Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, add the appropriate fluid (e.g., CHF 202 or equivalent).
Inspect the fluid for contamination; if dirty, consider flushing the system.

3. Inspect and Replace Power Steering Hoses

Visually inspect all power steering hoses for cracks or leaks.
If any hoses are damaged, use a socket set to remove the old hoses.
Install new hoses and secure them with appropriate clamps, ensuring no twists or kinks.

4. Examine Steering Rack and Pinion

Lift the front of the vehicle using a jack and secure it with jack stands.
Inspect the steering rack for any signs of damage or fluid leaks.
If damaged, remove the steering rack by disconnecting it from the subframe and steering column (note the torque specifications for reinstallation).

5. Test and Replace Steering Pump

Inspect the steering pump for noise while the engine is running.
If the pump is noisy, remove it by disconnecting the fluid lines and mounting bolts.
Install a new pump and refill the system with power steering fluid.

6. Reassemble and Test

Reconnect the battery and lower the vehicle.
Start the engine and turn the steering wheel from lock to lock to bleed air from the system.
Check for any noises during operation.
