2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Ensure all safety measures are in place before working underneath the vehicle.

3. Inspect and Replace Suspension Components

Shock Absorbers/Struts:
- Remove the wheel to access the shock/strut assembly.
- Disconnect the top and bottom mounting bolts using a socket set.
- Remove the shock absorber/strut from the vehicle.
- Install the new shock absorber/strut, ensuring to torque the bolts to manufacturer specifications.
Sway Bar Links:
- Locate the sway bar links and remove the nuts using a wrench.
- Inspect for wear; if damaged, replace with new sway bar links.
- Reinstall the new links and secure with nuts, torquing to specifications.
Bushings:
- Remove any components obstructing access to the bushings.
- Use a bushing removal tool to remove worn bushings.
- Press in new bushings and reassemble components.

4. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the recommended specifications.
