Here are the items you'll need for this repair: T20 Torx socket, ratchet, socket extension, flat blade screwdriver, side cutters, and needle nose pliers

Remove the seven T20 Torx screws. We have two on the bottom here and five running up along the backside of the bumper and the fender. Remove the eight plastic clips securing the inner fender well in. We have three in the top area here, one over at the front (in the middle), two down at the bottom, and these two at the back of the front portion of the liner at the bottom in the middle here.

There's a few different ways to remove these style clips. I like to try to take a small flat blade screwdriver and work up the center part of the clip just a little. Once you get it up some, if you have the room to get in there with a pair of side cutters, you can sneak them underneath and then pry up evenly from both sides. Once the center's out, you can pop the lower portion out the same way.

To remove the wheel liner, pull out on the bottom portion here and pull down and forward to release the front half of the wheel well from the rear and sneak it out of the bottom.

You can do this on the ground if you work the wheel and tilt it so you can reach in and access all the clips and screws, but it's easier to take the wheel off if you want to raise and support your vehicle like we have. Remove this retainer for the wiring harness to the wheel speed sensor, as well as this pushpin at the bottom and the one at the top. Remove the six T20 Torx screws on the backside of the fender well. We use a Torx bit ratchet and extension for that. See, I'm using my left hand to put some pressure against the wheel well here because this last screw is all that's holding it in. Once we get that out, you can remove the rear half of the wheel well liner.

These clips below the fender line simply pop out of the bumper while these six along the rest of the wheel well will need to be popped out very carefully with a pair of needle nose pliers. You can see that you have the two spread tabs on the back of this clip. We want to squeeze those together carefully. They're just plastic. Squeeze them together, and slide them through.

This outer flair can be pretty brittle, so be sure not to force anything or you risk cracking and damaging the trim. Repeat these steps on the opposite side to remove the forward and rearward wheel well, as well as the fender flair on the outside.

Line up the clips on the back of your fender flair with the holes inside of the fender and the bumper. They should snap back into place with just a little bit of pressure.

Reinstall the rear portion of the wheel well liner. I like to start with the push clips because they're the fastest to put in to hold it in place. Get the one on the bottom, one at the top, and the retainer for our ABS sensor, and we'll reinstall the six T20 Torx screws on the back side of the liner.

Reinstall the forward portion of the front inner wheel well liner. In this shop the tire is on but it can be done with the tire on or off the vehicle. Once you have some holes lined up you can start installing your 8 push pins. Set them up like this. Install the bottom half and then pop the tab into place. Reinstall your seven T20 Torx screws. We'll start them a couple of threads by hand before we install them with our socket and ratchet.
