Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and cool.

2. Inspect Fluid Leaks

Check the power steering fluid reservoir. If low, top up with the recommended fluid (check owner’s manual for specifications).
Clean any visible leaks with a cloth to identify the source after a short test drive.

3. Replace Damaged Components

Steering Rack Replacement:
- Disconnect the negative battery terminal to avoid electrical shorts.
- Remove the steering column shaft from the steering rack.
- Disconnect the power steering lines from the rack; use a wrench to avoid damage.
- Unbolt the steering rack from its mounting points (torque specifications can be found in the service manual).
- Remove the old steering rack and replace it with a new one, securing it with the bolts.
- Reconnect the power steering lines, ensuring they are tight and leak-free.

4. Refill and Bleed the System

Fill the power steering reservoir with the appropriate fluid.
Turn the steering wheel from lock to lock several times to purge air from the system.
Check fluid levels again and top off as necessary.

5. Final Inspection

Recheck all connections for leaks after the vehicle has been operated for a short period.
Inspect the area around the steering rack to ensure no fluid is leaking.
