Speaking of whines from the rear...
...mine only makes a noise when turning a really tight turn at slow speed, like in parking lot manuvering. I seem to recall the i hear i more when backing up than going forward. I just cant remember right now. The sound only gets my attention cause it reminds me of the same noises i get when turning tight radii in my '93 Ranger 4X4 with the 4x4 engaged and it also reminds me of a power steering pump howl when turning a car at full lock at slow speed, but not quite as strained.
BTW- I have no idea if i have LSD. I thought i would do the spin the wheel test when i do the brake pads.
Anybody else get the same noise in slow speed?

John,
It sounds like your differential plates (posi - rear) are sticking. Thus allowing no differentiation between the inner (slower) and outer (faster) turning wheel when making tight turns or the differential gears (spider gears) are worn, bad or dry.
Change your differential oil; make sure it’s for limited slip differentials only.

John,
Different animals.
About once or twice a month Pattycakes will give me a strange, push from the right rear wheel on a sedate- granny- slow, flat, turn (90^)onto a side street. No noise, but the push is like someone pushing firmly, but, not hard on your shoulder from behind. Kinda like the sprag gear on an Army
Deuce and a Half being wound up and letting go on a turn -without the bang-.
I'm with Steve on the fluid change. When they whine like that in West Texas pick-up trucks its, generally, to late. When you change the fluids stick one of those telescoping magnets - $5.00 at the auto parts store - into the disposal container and see what you come up with. If its no more than a tablespoon of granular cast iron looking sediment I wouldn't lose any sleep.
If it's thin shiny, chrome looking stuff you have a problem - find another rearend preferably mated to the original trans. After that wait till it goes or gets a lot louder. Though, in some cases I've taken apart there was no fluid just a heavy paste of ground bearings/races, and what have you. The driver would always say that it made some howling noises a few months ago but got quite all by itself...go figure.
LOL/HTH
