When making tightish right hand turns eg going around a mini roundabout, I've recently started hearing a occasional clunking/knocking noise on the passenger side of the cab. Sounds like its in the cab area rather than further forward in the suspension I think. Not real bad, but I don't expect it'll get better by itself.
My current theory is that as I take the turn the passenger side of the vehicle is 'unloaded' making me think perhaps a body mount is loose/worn & that's what I'm hearing.
Can anyone who has needed to replace body mounts tell me what symptoms you noticed & how you confirmed that it was the body mount(s).
Is it feasible to replace just one or do all need doing at the same time.
Is this bent one (rear passenger side) a body mount? And if so does the nut get undone from the bottom & the bolt pulled up & out inside the cab?

iv' never done a patrol body mount before but it does look as though it has copped a hit on the bolt as well as the chassis mount bracket . if the mount is original you might want to consider replacing all the body mounts as they would all be collapsed to some degree .

Yep as above given their age definatly worth doing them all as they will all have collapsed / sagged to the same degree. Not an overly hard job but need to get to both sides so flooring needs pulling up to get to the bolt heads in the cab, front two probably need a few extensions to get down to them from the top of radiator support (not sure on GU but GQ that's the best). Will need to jack up cab to to get new ones in which will be inevitably taller than the old flogged out ones. Hope that helps could replace one but would be best practice to do the lot IMHO. .

Had the same noise not long after buying the Old Trol. The two front body mounts have been shimmed up with a temporary fix of a donut shaped bit of inner tube for over ten years. I must get around to changing out the lot, with slightly lifted ones.

I did the mounts in mine a few years back due to a knocking noise whilst turning. All fixed with new mounts.
The fronts I recommend new bolts as these will be rusted out quite badly due to going through the lower part of the rad support panel.
The second row mounts, the bolt comes out from the bottom, easy.
Third row the front seats need to be removed and the bolt come from the top.
Fourth row are on a small cross member under the rear seats, on a wagon they are, ute dunno.
Fifth row, are right at the back. Of course.
Not an overly hard job, time consuming yes,
I just used my trolley jack and blocks of wood to lift the cab up.

Thanks fellas, you've helped me to determine the way forward.

Feedback. Took car to local mechanic. He wasn't convinced that the noises were from worn body mounts, but did find a heap of worn bushes & some engine & gearbox mounts which were on the way out. Not really surprising after our past 6 years of travel with lots of corrugations etc. All replaced ($2000!) & the noise has lessened noticeably.
