🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the front wheel lug nuts

• Use a 19mm socket and 1/2" drive breaker bar to loosen the lug nuts about 1/2 turn while the tire is still on the ground.

Step 2: Raise and support the front corner

• Use a floor jack (rated 2-ton minimum) to lift the front corner you’re working on.
• Set the car onto a jack stands (rated 2-ton minimum).
• Shake the car gently to confirm stability.

Step 3: Remove the front wheel

• Remove the lug nuts using the 19mm socket, then remove the wheel.

Step 4: Open the front wheel-well liner access

• Use a 7mm socket and 1/4" drive ratchet to remove the small screws along the front edge of the wheel-well liner (near the bumper/headlamp area).
• Remove plastic push-clips using the trim clip removal tool. If needed, gently help the center pin up with a flathead screwdriver, then pull the clip out.
• Pull the liner back just enough to reach behind the headlamp. Use a work light so you can clearly see the bulb sockets.

Step 5: Remove the turn signal bulb socket

• Find the turn signal/park bulb socket at the rear of the headlamp (it will twist-lock into the housing).
• Grip the socket and rotate it counterclockwise about 1/4 turn, then pull it straight out.
• If it’s tight, wiggle—don’t yank the wires.

Step 6: Replace the bulb

• Wear nitrile gloves and pull the old bulb straight out of the socket.
• Push the new bulb straight in until fully seated.
• Use a work light to confirm the bulb is sitting square (not crooked).

Step 7: Reinstall the bulb socket

• Insert the socket back into the headlamp and rotate clockwise until it stops (locked).
• Tuck the wiring so it won’t rub on the tire or get pinched by the liner.

Step 8: Reinstall the wheel-well liner fasteners

• Reposition the liner and reinstall the push-clips by hand.
• Reinstall screws using a 7mm socket and 1/4" drive ratchet until snug.

Step 9: Reinstall the wheel and torque lug nuts

• Reinstall the wheel and hand-thread lug nuts.
• Lower the car off the jack stand using the floor jack (rated 2-ton minimum).
• Use a 1/2" drive torque wrench with a 19mm socket and tighten lug nuts in a star pattern: Torque to 135 Nm (100 ft-lbs).
