Removal Procedure
Caution: Failure to observe the following procedure when handling energy absorbers
could cause personal injury.
| • | Do not apply heat to an energy absorber. |
| • | Do not weld in the area of an energy absorber. |
| • | Do not attempt to repair a damaged energy absorber. Always replace
the damaged energy absorber with a new part. |
| • | If an energy absorber is bound-up as a result of a collision such
that it cannot extend, take precautions to avoid spring-back when bending
sheet metal. Provide a positive restraint, such as a chain or cable to hold
the bumper in the position it is in. Wear approved safety glasses and using
a 3mm (1/8 inch) drill bit, drill a small hole in the piston tube near the
bumper bracket to relieve gas pressure. Remove the energy absorber after
gas pressure has been relieved. |
| • | If an energy absorber is to be scrapped, relieve the gas pressure
prior to disposal of the part. Make an indentation with a center punch in
the small cylinder section of the energy absorber. |
- Remove the rear impact bar. Refer to
Rear Bumper Impact Bar Replacement
.
- Disengage the exhaust system (4) from the exhaust hangers (3) on the rear energy absorbers.
- Remove the fasteners (2, 3) securing the energy absorber assembly (1) to the body.
- Pull rearward to remove the energy absorber (1).
Installation Procedure
- Install the energy absorber (1) to the body.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the 3 nuts (2).
Tighten
Tighten the nuts to 25 N·m (18 lb ft).
- Install the bolt (3).
