PLEASE HELP 300 se vibrates starting at 25mph all the way up

Good morning

I have a 300 se, with 212k miles I owned this vehicle for the past 6 years.

The vehicle is well maintained and I enjoyed it much for the first 3 years.

In the past 3 years the car is seating in my garage because i don't have the heart to drive it and cause more dammage.

The problem with this car is a vibration that starts at about 25-28 miles per hour, it is a severe vibration that you can feel in the driver seat it comes from the back of the car.

My old mechanic tried fixing it and I feel as if I was taken for a ride.

It all started after replacement of the flex disk. by same mechanic.

since then the drive shaft was replaced with a new one, the differential was replaced, transmission mount also replaced, one rear cv axle shaft assembly. The problem still there. I am desperate, I love this car and spent lots of money on it, I want to put it back on the road but the vibrations simply takes the car apart ( loosened up my dashboard)

Please, If anyone knows what can be the problem, Please help

PS- It is not wheel or tire problem, car shakes on the lift without wheels.

I suspect is is the drive shaft but i am not sure and don't have extra bucks to waste.

Thank you very much

I will post the solution once problem solved to help others.

Cant solve?

It started after the rear flex disk install?

Then look- thats the cause, and you need to get that flex disk properly reinstalled by a QUALIFIED mechanic. Keep the original part and take that old mechanic to small claims court!


Look, if it started after a "repair" then that is cause-and-effect, and that mechanic needs to be dragged into court. Dont buy anything else until you fix the flex disk in the back!
