If the collision was so severe that the bumper did not return to the original position, replace the energy absorbers using the following steps:

1. Stand clear of the bumper.
2. Hold the bumper in the current position with a positive restraint, such as a chain or a cable.
3. Wear safety glasses. Use a 3 mm (1/8 in) drill (3) in order to drill a hole in the piston tube (1) near the bumper bracket. This will relieve the gas pressure.
4. Remove the energy absorbers after you have relieved the gas pressure.
