No it is not first hand for me, but based on several owner testimonials. For the Edge, generally, with a few exceptions, you are better off sticking with Motorcraft/Ford parts rather than aftermarket to retain OEM quality operation. Aftermarket parts either do not fit well, or do not last long. If you can find a Motorcraft branded ball joint, or are willing to do the job again, give it a go. Keep us updated either way
