This is the best tool to use when removing throttle linkage ball socket ends on older Mercedes gas and diesel engines. If you try to "twist" them off you can damage the spring clip. It is much better to pry them off evenly. These tools were received from the manufacturer with machine stamping flaws in the head. They still work great but if you are a perfectionist you may not like how they look. :-). Tool only. No supplies or instructions included. Limited stock and price accordingly. Not returnable.
