Another tapered spacer is put into place before the nut is installed. Then reinstall the upper strut retaining nut and washer (if used) and torque to the strut manufacturer's recommended value. If using stock Ford, Koni, or Tokico struts (twin-tube), torque to 45 lb-ft. For Bilstein, Edelbrock, or H&R struts (inverted mono-tube), torque to 54 lb-ft. If a spring compressor was used, slowly release spring tension and remove the compressor from the strut. While loosening the compressor, be sure that both spring pigtails are properly located in both the lower spring perch and on the upper rubber isolator. The strut and spring assembly with the caster/camber plate in place is now ready to be reinstalled into the car.
