Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Wear safety glasses and gloves for protection.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the front wheels using a lug wrench.

3. Remove the Strut Assembly

Tools Required: Socket set, torque wrench, impact wrench (if necessary).
Remove the lower strut mounting bolts using a socket wrench.
Disconnect the sway bar link from the strut if applicable.
Remove the upper strut mount nuts from the engine bay (may require removing other components for access).
Carefully lower the strut assembly from the vehicle.

4. Inspect and Replace the Strut

Check the strut for any visible damage or wear. If leaking, replacement is necessary.
Install the new strut into the strut assembly.
Torque the upper strut mount nuts to the manufacturer's specifications (usually between 20-30 lb-ft, consult the service manual for exact torque values).
Reconnect the sway bar link if it was removed.

5. Reinstall the Strut Assembly

Position the strut assembly back into the vehicle.
Secure the lower strut mounting bolts and torque to the specified value (typically around 85 lb-ft).
Reinstall the front wheels and lower the vehicle back to the ground.

6. Final Checks

Ensure all bolts are tightened to specifications.
Recheck fluid levels in the system if necessary.
