The standard bolt (19a) is centered by humps (arrows) in the rubber mount of the torque strut (18) or spring control arm (17). Due to grooves in the repair bolt (19c) this can be installed in the right or left position in the rubber mount, an adjustment range of the torque strut (18) or of the spring control arm (17) of 4 mm inwards or outwards occurring.

The repair bolt (19c) must not  be twisted after fixing in position in the rubber mount of the torque strut (18) or of the spring link (17). Do not yet tighten nut (19b) to enable the rubber mount on the torque strut (18) or of the spring control arm (17) to rotate when the vehicle is rocked to settle the suspension.
