Re: squeaking suspension
I had the same sort of issue in my 156. My noize sometimes resembled a squeak, sometimes a clunk, usually over uneven road surfaces at low speeds. And it never really happened in the wet! I though my car had a personality where it liked the rain or something.
My ace mechanic worked out the problem when i sent it in for a well earned service! It turned out to be the top suspension arm (please correct me on the tech name for this as I'm not car mechanic). He showed me the broken ball joint and said it was shot to pieces!!
Anyway it was changed and hey presto, no more noises! Just smooth and silent! I can now have passengers in the car without having to have the stereo on full blast to hide the funny noises!
