Whine From Car

Whine From Car
Ok having two seperate whines coming from my car.
One is RPM related and is especially noticeable when the wheel is turned. Pretty sure this is just a power steering issue. Just got back from vacation, so obviously will bleed the system and check the fluid level.
There is another whine coming from the car that is speed related. I tried searching but found nothing. When the car gets above ~34 mph a high pitched whine that is related to speed starts. Below that speed there is no noise. What could be causing this? Is it wheel bearings, or something else?

I know it's been awhile.
Weather here has been awful and been driving my ****ty buick.
Today was the first nice day and I took care of the power steering issue, so obviously the RPM noise with the wheel turned went away.
Just bled and burped the system.
Had the front tires off the ground and they both rotated freely without making any noises.
What could possibly cause a high pitched whine that ramps up with speed?
The whine starts around 34-35 mph and the pitch of the whine increases with speed.
It's very high pitched and is not related to RPM at all, it is only related to the speed I'm driving.
It sounds like it's coming from the front of the car and is more audible with the windows up than with the windows down.
Has anyone ever even heard of a problem like this, or could anyone even point me in directions to investigate? I'm still a noobie and I'm a little stumped by this one.

i have a whine too, around 25-30 mph. it's also speed only and sounds like a high pitched hum, doesn't sound like metal or anything.
mine also stops after that speed, it's just this small window that it whines at

Before you mess w/ the diff, do what Vrank mentioned and see if the wheel bearings whine upon rolling them.
Is this kinda what your SC is doing?

Also the first time I jacked it up I just rotated the tires and didn't hear anything, but earlier today I jacked it up again and tried wiggling the wheels, the two front wheels will wiggle from side to side just a little bit, but won't wiggle at all from top to bottom.
That means the wheel bearings are going out right?

Also I should mention that I hit a dog going ~85 mph on the freeway. It seperated my tire from the bead on my rim.
The next time I drove it was when the whine started.
Also about a day ago there is a rhythmic clunking that started whenever the wheel is rolling. It's audible from 0 mph all the way to ~30 mph.
Could there be another suspension componenet that would create a rhythmic clunking and create play in the wheel from side to side but not top to bottom, or is it pretty much definitely gonna be a wheel bearing?
When the tires are lifted off the ground there is no noise when rotating the tire, but when driving the clunk becomes apparent.

So just an update here.
The rhythmic clunking was 3 broken wheel studs. After I replaced those the clunking and the whine went away so I assumed the whine was also coming from a crack in one of my wheel studs or something like that.
But it's just gotten cold again and the whine has returned. When rotating the wheels by hand there is no audible noise, is it possible it could still be a wheel bearing and I'm just not rotating it fast enough to hear it by hand?

the cold, the harbinger of noises. my car just started creaking like an old house as soon as the temperature went below 40 lol. i need to get an audio system going so i could ignore these things better. it's usually really stupid things that need grease or something, but sometimes, just sometimes, it's something a little worse. that whine i had at 30-35mph has been gone for a year since last winter and i just heard it again today. it's the weirdest thing and i have no clue where it's coming from. i guess the cold just does weird things to components and makes them whine.
i'm interested how you drove with broken studs? were they just cracked or wat was going on? i might look at mine cz i have an awful grinding/clunking noise in my rear passenger wheel that's been around for a year now. it's gotten worse lately but the entire summer was nearly gone except maybe a few creaks or chirps. old cars man, old cars...

It was painfully obvious what happened once I took a look at the car, replacing those studs was a real pain since the three that broke all broke right down by the wheel hub so there wasn't much room to get leverage and I had to hit them with a chisel to pop them out, and tightening the new ones down took forever. I think I'd rather just buy an entirely new hub assembly than replace wheel studs next time, especially since I'm leaning towards this current whine being a wheel bearing... but lol I really don't want it to be as I still need to get new Supra LCA's as my ball joints are showing some wear.
