Classic Drive belt idler pulley making noise

Started the car to go to work this morning and heard an occasional grumbling rattle. Put a listening tube to all the spinning parts and it's coming from the belt tensioner idler pulley.
Can I just replace the pulley or do I have to replace the whole tensioner unit? I ask because I can only find the complete unit for sale here in the States, but so far I can't find the pulley alone.

If you can do without the car it may be worth stripping it down and see if the bearing is replaceable.

It's our only vehicle. How crazy is that? A 1995 Range Rover as a daily driver.
I know, I know.......

My last Classic was the only RR that I had faith in to be able to complete a 5000 mile journey from home through France, Andorra to Southern Spain and back.

Perhaps I'm a Range Rover whisperer. Removed the belt to spin everything involved. I found no sign any bearing problems. No weep from water pump. So then I tried to put the belt back on. Which took a long time. Finally after cussing and praying, I got the belt on. Started the car and no more sounds. After driving around, still no more sounds.

If you need to have your Land Rover repaired, ship it to me across the pond.
