Tools Required: Jack, jack stands, lug wrench.
Lift the front of the vehicle using a jack and secure it with jack stands.
Remove the front wheel by loosening and removing the lug nuts with a lug wrench.

3. Examine Steering and Suspension Components

Visually inspect the steering rack and tie rod ends for any signs of damage or wear.
Check the ball joints and control arms for any play or grinding.
Replace any worn or damaged components found during the inspection.

4. Lubricate Components

If no damaged parts are found, lubricate the steering joints and any moving parts in the suspension system using a high-quality grease.
Ensure that all fittings are filled adequately and wipe away any excess grease.

5. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (generally around 100 ft-lbs for the Model 3).
Reconnect the negative battery terminal.
