Not yet, I'm going to remove the turbo shield first. Will do this tomorrow night.
Ours also has a nasty vibration that comes and goes. The rear tyres (Khumo) are distorted and need to be replaced so that is obviously a suspect. There is an intermittent 'thumping " too like travelling over expansion breaks in the road. Sometimes a clunking and feels like the handbrake is being applied slightly but quickly. Having done the handbrake 20K ago I have just had a look inside and it seems perfect. Uni joints good. Engine and transfer case rubbers look good. Transfer case needs top-up. Getting that today.
"the vibration damper on the transfer case and also the heat shields on the mounts " as mentioned by Outback 1......Wot is this?
Thanks, Pete
PS Vibration ceases (for 20 to 120km) if I stop, roll gently backwards and apply the handbrake.
The vibration damper is the triangular shaped weight behind the handbrake , and the heat shields are on the lh gearbox mount as well as lh engine mount but if you apply the hand brake and it goes away for a while then I'd be revisiting that . On the backing plate where the shoes rub tends to wear away , so it can be removed and re welded, this is assuming you have done the modification to the shoes and springs.
Jazzman have you found your vibration yet?

I did not notice wear on the backing plate. I don't know about mods. I put it back together as I found it. How can I tell if the mods have been done?
Thanks
I did a service on my car this weekend. Started a 3:30pm Sunday. Supposed to be a normal filter and oil change with grease of prop shaft as per usual. After this I was going to investigate this vibration.
However, I found a bolt was missing from the front of my transfer case. I replaced this bolt and checked the fluid level.... measured SFA. So i put about 1.5lts in there.
After this I decided to check my rear diff as i was told by two people it appears to be weeping out the filler hole.
Turns out the cross pin for the spider gears had dropped out the middle section but the ends were still in the spider gears. The spider gears are damaged.
Replaced the rear diff with my rebuilt spare and it also gave me the opportunity to fit the axle o-rings i'd got from Mario months ago.
I'll be listening for the vibration again now that some major components have been re-oiled and replaced. I didn't really get an opportunity to investigate the vibration sound of the weekend.
I had done my service and replaced my diff by 7pm. Including 20mins of travel time for stuff. Not bad I reckon.

On top of this where the shoes rub on the backing plate tend to wear the metal of the backing plate down causing the same as well as possible sticking
Quoting from my earlier post:

A 5000 km later and all is well. For the record, and in case it is of interest to anyone else with similar symptoms here is my follow-up:
The Khumo tyres on the rear had delaminated so badly the tyre guys clustered round in amazement that we had actually driven there. New tyres all round. A shame as there was some life left in the tread.
Transfer case was dry. Topped it up. Luckily the filler plug shifted OK but I have not been able to shift the drain plug. Can I just keep putting a longer bar on it? Anything likely to pop if the plug wont budge?
Anyway, all symptoms have gone and no recurrence. TC seems to be holding together after such awful treatment.
Great venue here for advice. Thanks to all.
Vein in your forehead?
