Sound from Driveshaft
When I release the accelarator while on the move or when the auto is downshifting by itself as I am slowing down.. Has this"Clong Clong" sound? Could the propeller shaft be loose or do I have a bad flex disc coupling? Thanks guys...

Yes,
I would inspect the flex discs. The holes can elongate in the disc(metal) which will allow a loose fit with the bolt and a clunking sound. I'd check them first. I think the diff end ussually goes out in about 1/2 the mileage as the transmission. Michael

BlackBeauty,
Dittos on Samian4 concerns about checking the flex discs. We have had a worn front disc break, hit the transmission tunnel hard enough to set off the airbag. Please check the discs visually and physically by twisting the driveshaft and observing looseness. Pay attention to both end of the driveshaft. Fronts have been our main wear item, but both do wear and cause problems that you descibe.

That sounds rights. I noticed a small crack on the flex-disc coupling a few months ago. In fact the rear flex-disc also had a small crack. Thanks for the input guys.

In addition to the flex couplings, the rear drive shaft leading from the rear diff to the tyres can also wear to give that clonk.
A worn trannie can cause all the above, and if that is the underlying problem it may be best to fix the transmission before doing the rest. Been there with my autobox and ended up with a trannie overhaul before I eliminated the problem. Hope this helps.
