Technical 4x4 rear diff
If not whining or rumbling, what sort of noise is it? Very difficult to advise about noises on any forum, even videos do not present well.
With a 4x4, there are lots that can make noise.
Prop centre bearing, and its joints at each end.
If the tyres across an axle are not matched, that can cause the diff to be churning all the time. Tyres can be noisy, especially if chunky ones, and wheel bearing noise can transmit along drive shafts.
Rear diff mounts seem to be a failure point occasionally, and when failing will transmit noises that otherwise might be normal.
Everything needs to be poked, prodded, twisted and shoved to identify any wear or other issues.
Oil level might be a place to start.

Must have missed it, been a bit ‘preoccupied’
Are you sure it’s the dif, I’ve never experienced a rumble from there, I have done one rear wheel bearing and centre bearing and some drop links but, having done 150k in the panda climbing, 70k on the diesel cross I’ve not had any diff problems.
One thing I will say about the bearing is that there was absolutely no play, just noise, a definite rumble…as @portland bill says, noise can be transmitted and an empty spare wheel well can amplify that noise!

Consider doing both bearings and the rear discs at the same time if they are well used or worn as it may save a wedge in the mid term.
Part numbers
Not sure how helpful it is as there no number for the complete assembly as the bearing was originally supplied seperate
Strange I can't seem to find any new online, maybe a telephone to the main dealer and ask for a price, after being quoted say that's more expensive than I thought I will have to think about it, save having to look the part up again can I have the part number so I can quote it when I call back
The main dealer might be cheaper than expected
You might get a different part number you can find elswhere
Of cause it could be stupidly expensive and they save the quote against your reg
But worth a shot, there's nothing to loose
