So today is the first day I drove without my radio on...long ass weekend haha. I noticed at low speeds a ticking/knocking noise? It did it whether I was accelerating or slowing down. Very weird, I have been in the service side of the automotive business for quite some time and never herd anything like this. I may be overreacting but it sounds different to me. If any of you have experience with ford the input would help. I haven't brought it into my shop yet to make sure everything is tight but it's a very low faint knock.
