I just got the alignment checked and it was not that bad. The toe was a little out and not in. The noise I get is from the tires on the back. The inside edges of the tires is not round. It has a wash board apearance. I had these tires on the front for too long and this is how they wore. Ran too a low a pressure also and took too many corners too fast. Not a good thing to do to Yoko AVS db's. I should have rotated them more often. Nothing is loose and all the bearings feel okay.
I actually post a similar question back in the fall and the response was..."Look at your tires" I should have listened.
