Yet another XC90 vibration topic

[Pekka]

I read the forum and cannot find any vibration issue that seem to mimic mine (XC90 2007, lots of milage)

Symptoms are intermittent - whole car start to vibrate when:
- slight constant acceleration, more often at slight uphill driving
- when I let go of accelerator vibrations stops
- OR when I press the accelerator harder and car accelerates more vibrations stops
- sometimes when coasting downhill the car also start to vibrate.

This does not happen all the time, it is intermittent. Mechanic says CV axis are fine. Flushed transmission with no change.

Ideas?

I had a similar issue when I first got my 08. you could feel the vibrations under slight acceleration or making turns. It was the front axles. There is a TSB for those as the grease dries in the CV.
