Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel using a lug wrench.

3. Remove Strut Assembly

Locate the strut mounting bolts on the top of the strut tower and remove them using a socket set.
Remove the lower strut bolts connecting the strut to the steering knuckle.
Carefully extract the strut assembly from the vehicle, making sure to maneuver it free from the brake lines and other components.

4. Inspect and Replace

Inspect the strut for any cracks or damage.
If the strut is leaking, replace it with a new strut specific to the Tesla Model 3 Highland.
Install the new strut in reverse order of removal, tightening the upper and lower bolts to the manufacturer’s specified torque values (usually around 50-70 ft-lbs for lower bolts, check service manual for specifics).

5. Reassemble Vehicle

Reinstall the wheel and tighten the lug nuts in a star pattern to ensure even pressure.
Lower the vehicle back to the ground and recheck the lug nut torque.
Reconnect the battery.
