My wife's '60 rag on a '68 pan has developed an intermittent "clunking" sound coming from either the trans or the axles. There is no noise when the car is not moving and the engine is running so the problem would appear to not be coming from the engine. The trans shifts through all the gears with no grinding. The clunking noise is not only intermittent, meaning I heard it once quite audibly and then I reversed the car and went forward and it was gone, but is rythmic "ca-lunk-ca-lunk ca-lunk." Anyway, Ihave ot go to work today and cannot play with it until this afternoon. Any reccomendations on what to look for? Could something go haywire inside the trans to cause a very loud and nasty sound that comes and goes even though the trans seems to work fine? BTW, its a stock 1600 dp with a freeway flyer trans of unknown mileage.
