Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Inspect and Replace Hoses

Inspect Hoses:
- Visually check all power steering hoses for cracks or leaks.
- Use a flashlight to inspect hard-to-see areas.
Replace Damaged Hoses:
- If a hose is damaged, loosen the hose clamps with a screwdriver and remove the hose from the pump and steering gear.
- Install the new hose by securing it with the clamps and ensuring tight connections.
- Ensure proper routing to avoid kinks.

3. Repair or Replace the Steering Pump

Inspect the Pump:
- Check for leaks around the pump seals.
Repair/Replace:
- If leakage is found, remove the pump by disconnecting the hoses and unbolting it from the engine.
- Install the new or rebuilt pump by bolting it in place and reconnecting the hoses securely.

4. Inspect and Repair Steering Gear

Check for Leaks:
- Examine the steering gear for fluid seepage.
Repair/Replace:
- If leakage is found, consider re-sealing the steering gear or replacing it if damage is extensive.
- Follow specific manufacturer instructions for reassembly.

5. Refill Power Steering Fluid

Refill the power steering reservoir with the recommended type of power steering fluid.
Start the engine and turn the steering wheel from lock to lock to purge air from the system.

6. Final Checks

Inspect all connections for leaks after refilling.
