I have a 2014 AWD ATS that I purchased in January of 2015. I have been having this issue for months. My car only has just over 3k miles on it but the problem started with under 2k. I drive 1 mile in and out on a dirt road to my house the rest is mostly pavement and hwy. But I do have a gravel driveway. I notice the noise mostly coming down my driveway slowly…it is starting to sound like my wheels are coming off. I don’t notice is as much on paved roads. My GM dealer has replaced the knuckle joints and the front strut but the noise is still there. They have no idea what the problem is. I can feel it too. It is so frustrating. I have been doing some research and see that some talk about replacing the sway bar link being a possible fix. Has anybody had any luck replacing the sway bar link? I don’t want to keep tearing everything apart and potentially starting new problems.
