- Carefully pull the strut assembly out from the vehicle.
Rear Struts:
- Remove the wheel similarly as above.
- Disconnect any sway bar links connected to the strut.
- Remove the bolts securing the bottom of the strut to the axle assembly.
- Remove the top strut mounting bolts accessible from the trunk area.
- Extract the strut from the vehicle.

4. Install New Struts

Position the new strut in place, ensuring it aligns with the mounting points.
Front Struts:
- Insert the strut into the top mount and secure it with bolts.
- Reattach the bottom of the strut to the steering knuckle and tighten the bolts to the manufacturer's torque specifications.
- Reconnect the brake line and clips.
Rear Struts:
- Insert the new strut into the top mount and secure it with bolts.
- Attach the bottom of the strut to the axle assembly and tighten the bolts to specifications.
- Reconnect sway bar links if applicable.

5. Final Assembly

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle to the ground and torque the lug nuts to the manufacturer’s specifications.
Reconnect the battery.
