This was a very interesting read for sure! Definitely backs up what many of us have said from time to time regarding box store reman parts - you might have to go thru 2 or 3 to get a good one lol. I try to always purchase the new product over the reman whenever possible from my parts houses and that seems to really improve my odds of getting a good part. I have not had issues with AZ new parts like I have seen on the reman parts. I am sure these remans are made of common parts shared across several lines so they can't be 100 perfect but just enough to get by most of the the time. The rest of the issues come with the skills of the rebuilders which obviously is not always good.
