Hello Click and Clack!!
I have a 2012 Mercedes Benz E350, sedan. It has 53700 miles.
From about 40 mph, I hear a roaring, grumbling noise from the engine. And I feel vibration. The vibration is felt worst on the floor of the front passenger. Additionally, I feel a grating sensation when slowing down- with the foot off the accelerator, and also when braking. The front 2 tires have feathering- I can’t remember whether it was on the inside or outside for the tires.
I replaced the existing tires with new tires-- the Continental Extreme Contact DWS 06. The mechanic told me he found a stripping of the front right wheel. He checked the shocks, and found them a little discolored, but otherwise in good shape. I got the bearings tightened in the front wheel, and got an alignment.
I don’t feel the grating sensation when slowing down Good! But the vibration and growling is still there- albeit not as much as before the new tires, but yes, still apparent!
The dealership told me it was a bad motor mount, but the independent shop did not see this to be the problem.
There must be something coming in contact with the wheel in the front right side, to have caused the roughness of the metal. What can this be? Is the problem also the cause of the roaring sounds, accompanied by the vibration? Do you have any idea what’s going on??
Thanks for reading my email! I love your show!
