You’ll notice that once the upper ball joints are pressed into these arms there is what’s best called a “pocket” left behind where the upper ball joint grease fitting is located.
I really don’t like the idea of water and mud collecting around the upper control arm grease / zerk fittings… the pocket at the upper ball joint cup is not sealed from the elements nor is there a hole drilled to permit water and light dirt to drain away.
So, I installed these black plastic/nylon end caps into the grease fitting pockets on both of my AllDogs high clearance upper control arms to keep water and dirt away from the grease fittings, and to clean up the look of these awesome upper control arms.
Go to Amazon,, look for these…
2-1/4" Round Plugs (10-14 Ga 1.99" to 2.08" ID) || 2.25 Inch OD Black Plastic End Caps
Once you get them, use a utility knife to carefully trim away the very first ring at the base on the plug, this will allow the plug to drop into place in proper alignment to allow the plug to be pressed In until the cap is flush with the upper rim of the pocket.
Enjoy the peace of mind knowing there isn’t a pool of water and mud wreaking havoc on your upper ball joints and grease fittings..
