If you are replacing front steering tie rods there are times when the pickle fork will just not loosen up the ball joint. I have had some instances where even a two pound hammer can not break the tie rod joint loose. In that case you will need to use this threading lifting tool. If you are planning to reuse the tie rod then you definitely need to use this tool as it will prevent tearing the rubber boot. If you do a lot of your own work or have multiple Mercedes this is a must have special tool. Comes with simple instructions.
