Abstract: An energy absorber of the type having a plurality of rolling bodies engaged between a pair of telescopable cylinders mounts a bumper to a vehicle. One of the telescopable cylinders is attached to the vehicle frame and the other is releasably clamped to the bumper and includes a splined surface on the inner periphery thereof. A restoring tool includes a hook which is used in conjunction with a conventional bumper jack in pulling the bumper away from the frame, thus restoring the cylinders to their pre-impact axial relation. The restoring tool also includes a splined portion which, subsequent to release of the clamp attaching the cylinder to the bumper, is inserted into the cylinder and used in conjunction with the bumper jack to effect rotation of the cylinder and consequent alignment of the rolling bodies with an undeformed area of the cylinder.
