Solution

1. Preparation

Tools Required: Socket set, screwdrivers, fluid catch pan.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Hoses

Sub-steps:
1. Locate and remove the damaged power steering hoses using the socket set.
2. Clean the mounting surfaces to ensure a secure fit for the new hoses.
3. Install new hoses by connecting them to the reservoir and steering rack, ensuring a tight fit.
4. Torque the hose connections to the manufacturer's specifications (typically around 15-25 Nm for hose clamps).

3. Replace the Power Steering Pump (if leaking)

Sub-steps:
1. Remove the serpentine belt by loosening the tensioner.
2. Disconnect the power steering pump from the reservoir and the steering gear.
3. Remove the pump mounting bolts and take out the pump.
4. Install the new power steering pump in reverse order and reattach the serpentine belt.
5. Torque the mounting bolts to the specified value (usually around 25-30 Nm).

4. Check and Repair Steering Rack (if necessary)

Sub-steps:
1. If leaks are found at the steering rack, remove the rack by disconnecting the tie rods and steering column.
2. Inspect the seals and replace if worn.
3. Reinstall the steering rack and ensure all connections are secure.

5. Refill and Bleed the Power Steering System

Sub-steps:
1. Refill the power steering fluid reservoir with the manufacturer's recommended fluid (usually CHF 11S).
2. Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
3. Check the fluid level again and top off as necessary.
