On occasion someone will hit something lightly and the bumper will go in, because the supports compress and not come back out. Recently I had this situation on my sisters car. In the past I have suggested that the only was was to remove the bumper but found an easy way.
Here is what you will need to push the bumper back out.
How to push the bumper back out:
Jack up the car and remove the wheel.
Then remove the small piece of inner fender attached to the end of the bumper cover and insert a steel bar about 30 inches long into the opening.
This bar fit nicely into the back side of the aluminum bumper.
I then took a piece of wood to support the end out near the wheel and then hit the end of the rod with a large hammer and the bumper went right back out. Three quarters of the way on the first hit and the second right back to where is should be. I was amazed how easy it was.
If a person does not have a steel bar I am sure a wood 2X2 would also work as it doesn't take much of a hit to get the bumper supports to go back to the original position.
On the rear, in the past I have made a hook and slid it between the bumper and the filler panel and pulled the bumper back out but this method might also work in the rear by simply removing the inner panel.
Thanks to Jim Finn for this information.
