Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Check Power Steering Fluid

Remove the power steering fluid reservoir cap.
Inspect the fluid level; top off if low with the manufacturer-recommended fluid.
Check fluid condition; if dirty or contaminated, proceed to fluid replacement.

3. Inspect and Replace Power Steering Fluid

Place a drain pan under the power steering pump.
Disconnect the return hose from the pump and drain old fluid.
Reconnect the hose and fill the reservoir with new fluid.
Cycle the steering from lock to lock to purge air.

4. Inspect the Power Steering Pump

Remove the pump drive belt using a socket set.
Unbolt the power steering pump and remove it from the vehicle.
Examine for any signs of wear or leakage; replace if necessary.
Install the new pump and tighten bolts to manufacturer specifications.

5. Inspect the Steering Rack

Visually inspect the steering rack for damage or leaks.
If noise persists, consider disassembly and inspection for internal wear.
Replace any damaged components as necessary.

6. Reinstall Serpentine Belt (if removed)

Ensure proper tension on the belt and align it with all pulleys.
Use a torque wrench to secure any bolts per manufacturer specifications.
