Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.
Use wheel chocks to prevent the vehicle from rolling.

2. Remove the Wheels

Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts using a socket set and take off the front or rear wheels.

3. Remove the Strut Assembly

Disconnect any components attached to the strut, such as brake lines or sway bar links.
Unscrew the bolts securing the strut to the wheel hub and the upper strut mount.
Carefully remove the strut assembly from the vehicle.

4. Install New Struts

Compare the new struts with the old ones to ensure proper fit.
Install the new strut into the strut mount and secure it using the appropriate torque specifications (refer to the vehicle's service manual for exact values).
Reattach the sway bar links and brake lines if applicable.

5. Reinstall the Wheels

Place the wheels back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer's specifications.

6. Test Drive

Conduct a test drive to evaluate the performance and ensure that the ride quality has improved.
