Noise coming from drive motors in and out of turns

Hey, anyone seen or heard on a 4500AC a bearing noise coming from both drive motors going in and out of turns.
Is this normal? Maybe brake rotors floating on a splined shaft or something inside the drive unit? Anyone have a TSB on this?
Anyone run into this?

Thanks for the feedback.
I don't have a pdf file for this unit do the brakes come apart easly? I'm beginning to think it could be something to do with the brakes. Thanks again.

I have seen bad friction pads cause a noise. Easy to look for. Otherwise probably a drive unit.
No TSB that i can see.
