Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative terminal of the battery to prevent any electrical issues.

2. Remove the Steering Rack

Tools Required: Socket set, torque wrench, ratchet, and screwdrivers.
Remove the front wheels for better access.
Unbolt and remove any splash shields or covers obstructing access to the steering rack.
Disconnect the tie rod ends from the steering rack using a ball joint separator.
Disconnect power steering lines from the steering rack, ensuring fluid drainage into a container.
Unbolt the steering rack from its mounting points and carefully remove it from the vehicle.

3. Inspect and Repair

Clean the steering rack area thoroughly to remove any debris.
Inspect the steering rack seals and gaskets for damage.
If the seals are worn, replace them with new OEM seals following the manufacturer’s specifications.
Check for any damaged hoses and replace if necessary.

4. Reinstall the Steering Rack

Position the steering rack back into place and secure it with the mounting bolts.
Torque the bolts to the manufacturer’s specifications (usually between 20-30 ft-lbs).
Reconnect the power steering lines, ensuring they are tight to prevent leaks.
Reattach the tie rod ends and torque them to the manufacturer's specifications.

5. Fill Power Steering Fluid

Reconnect the negative terminal of the battery.
Fill the power steering reservoir with the recommended fluid type (Tesla specifies a specific fluid for the Model Y).
Turn the steering wheel from lock to lock several times to purge air from the system.

6. Final Checks

Reinstall the splash shields and front wheels.
Check for leaks around the steering rack and power steering lines after filling the fluid.
Perform a test drive to ensure proper steering function.
