2. Remove the Struts

Lift the Vehicle: Use a jack to lift the vehicle and secure it with jack stands.
Remove the Wheels: Take off the front wheels to gain access to the struts.
Disconnect Components: Remove any components obstructing access to the strut (e.g., sway bar links, brake lines).
Unbolt the Strut: Remove the bolts securing the strut to the steering knuckle and the upper strut mount.
Remove the Strut Assembly: Carefully take out the strut assembly from the vehicle.

3. Inspect and Replace

Inspect the Strut: Examine the strut for signs of wear, damage, or leaking fluid.
Compress the Spring: If replacing, use a strut spring compressor to safely remove the spring from the old strut.
Install New Strut: Attach the spring to the new strut, ensuring it is properly seated.
Reinstall the Strut Assembly: Position the new strut assembly in place and secure it with bolts, following manufacturer torque specifications.

4. Reassemble Vehicle

Reconnect Components: Reattach any components that were removed, such as sway bar links and brake lines.
Reinstall Wheels: Place the wheels back on and hand-tighten the lug nuts.
Lower the Vehicle: Carefully lower the vehicle to the ground and torque the lug nuts to the specified value.
