Dry ball joints/suspension joints.
Universal joints going bad.
Worn brake pad "squealers".
If your car makes a squealing sound when you are turning it is because your brakes have worn out. When the brakes wear down below a certain point, a wire pops loose. That makes a squeaking sound.
You should check the struts.
te alternaor belt may be slipping causing the squeaking as it returns charge to the battery
sounds like you need new belts Your brake pads could also be wet
Defective rear shocks. Loose exhaust components.
c
An old belt getting wet. Get it changed out.
Lack of lubrication? worn suspension parts?
Dirty brake pads could cause a car to make a squeaking noise when putting the car in gear or when releasing the brakes. Cleaning, sanding, or replacing the brake pads should make the sound stop.
The high pitched squeaking noise you are hearing is the warning device telling you your brake pads are worn out and need replacing. The grinding sound is the sound you hear when you ignore the squeaking noise and allow your brake pads to wear so much that the metal backing of the pad is rubbing against the rotor. Replace all brake pads on the same axle and have the rotors turned at a machine shop. You may end up having to replace the rotors if they are damaged too severely.
that probably means its time to get a new car
MAKE CAR MAKES THE SAME NOISE AND REPLACING THE PVC VALVE FIXED THE PROBLEM
