So like many others, i had a noisy bearing issue under the hood. I described it to Roadie and showed him. He said it was the same one he had. And that it was the idle pulley. It was much hotter then the others. I told him that I had replaced the belt and the Belt tension pulley. I showed him and he pointed out that I had missed the Idle pulley. Silly me i thought It was on the Tension pulley assembly.
So today I went to Pepboy's today and picked up a Serpentine Belt removal tool for $22 (It worked great! fit right in, even came with a socket head to remove the bolt on the Idle pulley). And the Dayco replacement pulley. The replacement parts looks and fits exactly the same! Such an easy install. It took a buddy and I about 5 minutes to take out the old and put in the new. Now my truck runs sooooo quiet! All I can hear are the noisy injectors hahaha.
I love that the whine is gone. I got so used to it for soo long that I didnt realize how loud it was till I fixed it. Now I can actually hear what the truck sounds like with my resonator delete mod.
