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.

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.
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.
I have balanced the tires twice, the rotors have been replaced and tires replaced. Problem still exists.
vibration on steering wheel and floor
My S550 has 70,000 miles. However, on the front driver side I can hear a metal-metal squeezing noise, almost like a whistle. I replaced the brakes thinking that the brakes were the source, but the noise did not stop. When we lifted the car, we realized the sound was coming from the drive train. I didn't repair it yet but I might have to go to the dealer.
I began feeling the same noted vibrations in the center of the car floorboard at about 1500 RPM and again at 1900RPM. It felt as if the transmission was not shifting at the correct time. The center of the car would vibrate and there was a noticeable rumble. The dealer said motor mounts - changed them and still had the problem. The center bearing support for the drive shaft was shot - replaced it and had some relief. Now the vibration is back We'll try the flex disc next. One mechanic stated that maybe the dealer did not put in the newest upgraded motor mounts - how does MBZ engineer 3 motor mounts that do not last more than 85,000 miles? This was a $110,000 car new. Very disappointed in MBZ
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.
