clicking noise on transfer box

Hi all
I have a l322 2003 3.0 td6 with a clicking noise when braking or slowing down on the initial push on the brake pedal.
I thought it was the brakes checked this and it still happens, so I then turned to the prop shaft as it was on the left side and sounded from behind the passenger seat. I have stripped the prop tube out splines and coupling at front end Diff are fine,rubber doughnut is ok, the coupler that centres into the flange on the transfer box is a little worn but cannot find one on line if anyone has any suggestions, but when in park and I turn the transfer box flange left to right about a centimetre play it makes the sound, I imagine this is bad I am replacing the other parts for new just to eliminate for future.
Please can anyone tell me what this is and if its bad as I have only had my RR for 4 months and its been good a fantastic car/suv 4x4

What mileage is on it Pete?

129,000 had a recon auto box at 85,000 on the device file Mark

Transfer box wear maybe?
Try disconnecting the both drive shaft ends at the transfer to eliminate them.
I don't know if there is a chain inside the L322 transfer?

Hi Mark
I have removed front shaft and you can turn the flange left to right approx. 1 centimetre and you do get a clunk . do I need to remove rear shaft from the transfer end and do the same.
If its transfer wear do I need to get a new box? is there anywhere that reconditions them?
I don't know if there is either its 03 plate

If you remove and check the rear as well, check both ends of each prop.
A little play in the power train is acceptable to an extent.
I would have it checked before paying for a recon unit!! Any l322 knowmores
