Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool before starting any inspections.

2. Inspect Power Steering Fluid Reservoir

Locate the power steering fluid reservoir under the hood.
Remove the cap and check the fluid level against the markings on the reservoir.
If the fluid is low, top it up with the manufacturer-recommended power steering fluid.

3. Check Hoses and Connections

Visually inspect all power steering hoses for cracks, fraying, or leaks.
Ensure all hose clamps are tight and secure.
If any hoses are damaged, replace them with OEM or quality aftermarket parts.

4. Inspect Power Steering Pump and Steering Gear

Locate the power steering pump and check for any signs of leaking fluid around the pump body and connections.
Check the steering gear assembly for leaks where it connects to the steering rack.
If leaks are found, replace the affected components (pump or gear assembly) as needed.

5. Inspect Steering Rack Boots

Examine the rubber boots at the ends of the steering rack for tears or damage.
If fluid is present inside the boot, the seals may be leaking, requiring replacement of the steering rack.

6. Use UV Dye for Leak Detection

If no visible leaks are found, add a UV dye to the power steering fluid.
Run the engine and turn the steering wheel to circulate the fluid.
Use a UV light to inspect for leaks; any leaks will fluoresce under the light.
