I’m getting a clicking or popping sound from the front end of my 2014 Fiesta ST. It was fine Sunday when I did my second autocross of the season but on Monday afternoon I first noticed the sound and it’s getting more frequent. It seems to be coming from the left front but could be anything from suspension issues to a heat shield. It almost sounds like a minor ping/backfire but it still does it with the engine off so it’s obviously not that. FYI I have Koni shocks on the car and 70,000 miles overall. I do race it occasionally but only about 10 events a year on average. So far I’ve retorqued the lugs and done a quick inspection for loose or broken bits and not found anything. I’ve thought about taking it to the dealer but I am concerned that with the Koni shocks they might not be able to fix things if the issue turns out to be shock related. I have another mechanic thats into building race cars in addition to normal service but he’s so booked up right now I can’t even get him to pick up the phone.
