My boss has an '03 Super duty 4x4. just a lifted street truck. Greasing the upper ball joints is an hour long affair. Is there a better idea? Samething with the Dodge. Except, it's the lower ones. ( Same Axel, only turned upside down?) This truck only sees the dirt, and mud from the road. However, I don't think a standard 90 degree zerk fitting is going to last until it gets outside the door.
