whining sound when turning- WORKING ON DIFF NEED HELP!!!!!!!!
Whenever I turn I hear a whining sound that seems like it's coming from the rear end. I changed the rear diff fluid but that didn't do anything for me. I only hear the sound when I'm turning. I need some help diagnosing the problem please.

Yeah I added the limited slip. The sound only happens when the car is moving. I can turn the wheel all day while sitting still and I don't get a whining sound. Any other ideas or things I can check?

Re: whining sound when turning
I'm probably not describing the noise correctly. It's a whining / rubbing sound that only happens when turning. The tighter the turn the louder the noise. It's also louder if i'm going faster. That's why I thought maybe it was something in the differential. There's no grinding or chattering just that whining / rubbing noise (the tires are free and clear and not rubbing on anything).
I thought maybe one of the rear hubs was going? I lifted the car and tried checking to see if one of the wheels would wobble but they seemed pretty tight.

The brake pads are good. They have lots of meat left on them. Worn Posi? Man I hope not. The sound is not high pitched like brake screech. It's more like a groaning sound. the sound isn't a single constant note it almost sounds like whatever it is, is rotating.... I hate trying to explain sounds.....

Re: whining sound when turning
So the whining sound is actually more of a groaning sound. 145,000 miles. My 'guess' would be a worn out or approaching the end of its' service life Auburn posi carrier. Since you didn't say/state if rearend lube was EVER serviced,I would drain and refill to see if the situation changes any.

Re: whining sound when turning
these are the same systems of my car before the posi broke when you changed the gear lube was the old lube still fresh ? or was it black with a lot of metal shavings in it ?
do you have two great solid black burnout lines ? or is one fading more then the other ?

When I changed the oil i used regular gear oil and whatever the brand of limited slip was on the shelf for chevys. I'm going to try switching to synthetic gear oil and I'll also pick up the actual chevy limited slip from the stealership and see if that makes any difference.
