Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues while working on the vehicle.
Gather tools: floor jack, jack stands, socket set, torque wrench, strut spring compressor, and a screwdriver.

2. Lift the Vehicle

Use a floor jack to raise the front or rear of the vehicle (depending on which struts are being replaced).
Secure the vehicle with jack stands to ensure stability.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Repeat this for the other side if replacing front and rear struts.

4. Remove the Strut Assembly

Locate the strut mounting bolts at the top and bottom of the strut assembly.
Use a socket set to remove the lower strut bolts (may require holding the bolt head with a wrench).
Remove the upper strut mounting nuts from inside the engine bay or rear trunk area.
Carefully remove the strut assembly from the vehicle.

5. Replace Strut Assembly

Use a strut spring compressor to compress the coil spring on the old strut.
Once compressed, remove the top strut nut and carefully take off the coil spring.
Install the coil spring onto the new strut assembly in the same orientation as it was on the old strut.
Reinstall the top strut nut and ensure it is tightened to the manufacturer's torque specification.

6. Install New Strut Assembly

Position the new strut assembly in place of the old one.
Reinstall the upper strut mounting nuts and torque to specification.
Reattach the lower strut bolts and torque them to specification.

7. Reinstall the Wheel

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the specified value.

8. Final Checks

Reconnect the battery.
Ensure all tools are removed from the vehicle.
