I have used Lubriplate 1200-2 for 45 or 50 years and never had A problem. I would repack the steering knuckle every 10,000 miles . Never have greased the knuckle in between repacks. Bill at Bill's Jeep in Denver Colorado was trained At Willys Overland in Toledo Ohio and this is the method He used also . He would cut off the square nut on the plugs on the knuckle so they couldn't be lubed between repacks.
