Belt tensioner arm and idler belt pulley. Good vid bad sound. 2006 Dodge Charger.. The audio sucks cause I have the mic taped over for skydiving. So I TEXT over the important parts. Good visual if you have never seen it.
I think that the wheel on the "arm" is replaceable.
I replaced the drive belt tensioner and idler pulley on my 2006 dodge charger at 75,000 miles because of a winy noise. I changed the power steering pump 3 times before that. still no change. At idle its's quite, under load it whines. also new belt, power steering hoses x 4 and a rebuilt steering rack.
I think it is the water pump that is whiny.
It was the wrong power steering fluid on my part. You must use "Power steering fluid + 4" the "Red stuff" I bought it at the Dealers. I Replaced the fluid and the winy noise is all but gone. Probably hurt the pump by using pure synthetics? Going to drive some and flush one more time.
