Okay, I am having a strange issue with my 2000 Chrysler Sebring convertible.
Once you hit 60 there is a vibration coming from the center of the front end (almost the transmission or flywheel area) that almost sounds like rubbing of some kind. Its strong enough that you can feel the issue not only through the gas pedal, but in the floor boards of the passenger side as well.

It's an automatic so that rules out my only suspicion.
Thanx for you help!

 

sounds like you need to check the drive axle

 

I'm also facing same problem at my Chrysler Sebring convertible, Main issue is that vibration comes from middle point. I couldn't solve in that issue till. Now i become fade up as it's not comfortable for any user. Please advice me from any one end if you know.

Thanks in advance

 

IF the passenger side axle is a 2 piece design, there is a sealed bearing near the middle of the axle shaft, very near to where the pass.side inner CV joint is. That bearing does wear out and needs to be replaced.To check it, get underneath the car(on ramps preferably), and try to move the trans side of the shaft for any movement (looseness) at that bearing area.

 

Be careful not to speed (S 4dr Sedan (2.4L 4cyl 9A), on the highway, and have to use cruise control so I won't speed. Smooth car n very much user friendly.
