Crux...
Along with the "clunking" I was also noticing a high pitched whining noise from the rear end when at speed (approximately 60 mph).
This noise along with the clunking is what really tipped me off that there might be a problem. When they checked the service records on my car (since I just purchased it) they showed also that mine had been in for the recall work. However, they said that the only work completed on mine was the installation of a new differential vent and a new seal. It is my understanding from what I have read on this forum, that there are a few other parts that need to be replaced as part of the recall and the following bulletins.
My dealer (Saturn of Avondale) seemed to be very aware of the differential problems and even told me when I dropped off the car that chances are that the differential would need to be replaced. They had to do their diagnostics first but they seemed to be already aware that it would need to be replaced.
Not sure why your dealer is being so resistant to admitting that there might be a problem with your car. You are right... you may very well have a "broken" car soon. Mine right now until they get the new differential delivered is clunking so much it sounds like the rear wheels are going to fall off. They changed the fluid in the differential until the new one comes in so that they could ensure it would be ok until then.
I had always heard that Saturn was such a customer service driven company. Was not very satisfied with their sales department (why I ended up buying mine from a chevy dealer) but the service department is top notch.
Do you have another Saturn dealer in the area that you could get a second opinion from?
Good luck!!! I will let you know the outcome of my differential swap once it is completed.
