loud whine noise from trans area
My 01 D2 with 140,000 suddenly started a loud whine from the transmission/ transfer case area. It is higher in pitch with speed and I can feel it in the (d1 converted) transfer stick. It is not present while coasting but is there when on the gas at all.
I plan to check diff fluid level to rule out the easy things. Any experience or thoughts? Does the transfer case have it's own fluid too?

Update; diff was good, got mne fluid in.
transfer case only had 1 quart come out. Fluid looked ok, pretty good amount of shavings on magnet, no chunks. So it must have run low and dry for too long. Put in new 85/140 standard oil .A lot quieter but for sure makes the noise.
Ignore forever or replace?
Certain oil fix it better?

I dont think any oil can make it better, once the damage is done, it's done. You could experiment and see if a particular oil makes it quieter.

It's definitely only gonna get worse. And extra metal circulating will compromise everything else so, better to repair sooner than trying to nurse it along. If you've ever seen a noisy one taken apart, you'll understand why it's so important to keep up on fluids. Even if you do, sometimes they fail anyway but low/old fluids are the fastest, surest way to failure.

Well I was hoping to limp this Rover along for less than another year. Not yet planning to dump another transfer case in to it so I guess all I can do is hope it doesn't grenade itself.
i assume as far as a proper repair a replacement case is the solution?
I feel like the magnet got the shavings pretty well but I'll probably do another fluid change soon to make sure I get all the shavings out.
Sad news for old Rover.

Run it til it fails
That is a fair amount of shavings, but no chunks of gear, and as long as you dont get grinding or any other noise, it is fine.
A second fluid change in a month or two wont hurt to flush out any more garbage in there. If you want to do one every month for a few months, that would be a good way to monitor continual wear.
Otherwise, fill it and run it. the LT230 is very stout and some whine doesnt indicate imminent death.

how about some redline shockproof lube? Sounds perfect
HEAVY SHOCKPROOF®
- Film thickness greater than an SAE 75W250, yet low fluid friction like 75W90
- For heavily-loaded racing differentials and transmissions, problem gearboxes
- Many performance racing applications like Sprint/Midget/Dirt Late Model Differentials, Detroit Lockers and spools, NHRA Top Fuel and Funny Car rear ends
- Not recommended for most synchro applications due to the product's extreme slipperiness
