Review on Top-Quality Beck Arnley 101-5042 Lower Ball Joint: Superior Performance and Durability by Matthew Perez

When they arrived a careful inspection revealed that the stud and nut were not round and could not be screwed on. There is a notch at the end of the threaded bolt that allows you to insert a hex wrench to hold the bolt while you tighten the nut. This hexagonal indentation was off-center and distorted. It actually looked like the recess with the nut had been "knocked out" and the nut wasn't round. Returned them for a full refund. I've read online that Beck Arnley is essentially a "repacker" not a manufacturer and that items with the same part number can be sourced from many manufacturers that vary wildly in quality. I don't know if that's true, but mine were junk and a huge waste of time and money, especially since I had to source parts locally to keep up with my schedule. The parts bought locally were much more expensive than identical parts I could buy online.
