Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Remove Wheel Assembly

Using a jack, lift the vehicle and secure it on jack stands.
Remove the wheel nuts with a socket wrench and take off the wheel.

3. Remove Strut Assembly

Locate the upper strut mount bolts under the hood and remove them using a ratchet and socket.
Unbolt the lower strut mounting bolts using the appropriate socket.
Carefully detach the strut assembly from the vehicle, noting the orientation for reinstallation.

4. Install New Struts

Position the new strut assembly in place and secure it to the lower control arm with the lower mounting bolts. Torque to manufacturer specifications (typically around 50-70 lb-ft, check specific values).
Attach the upper strut mount and secure with the bolts. Torque to manufacturer specifications.
Reattach any components removed during strut removal, ensuring no loose parts remain.

5. Reinstall Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the nuts.
Lower the vehicle back to the ground and fully tighten the wheel nuts to the specified torque (usually around 80-100 lb-ft).

6. Final Checks

Reconnect the battery.
Perform a test drive to ensure proper function and handling.
