My truck sounds very loud when I start it up and gets louder when I accelerate. When accelerating I hear a sound like metal in spokes if that makes sense. It has no power anymore either, especially going uphill. I can't get it to go past 50 MPH when it used to go at least 80 MPH easy. The transmission is shifting hard as well.

It sounds like your clutch fan is locked up, open the hood and without the engine running turn the fan clutch it should have some resistance but turn smoothly.

here are two guides and a video to help us fix it:
