    Guys, my truck just started doing this today. I found a video on youtube that has a similar noise. Mine mainly does it during acceleration? Any ideas? I have the tundra care so I can take it into the shop.

    That's what I'm thinking. I just turned it back on and accelerated. it didn't' do it as pronounced. I didn't notice a lot of movement in the belt. Going to let it cool off and try it again later.

    Glad you got it figured out before I ended up saying it was the engine screaming and begging for 1.1 more liters ;)
