Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical issues, especially if equipped with active suspension components.

2. Raise the Vehicle

Tools Required: Jack, jack stands, wheel chocks
Use a jack to raise the vehicle and secure it on jack stands.
Remove the front or rear wheel (depending on which strut is being serviced).

3. Remove the Strut Assembly

Tools Required: Socket set, torque wrench
Disconnect the sway bar link from the strut (if applicable).
Remove the bolts securing the strut to the knuckle.
Remove the upper strut mount bolts from the engine compartment or under the dashboard.
Carefully remove the strut assembly from the vehicle.

4. Inspect and Replace Components

Check for any visible damage to the strut, mount, and bushings.
If any component shows wear (e.g., torn rubber, leaking fluid), replace it accordingly.
Install new strut mounts and bushings if needed.

5. Reinstall the Strut Assembly

Position the new or inspected strut into place.
Secure the strut to the knuckle and upper mount with the appropriate torque specifications (refer to the service manual for exact torque values).
Reattach the sway bar link.

6. Reassemble and Lower the Vehicle

Reinstall the wheel and lower the vehicle.
Reconnect the battery.
