This tool will save your day if you ever get a newer RAM 4500 or 5500 series truck in your bay for ball joints. The way the axle is setup you cannot run the forcing screw through the hole for the upper ball joint and on top of that the angle that the ball joint is pressed in is very inconvenient. We were able to stack adapters on the other side to just barely get the ball joint started and then installed but I found another shop in town that had the tool I needed and that tool is the Snap-on BJP1RAM1 adaptor for the BJP1 ball joint press.
