curious if anyone had done this successfully. Reason being is that im working on my work van right now, and to my complete shock, realized it still has the factory GM riveted in ball joints even after 200k miles, and the last 60k in my ownership, particularly punishing as far as pot holes and starts and stops.

Things are tight as a drum, which I largely attribute to being able to grease them through fittings, and it being done regularly. Has anyone installed grease fittings on the MB sealed ball joints? id like to add that feature to my MB as well.
