This figure shows two different types of Ball Joints.
FA2026 is an 11mm thread Ball joint. It is smaller in shaft diameter compared with FA1044.
The following pictures show how I installed FA2026 on my '72 wagon. This was not a great set up as I had to tighten it a lot and required a lot of work. I uninstalled it after I realized that I was using the wrong ball joint.
This picture shows a washer installed underneath the nut. This is how the 11mm thread ball joint was installed after it was completely tightened up.
This picture shows the 11mm ball joint being tightened down. A harmonic balancer tool was used to help install the ball joint. Again, this was the wrong ball joint to install on a '72 510 wagon.
This note from the autoparts store shows prices for parts that I need to purchase to upgrade my front suspension system.The correct ball joint for my 510 is the 14mm ball joint.
