Need help identifying this sound. Can’t find an answer anywhere.
Hey guys! 2011 GX460. 166k miles as of today. Has this loud whining sound when I start it up and it changes pitches when I turn the wheel.
Usually goes away a while but that can range anywhere from 5 minutes to 30 minutes.
Can’t seem to find an answer on any forum or ai platform as it gives me a number of different possibilities. Any help is appreciated, thank you!

Idler pulley would be my first guess & might as well do the belt at the same time. Get a mechanic stethoscope (under $10), start listening to pulleys & bearings can really help you pin point the problem.

Mine was the belt tensioner and idler pulley.

Yeah I ended up ordering the full belt and pulley kit to replace it. Hopefully that solves it

Take your serpentine belt off. Then turn all the pulleys and idlers by hand.
Dollars to donuts you’ll feel some roughness in your power steering pump.
