Raise the vehicle using a jack and secure it with jack stands.
Remove the front wheels to gain access to the steering components.
Disconnect the steering linkage from the steering rack.
Remove any electrical connectors or sensors attached to the steering rack.
Unbolt the steering rack from its mounting points and carefully slide it out.

3. Inspect and Replace Seals

Examine the steering rack for damaged seals or boots.
If leaks are present, remove the old seals using a seal puller or flathead screwdriver.
Clean the sealing surfaces on the steering rack.
Install new seals (ensure they are compatible with the Model Y) and reassemble the steering rack components.

4. Reinstallation

Reverse the removal steps to install the steering rack back into the vehicle.
Ensure all bolts are tightened to manufacturer's torque specifications.
Reconnect the steering linkage and any electrical connectors.

5. Refill and Bleed Power Steering System

Refill the power steering fluid reservoir with the recommended fluid type.
Start the engine and turn the steering wheel from lock to lock to bleed any air from the system.
Check the fluid level again and top off if necessary.
