Could be a failure in a diff, a CV joint, a snapped half shaft or even one of the drive flanges. With one front wheel jacked up, turn the wheel by hand and see if you hear any grinding noises. Darren

Most likely drive flange (probably rear offside).

Take it out of difflock and let it tick over in gear, handbrake off, footbrake on, clutch in, while an assistant looks to see which propshaft is turning. Whichever one turns, the problem is at that end of the vehicle.

Oh dear, front diff. Unusual on a TD5 90 but that'll be no comfort. There are many upgrade options if you're so inclined, and cheaper than new genuine parts.

A common issue with front Rover diffs are the crown wheel bolts loosening and consequently shearing.
It happened to ours last year. Symptoms were some loud bangs in the transmission.
Oil was as clean as could be, but the diff pan contained broken bolts and pieces of gear teeth. They didn't come out with the oil since the drain hole is not the lowest point . You might want to check with a small magnet.
A while ago a bloke on another forum had all the crown wheel bolts broken, but miraculously the gears survived unscathed.
Other possibility are broken differential gear pins.

I installed an Ashcroft ATB as an upgrade. Plenty of opinions on the forum.

Yup, happened to mine (2000MY 110) as well, just as described. I was convinced it was a transfer case issue. Simple fix in the end. One bolt Big Cry One! 2010 Range Rover MkIII Autobiography Super Charged (Idris)

I too thought it was the transfer case first, so I ended up rebuilding that too. I even drove a couple of weeks with the front drive shaft only during which time nothing special happened, so the logical conclusion was that it was the TC's diff. I was almost disappointed when it turned to be OK.

Ashcroft ATB is an obvious upgrade and cheaper than a genuine LR diff, and much stronger than the original 2-gear diff.
