I have a 2008 Dodge Avenger that does a strange knocking sound when I start it up and while driving. I was told motor mounts need to be replaced. Before I purchase them I want to get a confirmation from an expert. I found video that someone Avenger sounds exactly like mine

Please check the video out and let me know if it’s motor mounts or something else
