I should have followed up on my last posting regarding the suspension noise. I went to another mechanic and he immediatley diagnosed the problem as bad sway bar links. He replaced the the sway bar and links and the clunking noise was gone. Sure glad I didn't listen to the first mechanic and paid for new ball joints only to find the problem was still there.
