This is concerning my 2002 Ram 1500 2wd. I am sure it did not come from the factory with greasable u joints so I will assume that they were changed at some point. The ones on there are greasable but I cannot access them. I can see them but the fitting on my gun is straight and too tall. It hits the yoke before it locks onto the zerk. Anyone else run inot this. Any fittings that might make greasing these SOBs possible, or should I just run them till they need changing?
