⚠️ Safety & Precautions

• Use jack stands on solid ground. Never work under a vehicle held up only by a jack.
• The spring is under high tension. Replace the complete strut assembly if possible. Do not disassemble the spring without a spring compressor.
• Support the steering knuckle so brake hose and CV axle are not stretched.
• Mark camber bolt positions before removal if your front bolts have alignment cams.
• An alignment is required after this repair.

Step 2: Free the strut from the steering knuckle

• Use a 17mm socket and 17mm wrench to remove the lower strut bolts and nuts.
• Mark the bolt positions with a paint marker before removal if camber bolts are fitted.
• Support the knuckle with a bungee cord or hanger so the brake hose is not pulled tight.

Step 3: Disconnect the stabilizer link and brackets

• Use a 14mm wrench or 14mm socket to remove the stabilizer link nut from the strut.
• Remove any brake hose or wire brackets attached to the strut with a 14mm socket.

Step 4: Remove the upper strut mounts

• Open the hood and locate the three upper strut mount nuts.
• Use a 14mm socket to remove the upper nuts while holding the strut assembly from below.
• Lower the old strut assembly out of the wheel well.

Step 5: Install the new strut assembly

• Align the lower holes with the knuckle and install the lower bolts and nuts using a 17mm socket and 17mm wrench.
• Torque the upper strut mount nuts to 39 Nm (29 ft-lbs).

Step 6: Reconnect the lower hardware

• Reconnect the stabilizer link using a 14mm wrench.
• Reinstall brake hose and wire brackets with a 14mm socket.
• Torque the lower strut-to-knuckle fasteners to 177 Nm (131 ft-lbs).
• Torque the stabilizer link nut to 44 Nm (32 ft-lbs).

Step 7: Reinstall the wheel and repeat
