Default Suspension noise - this one really has me baffled

Hi folks. Got a prob with my 05 conv. turbo. About a month ago I was hearing bearing noise, so I took it in and the shop replaced the drivers side bearing. Problem solved only then I was hearing on the passenger side. Back to the shop to get the passenger side done. I was still hearing the noise. I knew it was still the passenger side because when I steered to the right the noise would go away. My first thought was the shop didn't replace the passenger side bearing. So on the weekend I replaced the passenger side myself and personally pressed the new bearing. (the shop did put a new bearing in that side, but I changed it just to make sure). Still have the bearing noise??? Next I rotated the tires, front to back (tires are fairly new with less than 5000 on them). Still have the noise. Checked the rear bearings. No problems there. I have looked at the half shafts and they look fine. I would have lost money on this one because I wouldve bet that it was a bearing, as that is exactly what it sounds like. I have had it up on jackstands and ran the suspension without the wheels on it and just can't find the issue. The next step is to replace the lower a-arms (the rear bushings are looking a little ragged) and get it aligned. If that doesn't do it I don't know what else to do and I really hate taking it to the Mopar dealer Any suggestions?

Under the rubber boots on each side you have the CV joints with plenty of gears and a little dirt from a tear in the boot will cause almost the same kind of noise as the bearing.

Have you looked at th break pads? Rotors? Are the shims broke in half?

The cv joints are certainly suspect, i just have never heard one sound like a wheel bearing. The noise is tied to road speed so that would be on the list. I just dont understand why unloading the pass side would make the sound fade out as you increase the turn? It is baffling.
I replaced both brake pads when we did the bearings.
Do you think that it could be alignment. I would think that I would be seeing tire wear if that was the case.
Thanks for the replys!

You have bearings in the transaxle. Your axle inner shaft plug right through them. they turn at road speed! Also what about rear bearings? Just a thought.

One other thought. Flaking rust on the rotors can build up and rub caliper bracket & can be affected by turning. Really I had it happen. Look for rub marks on bracket or caliper were nothing should be touching
