The standard bolt is centered by bumps (arrows) in the front axle carrier. Grooves in the repair bolt (19c) allow the bolt to be installed in the front axle carrier on either the right or left side, thereby allowing the strut rod or cross strut to be adjusted to the inside or outside.

The repair bolt (19c) must not be turned after it has been fixed in place in the front axle carrier. Do not tighten the nut yet so that the rubber mount of the strut rod and cross strut can turn when the vehicle is rocked to settle the suspension.
