That's been going on for a ling time. I went to Auto Zone and bought a pack of assorted zerks, drilled and installed on everything that did not have one on my 99.17 3500 4X4 Am I missing something, or is it you can't lube the ball joints?
Sad part is nothing is maint. free, Wife,kids,vehicle and on and on.Greasing went by the wayside many many years ago in the automotive industry. Everything now is sealed maintenance free.
Like said above, if your truck is 4wd, the front driveshaft gets greased at every oil change. Should be a sticker under the hood.
