Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, wrench set, torque wrench, strut spring compressor, safety goggles, gloves.
Raise the vehicle using a jack and secure it on jack stands. Ensure it is stable before proceeding.
Disconnect the battery to prevent any electrical issues.

2. Remove the Strut Assembly

Remove the wheel to access the strut assembly.
Detach the brake line bracket from the strut using a socket.
Unbolt the sway bar link from the strut.
Remove the upper strut mount bolts located in the engine compartment (may require removal of interior components for access).
Lower the vehicle slightly to relieve tension and then remove the lower strut bolts from the control arm.

3. Replace the Strut

Using a strut spring compressor, compress the spring on the old strut.
Remove the top strut nut and separate the strut from the spring.
Install the spring onto the new strut, ensuring it is seated correctly.
Reattach the top strut nut and tighten to manufacturer specifications.

4. Reinstall the Strut Assembly

Position the new strut assembly back into the vehicle.
Secure the lower strut bolts to the control arm.
Reattach the sway bar link to the strut.
