📋 Before You Begin

• Park on a flat surface, shift to Park, and set the parking brake.
• Place wheel chocks behind the rear wheels.
• Turn the steering wheel fully away from the side you’re working on (gives more hand room at the fender liner).
• Tip: Replacing both sides saves time later.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the front wheel lug nuts (optional but recommended)

• Use a 21mm socket with a 1/2" drive breaker bar to loosen the lug nuts about 1/2 turn while the wheel is still on the ground.

Step 2: Lift and support the front corner

• Lift the front corner with a floor jack (rated 2-ton minimum).
• Set the vehicle onto jack stands (rated 2-ton minimum).
• Keep the floor jack lightly touching as a backup if possible.

Step 3: Remove the front wheel

• Remove the lug nuts using the 21mm socket and 3/8" drive ratchet (or breaker bar), then remove the wheel.
• Set the wheel flat under the vehicle as an extra safety backup.

Step 4: Open the front fender liner for access

• Use a trim clip removal tool to pop out the plastic push-clips along the front section of the fender liner (splash shield).
• Remove any screws in that same area using a Phillips screwdriver #2.
• If a small bolt is present, remove it using a 10mm socket, 3/8" drive ratchet, and 6" socket extension.
• Gently pull the liner back just enough to reach the back of the headlight.
• Trim clip tool = pry tool for plastic fasteners.

Step 5: Remove the turn signal bulb socket

• Use a flashlight to locate the turn signal bulb socket on the back of the headlight housing.
• Grip the socket and rotate it counterclockwise by hand until it unlocks, then pull it straight out.

Step 6: Replace the bulb

• Wear nitrile gloves.
• Pull the old bulb straight out of the socket (it’s a wedge-fit bulb).
• Push the new front turn signal bulb (amber, 7440A/7440NA type) straight into the socket until fully seated.
• Don’t touch bulb glass with bare hands.

Step 7: Reinstall the socket and test

• Insert the socket back into the headlight and twist clockwise by hand until it locks.
• Turn the ignition ON and test the turn signal and hazards for that side.
• If it doesn’t light, turn ignition OFF, remove the socket again, and reseat the bulb firmly.

Step 8: Reinstall the fender liner and wheel

• Reposition the liner and reinstall all clips using the trim clip removal tool (push them back in).
• Reinstall screws with a Phillips screwdriver #2.
• If removed, reinstall the bolt using a 10mm socket and 3/8" drive ratchet.
• Put the wheel back on and hand-thread the lug nuts.
• Lower the vehicle off the jack stands using the floor jack.
• Tighten lug nuts in a star pattern using a 1/2" drive torque wrench: Torque to 133 Nm (98 ft-lbs).

Step 9: Repeat on the other side

• Repeat Steps 1-8 for the opposite front turn signal.

✅ After Repair

• Test left and right turn signals, hazards, and parking lights.
