Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and inspect the fluid level; top off with the recommended fluid if low.
If the fluid appears dirty or contaminated, proceed to the next step.

3. Replace Power Steering Fluid

Use a turkey baster or fluid extractor to remove old fluid from the reservoir.
Refill the reservoir with new power steering fluid according to Tesla specifications.
Start the vehicle and turn the steering wheel to circulate the new fluid, then check the level again and top off as needed.

4. Inspect and Replace Power Steering Pump (if necessary)

If the fluid level is fine but the issue persists, locate the power steering pump.
Disconnect the hoses from the pump using a socket set.
Remove the pump from its mounting position and replace it with a new unit, ensuring all fittings are tight.
Reconnect the hoses and refill the power steering fluid as described in the previous step.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and test the steering feel by turning the wheel left and right at low and high speeds.
Ensure the steering operates smoothly without stiffness.
