Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, strut spring compressor, impact wrench (optional), flathead screwdriver, and pry bar.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical issues.

2. Remove the Wheel

Loosen the lug nuts while the vehicle is on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the strut.

3. Remove the Strut Assembly

Top Mount Bolts: Locate and remove the bolts securing the strut to the top mount using a socket set.
Lower Strut Bolts: Remove the lower bolts that attach the strut to the steering knuckle.
Carefully detach any brake line clips or sensors attached to the strut.
Remove the strut assembly from the vehicle.

4. Replace the Strut

Use Strut Spring Compressor: If reusing the spring, place the strut assembly in a spring compressor and compress the spring.
Remove the top nut of the strut assembly to detach the strut from the spring and mount.
Install the new strut into the spring and secure it with the top nut, following the manufacturer's torque specifications (typically around 50 ft-lbs).
Carefully release the spring compressor.

5. Reinstall the Strut Assembly

Position the strut assembly back into its original location.
Reattach the lower strut bolts to the steering knuckle and torque them to the manufacturer's specifications (usually around 80-100 ft-lbs).
Reattach the top mount bolts and torque them appropriately.

6. Reassemble the Wheel

Place the wheel back onto the hub, hand-tighten the lug nuts.
Lower the vehicle to the ground and torque the lug nuts to the manufacturer's specifications (typically 76 ft-lbs).

7. Final Checks

Reconnect the battery.
Inspect for any loose connections or components that may have been overlooked.
