Solution

1. Preparation

Gather tools and parts needed for the repair.
Safety glasses and gloves should be worn.
Park the vehicle on a flat surface and engage the parking brake.

2. Drain the Steering Fluid

Place a clean container under the steering fluid reservoir.
Remove the reservoir cap and siphon out the old fluid using a fluid extractor or turkey baster.
Dispose of the old fluid according to local regulations.

3. Inspect and Replace Damaged Components

Fluid Lines and Hoses:
- Disconnect the clamps holding the hoses in place using a hose clamp tool.
- Remove the damaged hoses and replace them with new ones, ensuring they are compatible with Tesla specifications.
- Reattach hoses and secure them with clamps, tightening to manufacturer specifications.
Steering Rack:
- If the steering rack is leaking, it will need to be replaced.
- Disconnect the battery to prevent electrical issues.
- Remove the undercarriage cover (if applicable) and disconnect the steering linkage.
- Unbolt the steering rack from its mounting points and remove it from the vehicle.
- Install the new steering rack and reattach the steering linkage, torquing bolts to manufacturer specifications.

4. Refill Steering Fluid

Refill the steering fluid reservoir with the recommended fluid type (check the owner’s manual for specifications).
Start the vehicle and turn the steering wheel from lock to lock several times to purge air from the system.

5. Test for Leaks

After refilling, inspect all connections for leaks while the vehicle is running.
If leaks are detected, ensure all connections are tight and components are properly installed.
