The part seems to be well made. However after installing it I started filling it with grease and the metal ring covering the rubber boot came off and the grease went everywhere. I had to disassemble the ball joint to remove all of the grease and bought a smaller o-ring that could hold the grease. It works fine now that I've modified it, but it's very frustrating to spend so much time installing a part only to then remove it, spend more money, and then reinstall it.
