Easy to replace part on my Durango. I don't see anywhere that it was a used conversion. I thought I had a new part. The box was damaged and oil leaked out. After the part was installed and the oil was topped off, I asked the pros to do a flush. When I was done I was told the part was bad and to get a new one. This used part is loud! Creaks and squeaks when used. I am very disappointed in this purchase and I encourage you to keep looking.
