture.
