After researching this topic to death, it looks like it could be a number of things. CV joints, axel, rotor, pads, etc. I don't think it's the CV joints since the boots are fine. The dealer has offered to turn the front rotors for me, and I'll have them put on some OEM pades too. Of course they don'e want to do the work if I'm not going to buy the car. I think it's a nice gester on their part because they could easily put it back on the lot and sell it to someone else the way it is. So I will tell them to turn the rotors and hopefully that will be it.
