A hood lifting mechanism according to various implementations includes a housing and a piston. A distal end of the piston is urged away from a distal end of the housing to lift a hood upwardly away from a vehicle body in response to the vehicle hitting a pedestrian. To prevent the piston from rattling or moving within the housing while in a stored position, a portion of the piston and a portion of the housing form an interference fit in the stored position. A gas generator in fluid communication with a proximal end of the housing provides sufficient force to overcome the interference fit and urge the distal end of the piston out of the housing.
