I have a 2016 ST and about a month ago whenever i start going in reverse or in first, im hearing a nasty clunk noise. only happens when i first start to move maybe after 2-3 feet of travel. I've read other posts on front end clunks and nothing similar to this. It also sounds like a creaking noise after I slow to a crawl like something is moving back in place. I recently installed a cobb rear motor mount before this started happening.
