REMOVAL & INSTALLATION
140, 160 and 1800 Series
Both the front and rear bumpers of these cars are composed of various sections bolted together. The bumpers are mounted to the car on four support brackets (1800 ES: six brackets). The retaining nuts and bolts are loosened and removed; the bumper may then be removed from the car as a unit and disassembled into component parts on the workbench.
The retaining bolts are reached from under the car (behind the bumper). It may be easier to elevate and support the car before beginning. The bumper bolts are sure to be rusted solid-have a healthy supply of penetrating oil at hand. The steel bumpers are reasonably heavy-don't drop one on yourself while lying under the car.
When reinstalling the bumper, make sure that it aligns properly with the bodywork. Since it runs the full width of the car, the slightest mounting error can make it look crooked.200 and 700 Series

As government regulations tightened in the early and mid 1970s, bumpers were redesigned to include impact absorption. This is generally accomplished through the use of gas-filled shock absorbers which allow the bumper to move inward under light impact. The design of the bumpers changed to accommodate the shocks; bumpers are now steel or aluminum beams bolted to the shocks with a plastic cover on the outside. For both front and rear bumpers on cars built after model year 1974:
- Loosen the sides of the bumper cover by either removing the nuts or releasing the plastic clip. The nuts will be found inside the trunk or on the inside of the front fender. On certain models, the front air dam (spoiler) must be removed before removing the front bumper.
- Under the car, identify the bolts which hold the bumper assembly to the shock absorbers. Loosen them a few turns and wiggle the bumper outwards, checking that it will come free without damage.
- Remove the bolts on one side. Either allow the bumper to rest on the ground or support it on a box until the other side is free.
- Remove the bolts on the other side and remove the bumper. Take note of any spacers which may have been placed for alignment.
- With the bumper removed, the shocks may be unbolted and replaced if needed.
- When reinstalling, make sure the bumper lines up straight to the body work. Install the retaining bolts and tighten them.
- Secure the side mounts of the bumper cover with the proper nuts or clips. Install the air dam if it was removed.
