CAUTION:
^ Do not remove the nut from ball joint. Loosen it and use special tool MB991897 to avoid possible damage to ball joint threads.
^ Hang special tool MB991897 with a cord to prevent it from failing.





1. Replace the self-locking nut for lower arm ball joint with a regular nut, because the original one is too large to install the special tool. And then install special tool MB991897 as shown in the figure.





2. Turn the bolt and knob as necessary to make the jaws of special tool MB991897 parallel, tighten the bolt by hand and confirm that the jaws are still parallel.

NOTE: When adjusting the jaws in parallel, make sure the knob is in the position shown in the figure.

3. Tighten the bolt with a wrench to disconnect the ball joint.
