Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and set the parking brake.
Use wheel chocks to prevent any movement.

2. Remove the Wheel

Sub-steps:
1. Loosen the lug nuts on the wheel using a socket wrench.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Remove the Strut Assembly

Tools Required: Socket set, wrench set, spring compressor.
Sub-steps:
1. Disconnect the brake line and any sensors attached to the strut assembly.
2. Remove the bolts securing the strut to the steering knuckle and upper strut mount.
3. Use a spring compressor to safely compress the coil spring.
4. Remove the top nut from the strut mount to release the strut assembly.

4. Install New Struts

Tools Required: Same as above.
Sub-steps:
1. Position the new strut assembly in place and secure it with the top nut to the strut mount.
2. Reattach the strut to the steering knuckle using the previously removed bolts.
3. Reconnect the brake line and any sensors.
4. Ensure all fasteners are torqued to the manufacturer's specifications.

5. Reassemble

Reinstall the wheel and lower the vehicle.
Tools Required: Same as above.
Sub-steps:
1. Place the wheel back on and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
