Hey,
So I made this video showing how to swap out the GM sway bar end links. I have heard many other 6th Gen owners having issues with their end links as well. The nut on the passenger side was backing out after I would tighten it up, causing a "clunking" noise going over bumps. If you are having this problem these BMR end links may be your solution!
Also have heard of these same parts actually bending under hard driving. Not what you want! The BMR links are also adjustable, for all my hardcore track drivers.
