Do not use an air or electric impact wrench to tighten the upper mounting nut on the piston rod. This can make the torque higher than recommended and cause damage. Correct tightening is accomplished by holding the piston rod with a wrench or special tool (not vice grips or pliers) at the machined shoulder & using a torque wrench set to the vehicle manufacturer’s specification.
