Sway bar link came apart. Easy fix. Advance auto has them. about $45. it attaches to the Strut. Two bolts, keep in mind when the wheel is off that you might have to put a jack stand under the knuckle to line up the bolts for reinstallation of the new one. Start with the lower bolt and secure then line up the top part with the strut. hope this helps, replaced 4 in my G6 over the 13 years.
