I got to differ with you on this one. Until you experience the difference you won't appreciate this conversion. A day and night difference. All the problematic issues associated with the yerf ball joint system are eliminated such as tracking, holding alignment, camber, along with adding strength and dependability. Ball joints are a traditional method and have proved dependable in countless applications but in this particular instance there is no such creature. I've built over a dozen sets for folks through the years with zero failures. My first set is over 10 years old going strong.
If the bungs are welded in correctly it becomes the strongest link in the system.
The first pic shows the bung in a piece of tube inserted into the end of the drilled A-arm. The second is the finished product. notice the inside of the A-arm is boxed.
