Hood hinge spring.

slot is peened, or should be.
grind it out.
Thats what I did... unwound the spring 1/2 turn and peened it back in.
Yes this one is peened, was not sure if I should remove them. The reason I am removing the spring is because my hood is very hard to start the closing process. Thinking I should open the springs ,and lightly sand in between them. Hope this will help the springs smoothing out.
