Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, torque wrench, strut spring compressor, screwdriver set.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues.

2. Remove the Wheel

Loosen the lug nuts using a socket.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the strut assembly.

3. Remove the Strut Assembly

Disconnect any brake lines or sensors attached to the strut.
Remove the bolts securing the strut to the knuckle (usually at the bottom).
Remove the upper strut mount bolts located under the hood.
Carefully extract the strut assembly from the vehicle.

4. Replace the Strut

Compress the spring using a strut spring compressor to safely remove the spring from the strut assembly.
Install the new strut in place of the old one, ensuring proper alignment.
Reattach the spring to the new strut, ensuring all components are secured correctly.

5. Reinstall the Strut Assembly

Position the strut assembly back into the vehicle.
Tighten the upper strut mount bolts to the manufacturer's specified torque (typically around 40-50 ft-lbs).
Secure the strut to the knuckle with the lower bolts and torque them as specified (usually around 70-80 ft-lbs).

6. Reattach Components and Wheel

Reconnect any brake lines or sensors that were detached.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern to the manufacturer’s specifications (typically around 76 ft-lbs).

7. Final Checks

Reconnect the battery.
Inspect the installation for any loose components or leaks.
