Ball joints on steering gear in your vehicle is of the (normally)
latter type.

Pins on heavy equpment..which we are talking about..is of the first
type. Or are you saying that you grease once..and once its
filled..you
never grease again?

Then we have things like automotive drive lines and U joints.
(Grin)..which catagory do those fall into? Hummm?

As I said..this is not..not my first rodeo.

Factory U joints are greased for life.

Their life ends when all the grease is gone.

The "good" ones still come with a plug that can be removed and a zerc
installed. The "****ty" ones are not even cross drilled to allow
grease distribution.

Absolutely correct

One has to be a bit careful about installing zerks in u-joints
though...some will fit properly..others if they are too tall...get
broken off if the joint is flexed widely.

And the same with steering gear parts
