Sounds like it needs some lubrication. Try applying some graphite powder.
I just went through the same thing with my 2004 Wrangler . I had to replace the rear pinion bearings and races.
Poor driver judgement and excessive use of the accelerator pedal.
power steering
Maybe the tires? If it is in the engine compartment, it is probably either a loose belt or one is getting old and slipping.
Idle set too high or accelerator is sticking and needs lubrication.
too many beers dude ..or the accelerator may be getting stuck

The purpose of an accelerator is the car is to give the engine gas so the car will move.
The function of an accelerator in a car is to increase the speed of the car. When the accelerator is pressed, the car gains speed because an increased amount of fuel is added to the motor's consumption.
Sounds like a squeaky belt to me. Did your car sit out overnight or get wet. Does it go away when warmed up. Almost always the belt.
Hopefully, all you need is to add some power steering fluid. The cooler temperature at night can make the fluid you have compress and accentuate its lack, and a squeal occurs when more fluid is needed.
It is the accelerator pedal.
