just picked up a 2001 Mercedes Benz e320 rwd a month ago and i cant for the life of me figure out why the inside of the car keeps shaking, i sighned up on this forum in hopes of getting some information. This car had multiple missfires when i bought it so the first thing i did was i replaced the spark plugs and the coils and surely after that the check engine light went away and the codes went away as well. So thats the only thing I've done to my car since i bought it and it didnt really help, so going back to the original problem, when i turn the car on you instantly feel the vibration and shaking on the steering wheel, and i dont think its engine related at all, it also gets significantly worse when you turn the steering wheel left or right, again this is when the car is parked. it also gets worse when i put the car in reverse and in drive its the same thing as in park but when i give it gas and start to pick up speed the shaking completely disappears, especially on the highway i dont feel anything at all, its very comfortable, this only happens when my car is completely still. i read a couple of other forums and people were saying to replace the transmission and engine mounts but i dont think that the problem because i gave it gas when the hood was open and the engine didnt move one bit. i also read another forum where this guy had exactly the same symptoms as me and he fixed it by replacing front axle shaft, i think that might be the problem but before i tackle this on i want to know if anyone has had the same problem as me because i dont want to drop a bunch of money on parts not knowing what the problem is 100%. any help or advice would be greatly appreciated thanks.
