💡 Why do rear hatch lift struts lose pushing power over several driving seasons? Swapping out tired gas shock cylinders proves handy when tailgate doors start dipping low. - Aging internal diaphragms drain nitrogen gas reducing extension torque gradually - Metal fatigue around pivot eyes increases friction during heavy load cycling - Clean bracket surfaces paired with fresh actuators eliminate stubborn sagging behavior - Matched diameter shafts guarantee smooth sliding motion across wide temperature ranges
