Power Steering belt slipping?
The cause of the squealing sound is because you are turning the steering wheel completely to the right or left
Turning the steering wheel farthest left or right for a few seconds will cause a loud squealing.
Power Steering Fluid Or Power Steering Pump
A loose or worn belt. Also check the power steering fluid.
Could be a worn belt, failing power steering pump or low power steering fluid.
It is very hard to turn the steering wheel and/or a whining or squealing noise when you turn the steering wheel.
Many things can cause that, the simplest cause being lack of power steering fluid.
Low steering fluid can cause a steering wheel to whine when turning. A worn steering belt can also cause a steering wheel to whine when a car is being turned.
if the pump has failed completely it will cause stiff turning, obviously not being assisted by power. if the pump is failing there may be a squealing sound when turned in either direction. This is not to be confused with the squealing made when turning the wheel to its limits.
The steering wheel will be harder to turn. First sign is squealing when turning, but why don't you open the hood, unscrew the cap on the steering pump, and look.
Turn the steering wheel right to turn right in reverse.
Positive camber can cause all sorts of issues but not a tight steering wheel.
