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.
