Answers :

It sounds like the bearing is going out and when you connect it and disconnect it this places more stress when it is on thus cause it to scream .It still can work even tho it it screams but one day it will go out and you can get stuck broke down.FIX; I would take it to a qualified shop and have them replace it or you can replace it yourself just be careful to note where the wires go.Thank you for your questions
