If you’re doing any serious automotive suspension work, you’re eventually going to find yourself in need of a tie rod/ball joint separator. It’s essentially a big wedged fork that you drive between the ball and socket to disconnect them. You can buy them individually, but the best way to fill this need is to pick up a kit with all the different sizes so you have them on hand. Unfortunately, many of those kits are quite expensive.
This one from Performance Tools seems to hit your wallet the least while still being a complete set. We found it selling for $36.75 at mytoolstore.com. It features 5 different sizes and will separate most types of Pitman Arms, tie rods & ball joints found on automotive and light truck applications.
