really loud vibration with slight judder

I checked and yes the woo woo has also decreased to barley perceptible. Basically it seems any weakness in the drive gear, mounts, or anything else contribute to noise.

I noticed the 2 mounts that support the transfer case look a bit rotten, see pics, I'll replace those next and see if there is more improvement.

I had the hubs off the other day and they look fine, no wear or water. I had a good look at all the vacuum pipes and nothing obvious there. Checked the appropriate fuse under the dash. Maybe an electrical problem? This is regarding my other problem, 4x4 not working as the hubs aren't engaging.

Does the square metal backing contact the metal on the transfer mounts....makes a strange noise on accel?

did you make sure the hubs were totally clicked back into the hub housing
and check the splines on the ends of the shafts ?

not long ago when my vac system was failing, one of the hubs wasn't quite disengaging and it gave a similar noise as it chewed the ends on the spline on the shaft.

hope this helps

Before I fitted a new gearbox mount I would get a high pitch whine on acceleration, the noise disappeared after fitting the mount

I didn't really check for that, I'll take the hubs off again and check, though with 4x4 engaged with engine running in neutral I did the check where you jack one side at the front and check for lock, then the other side and both wheels free spinning without any resistance or noise, while the front prop is locked as it should be.

The flashing 4x4 light, which is on in my current jimny, isn't that reliable as a sign of vacuum fault as this was flashing on my last jimny yet the 4x4 worked fine. I would have liked to sort it out rather than manual hubs but I'm starting to think it's an electrical fault and perhaps too complicated.

Oh No! ... what's a photobucket victim?

At the end of the day I always think the manual hub is the way to go.

Photobucket has turned to a pay site. If you do not pay and your account is popular (views above a certain limit) you are cut off.

And I have threads all over the ether with loads of pics. Maybe the worst hit of mine is the POCUK site where my Pajero threads have now lost the lot but hey, that site refused to use its own hosting despite my moaning about it so it is divine retribution in a way.
