Thanks for all replies. I did the turning wheels by hand and trying to see if I could feel anything loose of excessive play, also ran it on jack stands but couldn't hear anything. Maybe it's only under weight when the tires hit the road. The noise is not real evident only hear it with windows down but definatley comes for the rear. I bought 2 sets of rear axle bearings and seals and will attack the bearings this WE. Hopefully the noise will go away. There's nothing in the brakes that's rubbing or loose, no stones in tires, and I don't believe the noise is coming from the differential or U-joints. Will post results after bearing change.
