Suncore Quick Strut

I am on my second pair of these struts for my Focus ST. No issues with part fitment, but the part within 2 to 3 mouths time started loosening and you could hear it bouncing up and down on both sides. The right hand strut's dampener popped out during driving. I was still under the 1-year warranty so Advance Auto was able to swap out both parts out for new ones. They had outstanding costumer support. But the new ones after about 3 mouths, the right strut was starting to make the same sounds. This time I went a head and check the assembly bolt that can be accessed under the hood with dissembling the metal strut support. I tightened the nut and the noise went away. I would not recommend buying it unless you absolutely have to. Hope this helps anyone.
