Cracked Driveshaft Flex Discs May Cause Driveshaft Movement/Vibration on Mercedes-Benz S550

A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.

Tires and floor of vehicle vibrates while driving. Rides rough especially at high speed and can be felt more on the passenger side of vehicle. No malfunction appearing on dashboard. Checked forum and called mechanic to check out.

Just purchased from Mercedes of Sarasota (FLORIDA) and noticed the vibration in the seats and floor when I let of the accelerator at 70 mph within 18 hours of purchase. Dealer first though it might be imperfections or bent rims. However when they tested the car with new rims it continued to vibrate. They just called me to tell me they were replacing the drive shaft but I am not sure about the flex joint discs. I will update.

I have balanced the tires twice, the rotors have been replaced and tires replaced. Problem still exists.
Front flex joint cracked and caused transmission failure due to vibration
I have the same problem with vibration within six month the transmission started sticking and that been going on for four month. Dealer worked on the transmission and within two to three week problem was back. The dealer said they can't find a code so they can't fix the problem. I complained about the problem while it was under warrenty the car was in and out of the dealer and change a number of things but the problem still exist. exist.Pulling on the highway from the on ramp and the car would not go. Pull over to the side of the road restarted the car and it was went. Very scary situation almost go hit in the rear by a car. Dealer giving me the run around. Car not fixed.
