Tinkling chain-type noise ?

Jimbo:
Td5 Disco, just under 60k on the clock (and it's an auto).

Over the past few days I've noticed a 'tinkling' type of noise from the transmission/centre console area. Seeing as I have loads of junk/coins/keys etc stashed there I thought it was just that - until yesterday when I cleared all the junk away.....the noise is still there.

The noise is present when the engine is under light load - and as far as I can tell, in all gears - except top once the TC has locked.

I've checked for obvious oil leaks, nothing seems to be leaking too much, and everything seems to be working ok (gear changes up & down ok) - had a quick look underneath yesterday, there's nothing hanging loose or caught up in the underpinnings that could make this noise........so I'm suspecting that something in the main box or T-box is not as it should be  :?

Any suggestions as where to start looking, or what the problem might be ?

I think I'd start with the propshaft U/Js at the transfer box end, both front & rear. They can make that sort of noise when they are lacking in grease and are warn because of it.  :wink:

I hope it is something this simple - I was thinking that the auto box was about to self-destruct  :evil:

I'll have a delve under later today and see - the props should have grease nips on them, yes ?

Yup, but not the ones in the Cardon joint . . . .  :(

Ask me how I know  :wink:

Remember to chock the wheels and release the handbrake, otherwise you wont know if there's any play in the rear shaft.  :wink:
Also, make sure all the diff & transfer box flanges are secure, just in case one of the nuts has come adrift.
