Unscrew nut from cross strut mounting on front axle carrier (4) and remove bolt from front axle carrier (4)


Always counterhold bolt when releasing the nut to ensure that the bolt does not turn too.
Otherwise, on cross struts with an installed repair kit, the lock tabs for the camber adjustment in the elastomer bearing may be sheared off.

 Installation: Tighten nut of bolt far enough so that the elastomer bearing can still turn when rocking vehicle to settle suspension. Do not tighten nut until in the ready to drive condition.
