Back with another problem. I turn on my printer and the fan makes a loud noise on the extruder. I turn it on and off but still very loud. Could It be hitting something and if so what do I do?

Either it’s dirty or it has to be replaced.
With the printer off, take some canned air & shot it into the fan.
Replacing a fan is pretty straight forward, but you have to save the old plug. Most 4010 fans come with bigger plug. So you will have to splice the old one in.

Ok. I will try that. I am sorry I did not specify, if this does any thing, it is the fan on the side. I will still try what you said to do though. Thank you!
