How to install Grease/Zerk Fittings (Threaded and Drive Type)

You may come across these fittings with your ball joints, tie rods, or other suspension components which require periodic maintenance.
I will be showing you how to install two of the most common fittings in the field.
Threaded fittings are the easiest to install. Just thread them in and tighten them till it's flush with the surface. They're easy for replacement if it gets damaged or plugged.
Drive type requires you to drive it into the cavity. These fittings are harder to remove in the future because they require drilling.

ANGLED FITTINGS require more planning before installation. You want the fitting to be accessible after installation of the component. Do it correctly and you'll thank yourself in the future.
