Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Socket set
- Torque wrench
- Spring compressor
- Strut nut socket
Sub-steps:
1. Park the vehicle on a flat, level surface and engage the parking brake.
2. Disconnect the battery to eliminate electrical hazards.
3. Loosen the lug nuts on the front wheels while the vehicle is on the ground but do not remove them yet.

2. Lift the Vehicle

Sub-steps:
1. Use the jack to lift the front of the vehicle and secure it with jack stands.
2. Remove the front wheels by fully unscrewing the lug nuts.

3. Remove Strut Assembly

Sub-steps:
1. Locate the strut assembly and remove the two lower strut bolts using a socket wrench.
2. Remove the upper strut mount bolts from the engine compartment, ensuring to support the strut while doing this.
3. Carefully detach the strut assembly from the vehicle, ensuring not to damage surrounding components.

4. Replace Strut

Sub-steps:
1. Using a spring compressor, compress the coil spring on the old strut assembly to prevent injury.
2. Remove the strut nut at the top of the assembly and carefully take off the spring and mount.
3. Install the spring onto the new strut assembly, tightening the strut nut to the manufacturer's specifications (usually around 30-35 ft-lbs).
4. Release the spring compressor slowly after ensuring everything is securely in place.

5. Reinstall Strut Assembly

Sub-steps:
1. Position the new strut assembly into place and secure it by reinstalling the upper mount bolts.
2. Attach the lower strut bolts and torque them to the specified value (typically around 85-100 ft-lbs).
3. Reinstall the front wheels and torque the lug nuts to the manufacturer's specifications (usually 150-160 ft-lbs).

6. Final Checks

Sub-steps:
1. Remove the jack stands and lower the vehicle back to the ground.
2. Reconnect the battery.
3. Perform a brief test drive to ensure proper operation and check for any unusual noises.
