Solution

1. Preparation

Tools Required:
- Socket set
- Wrench set
- Fluid catch pan
- Power steering fluid
- Torque wrench
Ensure the vehicle is parked on a level surface and the engine is off. Disconnect the negative battery cable for safety.

2. Locate the Leak

Place a fluid catch pan under the power steering pump and inspect the system for leaks.
Clean the area around the suspected leak with a cloth to identify the source accurately.

3. Replace Damaged Components

3.1. Replace Power Steering Hoses
- Loosen and remove the clamps securing the power steering hoses to the pump and steering gear.
- Remove the old hoses and replace them with new ones, ensuring proper routing.
- Tighten the clamps to the manufacturer's specified torque (usually around 15-25 in-lbs).
3.2. Replace Power Steering Pump (if necessary)
- Disconnect the electrical connector from the power steering pump.
- Remove the bolts securing the pump to the mounting bracket and lift it out.
- Install the new pump, ensuring all connections are secure and torqued to specification (typically around 15-20 ft-lbs).

4. Refill and Bleed the System

Fill the power steering reservoir with the recommended fluid type (check owner's manual for specifications).
Start the engine and turn the steering wheel from lock to lock several times to bleed any air from the system.
Check fluid levels again and top off as necessary.

5. Final Checks

Reconnect the negative battery cable.
Start the vehicle and check for leaks around the repaired areas.
Test drive to ensure steering functions smoothly without noise.
