Before servicing the left front wheelhouse splash shield, lift and support the vehicle on safety stands, take off the left front wheel and remove the battery splash shield. Then, loosen the screws that connect the wheelhouse splash shield to the fender lip, pop out the fastener that secures the shield to the fender at the rocker and remove the fasteners that connect to the fender's support. Once all these pieces are gone, take out the wheelhouse splash shield from your car. The splash shield fits between the fender support and the fender at the rocker panel; simply push the push-in fasteners into place to install. Screw the metal strips back into the front fender lip, secure the battery splash shield, attach the left wheel to the car and tighten its lug nuts before moving it from the hoist.
