Hello all! I'm brand new to TN and look forward to poking around, meeting fellow Toyota owners and learning stuff. I have a 2008 Avalon Limited with 117,000 miles. Right around 102,000 miles there was a bumping noise in the rear. The ride quality degraded so I replaced the struts all around. The problem remained. The noise seems to be louder in the right rear of the car. I've replaced bushings and torsion bars and everything else that was worn out. My mechanic can't find the issue but said it wasn't safety related. I miss that quiet ride I used to get. Is the issue in the frame/sub-frame or chassis? Other than that, this almost 12 year old car runs like new. I welcome any suggestions. Thanks everyone!
