Reverse Noise and Turning Noise
 

When I turn I sometimes hear like almost a grinding noise or as if something is rubbing against something? Wheel bearings I guess?

Also when I Reverse it happens in the back of the vehicle it doesn't happen all the time but it's really loud when I reverse when it happens..

turning both ways? during slight turns or at full lock?

"it" happens. we need a lot more description here.
