Two weeks ago the dealership replaced the front thrust link bushings. Today because I was hearing a clattering in engine area, I was told that left catalytic converter needed to be replaced. It is just coincidence that after the work done two weeks ago in same area as catalytic converter and now catalytic converter is clattering? Yes, I do now have about 111565 miles on my 2003 C240.
