NECTION

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 falling.

1. Replace the self-locking nut for lower arm ball joint with a

regular nut, because the original one is a little bit 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.
