2010 ML 350
My 1985 300D recently died so I just bought a 2001 320ML with 86000 miles on it, from a private party. At mid range speed, it feels like the entire car is swaying, or rocking back and forth ... as if you are on a subway, or someone is turning the steering wheel back and forth at about one cycle per second. Almost makes you sea sick. Does not seem to occur at low or high speed. It does not seem to have the frequence or shimmy of a wheel that is out of balance. HELP. I don't know what this might be related to, or where to start looking. Struts? Power steering ? What is 'body roll' ? ANY suggestions would be appreciated.
