My mains electric drill makes an identical noise due to a worn rear plain bearing. Lubrication solves it for a bit then it's back.
Like I say, it sounds too fast to be at wheel speed. You mentioned front prop having play. Where exactly is this play in the propshaft? Spline? Does it only do it with a certain load/amount of people in the vehicle?
99% it is your steering. My box was loose on my old defender and I was about to offer that point before reading on. The only other thing could be a loose wheel but if the shop has had it on and off then may not be. However you crazy aussies are worse than the Russians. I've seen what you do do to your trucks on youtube and the word it MrT isn't very happy about it either...
Try lifting the prop at each end and at the slide coupling. There should be no movement whatsoever in either the slide coupling or the shafts from the transfer box or the diff. If there is movement from either shaft I would expect this to be accompanied by an oil leak from the appropriate seal but there has to be oil there to start with of course.
Haha worse than the Russians you reckon? In what sense (just out of interest)...
Have you never seen the Russians offroading! They like to submerge the truck in ice bogs and drag them backwards with tractors and stuff! Just youtube search for Russian 4x4! The aussies on the other hand like to drive full speed ( in 1st gear low) into large stationary objects mainly large boulders and vertical rock faces!
Back to the original point, it took me weeks to figure out the problem with the defender front end only diagnoses when I went through every part systematically and found the steering box bolts were loose. It took a certain speed to create enough wobble to make it noticeable but stationary you just wouldn't find it. Maybe just check your springs are seated ok as well.
Did you find out what the problem was Anton? My 80 started making that exact same noise 2 weeks ago! So far it's done it 3 times about every 200-300kms
I would check the front diff crown and pinion teeth, you could have a damaged gear tooth, my front diff used to make a similar noise at random intervals for varying times, also came under load.
problem foxed a lot of "specialists" until I broke the front diff being over exuberant with the right foot off road and replaced the pinion and crown gear, never had the noise again.
