My recently purchased 96 Disco I has developed some new noises over the last week. As I come to a stop I hear a distinct click as if something is loose when the vehicle is slowing. Initially I thought the jack was tapping the back of the headlight housing. this wasn't the case however. When I slow to about 5-10 mph it makes the noise. any opinions and advice to fix?

The Clunking i am talking about occurs when i shift the transmission into drive or reverse...(obviously an automatic) at a stand still. Is there anything I can do to eliminate this noise? I feel like the gear box is going to fall off or something.

Any takers!!!???
