He nipple on the steer rack is for oil, not grease. I believe the thought is that if you disassemble the rack this is the easiest way to fill it back up. It takes ten ounces of hypoid oilI am rebuilding the steering rack on my 1959 Bugeye. The inner balljoints do not have grease nipples. Do you have to grease them before you assemble? I don't see how the single grease nipple on the rack is
getting grease into these ball joints.
