Front end popping

[wade the k]

Hello everyone. I am a new x5 owner and new member to the forum and I complement the group for a wonderful site.
My x5 is making a popping noise in the front right. Happens while turning or going over rough terrain. Slow tight turns are the worse. I don't think it is the power steering pump pop I have read about.
The dealer has replaced lower control arms, and has sway bar bushing ordered to do next. He says the TSB on the Wheel Bearing is not it. Any suggestions? Are CV joint problems prevelant on the all wheel drive? I haven't seen much discussion on this topic. The car has been at the dealer a week. Any information would be appreciated.
Thanks
