All the 4.2's do it.
The 4.2's have a harmonic frequency vibration through the driveline at low revs - never used to worry me too much, but haven't had a 4.2 for a long time and you sort of forget what it is like....

Agree with previous comments. All manuals do it even from new (not as loud of course). The service manager at Nissan Caboolture- bloody good and very knowledgeable bloke on 4.2 diesels told me about the growl in the box when I bought my new ute in 2006. He also said it would get worse with age- and he was right. I think he said it was the way the gears were cut and as they are so strong and reliable, I for one, am prepared to put up with it. My son's GQ ute with a lot more klm's is the same.
Only happens at slow speed usually in 1st when crawling at under 1000 rpm and disappears quickly.
Just out of interest, does anyone know if the 'growl' is audible outside the vehicle? Can't say I ever noticed it on another Patrol.

Not as noticeable from the outside, as it is often masked by tyre noise, as well as engine noise.
