whining bearings on a 2uz

[angerhater]

I am getting some loud whirring sound from one of the pulleys on the serpentine belt . 230k miles not sure which pulley or pump I do believe the waterpump was replaced at 190k . no difference if I put the AC on. I am hoping its an idler or tensioner...I cant get my bad hand in there well enough to grab the things I want to check if their loose....wish me luck

take a video, most likely the tensioner..... ours started that about a year ago. New yota part was I think $100 on amazon and the design is updated with a bigger spring.

well...… lucky me, yesterday morning the whining/whirring was plenty loud. I put the truck in gear and it stopped. then started squeaking and chirping, so I investigate and see the tensioner pulley is seized. pick up a new tensioner and pulley and belt from advance. get home and manage to get the old pulley off the tensioner, great ...much less work to finish. but the new pulley is a bit smaller and the belt is even longer than the stretched old one...a trip to napa for the correct parts and now I'm Golden......
