2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the front wheels to access the suspension components.
4. Unbolt the top and bottom of the shock absorber/strut using the socket set.
5. Remove the shock absorber and replace it with a new one.
6. Torque the bolts to the manufacturer's specifications (refer to the service manual).
