<> SELF LOCKING NUT (CONNECTION FOR
LOWER ARM BALL JOINT AND TIE ROD END)
REMOVAL
Do not remove the nut from ball joint. Loosen it and use
the special tool to avoid possible damage to ball joint
threads.
Hang the special tool with cord to prevent it from fall-
ing.
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. Install special tool MB991897 as
shown in the figure.
2. Turn the bolt and knob as necessary to make the jaws of
special tool 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 lower arm
ball joint, tie rod end and remove the self locking nut.
