Most accidents involve the front-end and back-end of the car. With the exception of t-bone accidents, hail damage, and other minor damage that can occur from the parking lot. However, many accidents damage the front and rear bumper cover.
Bumper covers have tabs that break frequently during accidents. In fact, a broken mounting tab may be all that is wrong with the bumper cover. Before deciding to replace the bumper cover, check out this tutorial for repairing broken mounting tabs.
Many times it may require removing the bumper cover to perform the repair, but it is possible to repair the tab without removing the bumper cover. This is going to depend on the individual cover and the location of the damage.
