First place to check is the bearing at the rubber boot. Follow the column all the way to the floor from the inside driver's side and have a look. If you cannot tell, take a picture of the junction and post. There is a big rubber boot there.

I should have added - the fix is to push the bearing back down. Not much to it. If you do some searching you will find pictures of correct and incorrect. The set up is the same for just about any 2000 to 2010 Volvo (maybe more).
