I've brought my Mustang in to the dealer a few times to have them check out the "clunking" sound the suspension makes when going slowly over rough terrain. I'm convinced it's the problem where the front strut mounts need to be replaced which is covered by TSB 07-18-02. However every time I've brought it in they claim they don't hear anything and as a result don't fix anything. Is there any way I can get the dealer to perform the TSB anyway? From what I've read of other's experiences the sound I'm hearing has got to be the same problem.
