Take note of the following statements:
| • | Do not try to repair a damaged energy absorber. | 
| • | Replace the energy absorber if damaged. | 
| • | Do not apply heat to the energy absorbers. | 
| • | Do not weld the energy absorbers. | 
Look at the following components for signs of visible distortion:
| • | Look at the bumper impact bar bracket. | 
| • | Look at the piston tube. Scuffing of the piston tube occurs when it is stroked and this is considered to be normal. | 
| • | Look at the frame bracket. | 
| • | Look at the cylinder tube. | 
Replace the energy absorber if obvious damage is evident. Replace the energy absorber if a collision is so severe that the bumper impact bar does not return to its original position.
