Me too. Just signed up today because I bought a nicely maintained 2010 XC60 3.2 yesterday. I have owned Volvos since 1980. My first was a 1974 164e. That beast went to 335,000 miles and still...

I am thinking that it might be the CV joint/axles. Mine has 100,000 so I just may replace them as mine is doing the same thing as yours.
