Materials Needed

  • Replacement tail light assembly
  • Ratchet with 8mm and 10mm socket and extension
  • Flat head screwdriver
  • Phillips screwdriver

Step 1 – Pull back the trunk lining

Unscrew the cargo net hooks on the side of the trunk. On the sides of the trunk opening there should be another clip you can pry loose. Pull up the black plastic trim in the back of the trunk. Then pull back the side trunk lining to uncover the back of the tail light assembly.

Step 2 – Remove the rear bumper

Pry off the round plastic clips on the bottom of the bumper. These can be pried with a flat head screwdriver. Next you'll need to disconnect the mud flaps from the bumper. These are held by three screws along where the mud flaps and bumper intersect. Return to the top of the bumper and locate the two covers right below the trunk lid frame. Remove the covers and then remove the 10mm bolts underneath. Then, inside the trunk there should be another pair of bolts on either side. Once all the screws, bolts and clips are removed, lower the bumper from the vehicle and move it aside.
