Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical issues during the repair.

2. Remove the Steering Rack

Lift the vehicle using a jack and secure it with jack stands.
Remove the front wheels for easier access to the steering components.
Disconnect any hoses or lines attached to the steering rack, noting their positions for reinstallation.
Unbolt the steering rack from its mounting points and carefully remove it from the vehicle.

3. Inspect and Replace Seals

Clean the steering rack thoroughly to identify the source of the leak.
Remove the old seals from the steering rack using a seal puller.
Install new seals, ensuring they are seated properly and lubricated with power steering fluid.

4. Reinstall the Steering Rack

Place the repaired or new steering rack back into position.
Reattach all hoses and lines, ensuring that they are secure and properly torqued.
Bolt the steering rack to the mounting points, tightening to manufacturer specifications (typically around 20-30 Nm).

5. Refill Power Steering Fluid

Reconnect the battery.
Fill the power steering reservoir with the appropriate fluid as specified in the owner's manual.
Start the engine and turn the steering wheel from lock to lock to bleed air from the system.

6. Test for Leaks

Inspect all connections for any signs of leakage after the system has been pressurized.
Ensure the power steering fluid level is correct and top off if necessary.
