When I am accelerating, I hear a creaking of what I think is the spring, but what could be causing the spring to creak like that. Once I get above 15 miles per hour, no matter how hard I accelerate I dont hear it. Sometimes when hitting pot holes I hear the creak. I have sprints by the way. Could it be just dirt underneithe the spring. It seems more than that. Like a hard creak. Whats everyones input. By the way its the front left spring I think.
