The bolts that hold the vibration damper onto the rear of the transfer case (near the hand-brake drum) could be loose.
I noticed a metallic rattle - I was thinking it was like a loose metal guard on the exhaust or a baffle in the muffler - but it seems to be coming from the transfer case, but its there even when the auto is in park. Have just on 200K and no known work on the transmission. Drives fine.
Cannot hear it driving, but it is a TD5....
any ideas? Thanks

Could possibly be the handbrake shoe retaining springs getting weaker and allowing a bit of buzz in there.
If it has a bellows style of flexible section in the exhaust pipe just below the turbo then the flexible section may have stretched which causes a rattle from its internal limit stop. Lifting the exhaust from below the joint whilst idling will silence the rattle if this is the cause, for which the permanent fix is to have a wire style section fitted which will also improve exhaust flow considerably as the flexible section has almost a 50% restriction.

Ok - thanks for those suggestions - I will have another look later today - when I won't wake the neighbours!
As said check the exhaust flex joint, some have had rattles from them.
Also check the heat shield over the centre muffler hasn't come loose, my RRC classic rattles from here.
Also look at the turbo heat shield, the rear mount is a known rattler too.
Good luck.
And the heat shield from the LH transfer case rubber mounting can be very noisy too if it is broken and vibrating or even touching the exhaust pipe as I have seen them drop down when cracked.

Centre muffler heat shield will make a racket if that is loose. The clips work loose. If you have a look on the RAVE cd there is a bulletin which recommends replacing the clips with a flanged nut. It's m6 or m8 - I just used flat washers and nuts and put thread locker on the nuts.
The flex plate when cracked will also make a metallic rattle, mainly at idle. You won't hear it at revs or the frequency increases to above audible. I had it at idle and chased it but fortunately the auto failed first.
