Whinning noise commig from left corner
So this happens every time I drive now. After I drive for about 5 minutes something starts making an electrical whining noise and it sounds like it's coming from the driver side. It gets worse and high pitched when I accelerate and when I turn it gets louder. I can almost feel it in the steering wheel as if the wrong parts are rubbing together. Had anyone else had this problem???! It's getting super fricken annoying please reply ASAP! It just started and has been happening for about a week

Sounds like either a wheel bearing is starting to crap out or possibly driveline also.
If you open the hood and rev it does it still make the noise? Jack up the front and at 12 and 6 on the wheel shake it up and down.

Sounds like a good plan. The noise is still there while not driving, so have a good look and listen and you should be able to narrow down where it comes from. Let us know what you find.
I found out that it's definitely coming from the power steering pump. I've read about pumps getting clogged and pulpy getting loose which could be a cause for the noise. Lmk what you guys think

Check the level of the power steering fluid first. If low, top it up. Power steering fluid is something that's often overlooked as fluid that needs replacing as well.

It may just be (very) low on power steering fluid. The cap for the power steering pump should have a plastic dipstick attached to it that goes down into the fluid reservoir with marks on it to show the fluid level. See if it's low. If it is, put new power steering fluid into the pump until it reaches the correct level on that dipstick. Then crank the car and turn the steering wheel all the way to the right, then all the way to the left, back and forth several times to make sure you burp all the air out of the pump. Sometimes you can't get all the air out of it at first, but driving it a day or two will work any residual bubbles out of it, and the steering will smooth out.
If that fixes your issue, you will likely want to check the power steering fluid level fairly often. You probably have a leak, but you can nurse a leaking power steering system along for years if you keep the reservoir filled. I kept mine going until it was literally spraying fluid from the pressure hose.
You will also want to keep an ear open for that whining noise, as that is an early warning indicator that you are low on fluid and need to add some. I'm guessing it has been making that noise for a while, and you've been ignoring it. Now that you've run it low on fluid, it will likely make that noise faintly all the time even though it's still working, but now that your ear is attuned to it you will be able to notice changes that tell you that you need to add fluid.
If adding fluid doesn't fix your issue, THEN start looking for other problems. You may have burned up your pump by running it without fluid, but power steering pumps are surprisingly tough. It's an easy replacement, though, if that becomes necessary.

once you topped it up, you might want to " bleed" the air out.
Lift front of vehicle, put on jackstands. Slowly turn steering wheel left and right, lightly touching the stops. Do this about 20 times (according the FSM regarding this) and check level. Top up if needed. Repeat and if all good, lower vehicle.

Now keep an eye on it. It will probably lose more fluid over time. But like I said above, you can nurse a steering pump along for a long time.
In my case I had a leak in the high pressure hose. It started small and grew until it was spraying fluid onto the downpipe out of the manifold and causing a lot of smoke. I got another hose and swapped it in ten minutes, and the leak was fixed. The same pump is still in there and still holding fluid.
