It is wobbling and making a knocking sound. Last week when I raised the rpms you could hear the fan really loud. And this week that stopped and it started the knocking sound. If you look at the fan while the motor is running you can see it wobble. And my temps starting getting higher then normal.
I know the fan is part of the problem but I will also check out the water pump. But I can grab the fan and wobble it from the front of the truck to the back a pretty good bit. It is really loose. Thanks for all of your input.
If all else is good, and it's definitely the fan/clutch that needs to be replaced, swap it for a fan from a Ford Explorer if you don't want to switch to an electric fan. There's details on this at JTR. <-- (Click and scroll half way down)
