I have a '94 Explorer Limited, 4.0, Automatic. A few months ago I noted a light clanging sound every once in a while from under the truck. Over the months the clanging has become evident more often until now it is there almost all the time. The truck is normal in all ways except for the clanging. Today a mechanic listened and said the sound was coming from the bellhousing. Hmmm. He said he thinks it may be a bolt coming loose and hitting on something. Perhaps one of the bolts that attaches the flywheel to the torque converter. If he is correct he thinks he may be able to tighten the bold through the starter motor opening. Has anyone had this this problem before? Any comments or suggestions?
