Q: How to remove and install bumpers on Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?
A: Bumpers on trucks are usually chrome-plated steel with black or color-matched plastic grilles, but flexible plastic covers reinforced by metal framework can be seen on SUVs. To remove the front bumper, it is necessary to jack it up and unplug electrical connectors of fog lights, then remove fasteners for radiator grille and fender liner before removing the bumper along with an assistant holding it. For rear bumpers, lift them using a jack or stand, unplug plugs for license plate lamps and other components from which bolts, nuts as well as stud plates need to be removed that hold this part to the frame. For SUV models' front bumper cover removal: headlights housings out, fender liner fasteners out; electrical connectors at the fog lights undone; top of each fender well unclip together inside at the bottom of each side; fasteners above grill that attaches cover on top of radiator support undone. The rear bumper cover should have its rear fender liners removed, lower screws at their bottoms off; top ones as well as those placed inside both sides detached; fasteners from atop undone including electrical connectors for back parking sensors being taken apart. In order to install any bumpers follow these steps in reverse.
