These GM steering boxes are the recirculating ball type. They use a lighter weight grease than some others such as cam-and-lever. Make sure you sue the specified grease. As I recall cornhead grease comes in several viscosities; the heavier ones not only won't run out of the box through leaking seals, they won't lube the balls in the recirculating mechanism.
