OLD BALL JOINTS
Here is the old style Ball-Joint.  As you can see, there is no grease fitting to fill it.
Here is rubber boot on the old ball-joint.  As you can see it is cracking in the middle.
Another aging Ball-Joint.
Here I have split the Ball-Joint open with a pen, the rubber is already lost it's seal and the inside of the Ball-Joint is dry and rusted.

The above ball-joints are in need of being replaced.
