Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.
Disconnect the battery to ensure no electrical issues while working.

2. Remove the Wheel

Use a lug wrench to loosen the wheel lug nuts while the vehicle is still on the ground.
Lift the vehicle using a hydraulic jack and secure it with jack stands.
Remove the wheel to access the strut assembly.

3. Detach the Strut Assembly

Locate and remove the bolt securing the lower strut mount using a socket set (typically 18-22mm).
Remove nuts from the upper strut mount (typically 13-15mm) located in the engine compartment or trunk, depending on the configuration.
Carefully lower the strut assembly from the vehicle.

4. Inspect and Replace

Inspect the strut for damage. If leaking, it needs replacement.
Remove the strut from the spring using a spring compressor. Ensure the spring is securely compressed before removal.
Install the new strut into the spring and ensure it is properly seated.
Reinstall the strut assembly into the vehicle, reverse the removal steps, and tighten all bolts to the manufacturer’s torque specifications (consult service manual for exact values).

5. Reassemble

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and fully tighten the lug nuts in a crisscross pattern to the specified torque.
Reconnect the battery.
