The standard bolt (19a) is centered by the bumps (arrows) in the bearing of the torque strut or spring link. Grooves in the repair bolt (19c) permit it to be installed in the bearing on either the right or left side, allowing the torque strut or spring link to be adjusted by a distance of 4 mm to the inside or outside.

After installation in the bushing in the torque strut or spring link do not turn the repair bolt (19c). Because the rubber bushing on the radius rod or track control arm should be free to turn when the suspension is compressed, the nut should not yet be tightened.
