I will not use the upper ball joint. I asked a question if it is possible to lubricate the top with the axle installed. The seller said yes so I ordered this kit for my 1984 Jeep CJ7. I am including a picture of the top ball joint grease fitting hole as it is on the underside and should not be greased during installation. It comes with a grease fitting (you install it, lubricate it, and remove it), then install a plug before inserting the axle. I'm going to buy a Moog Top Pivot.
