Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Wear safety gloves and goggles.

2. Check Power Steering Fluid

Open the hood and locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be within the marked range.
If low, top off with manufacturer-recommended power steering fluid.

3. Inspect for Leaks

Visually inspect power steering hoses and connections for signs of fluid leaks.
If leaks are found, replace the affected hoses or fittings. Use a socket set to remove and replace components as necessary.

4. Test Power Steering Pump

Start the engine and turn the steering wheel fully left and right to observe fluid circulation.
If the fluid is aerated or the pump is making noise, replace the power steering pump.
Disconnect the pump using a wrench, and install the new pump, ensuring to torque the bolts to manufacturer specifications.

5. Examine Steering Rack

If issues persist, inspect the steering rack for wear or damage.
Remove the steering rack using a socket set and inspect for play or leaks.
Replace the steering rack if damaged, and ensure all connections and alignments are correct during installation.
