Default Whining noise on the rear diff. -240 N/A 1993 AT-

Now that the car is on use, now I realize many things not noted before.... Obvioulsy because most of time was parked.
So after all the injection issues solved, I note the car makes a "screech" coming from rear, when it turns on corners and when down hills (I'm ok?) .
Did some research, the rear differential is whining.
My little research was about the noise.
I dont know nothing about differentials, just basics and function principles, but in Volvos is my first approach.
Some owners recommend change the oil. Which one fits for my car? There is a procedure? How to do it? Is an DIY task?
Thanks masters

Make sure it's coming from the differential. It's likely that it could be the center support bearing for the driveshaft.

I have read about the whining on turns... The center bearing can do this too?

Like turning left or right? I would assume that's coming from the front end of the vehicle, but I'm not sure. Perhaps a video would help some people on here tell you what it is.

Nothing complex but was scarry noise
