 Ball joint remover, 28 mm 07MAC-SL0A202
Always use a ball joint remover to disconnect a ball
joint. Do not strike the housing or any other part of
the ball joint connection to disconnect it.
1. Install a hex nut (A) or the ball joint thread protector onto the threads of the ball joint (B).
NOTE: Using a hex nut, make sure the nut is flush
with the ball joint pin end to prevent damage to the
threaded end of the ball joint pin.
2. Apply grease to the ball joint remover on the areas shown (A). This will ease the installation of the tool,
and prevent damage to the pressure bolt (B)
threads. 3. Loosen the pressure bolt (A), and install the ball
joint remover as shown. Insert the jaws carefully,
making sure not to damage the ball joint boot.
Adjust the jaw spacing by turning the adjusting bolt
(B).
NOTE: Fasten the safety chain (C) securely to a
suspension arm or the subframe (D). Do not fasten
it to a brake line or wire harness.
4. After adjusting the adjusting bolt, make sure the head of the adjusting bolt is in the position shown
to allow the jaw (E) to pivot.
5. With a wrench, tighten the pressure bolt until the ball joint pin pops loose from the ball joint
connecting hole. If necessary, apply penetrating
type lubricant to loosen the ball joint pin.
NOTE: Do not use pneumatic or electric tools on
the pressure bolt.
6. Remove the ball joint remover, then remove the nut from the end of the ball joint pin, and pull the
ball joint out of the ball joint connecting hole.
Inspect the ball joint boot, and replace it if
damaged.
