This noise started at around 60K miles and has gotten progressively worse. The noise is only noticeable after a long dry spell in the weather, and sounds like a bad CV joint. At its worse you can actually feel it in the steering. I took it into a dealer and, of course it rained that day and they could not hear anything. After checking everything that they could they came back with nothing. My guess is that it's a bushing that drys out and once it's lubricated by the rain it's OK for awhile. Any help???
