So, my dad's truck has run into a problem... There's a pulley that you can see wobbling a lot and it also is very loud. We've made sure to not drive it as it really looks, and sounds like it's about to fall off. We planned on taking it to a buddies to get it looked at, but in the mean time, I figured I could try and figure out what the specific part is so we can purchase it beforehand. If anybody has any idea, or if you need better pictures or even a video, just let me know. Thanks!












The pulley that's wobbling is directly beneath this!

 

The Power Steering Pulley bolts to the Crankshaft Pulley. Make sure your Power Steering Pulley is bolted on securely. 4 bolts hold it on.

 

Just checked and all four bolts are there, they're not loose either.

 

Water pump pulley.? Is the fan connected to it?

 

It seems your pointing at the crank pulley, the big one on the bottom, has 3 groves for belts? check the bolt is torqued to spec / missing.
