Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove the Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Loosen and remove the lug nuts using a socket wrench.
Take off the wheel to access the strut assembly.

3. Disconnect the Strut

Remove any clips or bolts securing the brake line to the strut.
Detach the sway bar link from the strut using a wrench.
Unbolt the strut from the lower control arm using a socket set, and then remove the top mounting bolts from the strut tower in the engine bay.

4. Install New Strut

Position the new strut in place and secure it to the lower control arm with the bolts.
Tighten to the manufacturer's specifications (typically around 50-60 ft-lbs, but verify with a service manual).
Reattach the sway bar link and the brake line clips to the new strut.

5. Reassemble

Reinstall the top mounting bolts in the strut tower and tighten to the manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground, then torque the lug nuts to the recommended value (typically 80-100 ft-lbs).

6. Final Checks

Inspect the area for any signs of leakage after installation.
Test the vehicle for proper handling and ride quality.
