This ball joint was the same as the OEM joints that were in my 2004 Trailblazer. Box says made in Korea. The originals were still good, even the boots after 120,000 miles, but since I had already purchased them and I had the steering knuckle off, I replaced them anyway. These are exactly like the OEM joints, no retaining clips like the aftermarket one. You have to pean (not difficult) the lip on the back of the ball joint after you press it in to retain it. This is exactly how the OEM joints were installed.
