Help diagnosing Rubbing Sound coming from Engine (1st Gen)

Hey All,

I have a 2004 Tundra 4.7 DC and noticed a rubbing sound coming from my engine today. Seems to be coming from the front of the engine. It increases with engine speed. Was thinking maybe a maybe a pulley or bearing for the fan? Any ideas where it's coming from?

Here is a video of the sound

Sounds like a bad (dry) bearing.

Pop off serpentine belt. Spin each bearing to figure out which it is.

 

Thanks @shifty` I did that and the Tension Pulley bearing sounds dry for sure. After I put the belt back on the sound seems to have gone away, but I also noticed that there is a bit of play in the Fan Pulley (it has a 1/4 in hop up and down) and I'm wondering if maybe the fan pulley bracket is going. Is a wobble on the fan pulley indicative of an issue with the bracket? The clutch seems to be fine. Here's another photo to the movement I'm seeing.

It does look a little askew, doesn't it? With regard to the fan clutch, if the truck is off and cold, grabbing a fan blade like you're going to give it a good spin for a couple of rotations, does it actually spin a couple rotations or spin for less than a full rotation? If you grab the fan itself, any play in it?

 

@shifty` it spins about a blade or two.

 

Well, sounds like the fan clutch is good at least.

 

Yeah, when my fan clutch went out it made more of a woo woo WOO WOO woo sound. That thing sounds like a diesel tundra.

 

It was the Fan Pulley Bracket. Bearing had gone, and warped the post.
