Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.

2. Check Fluid Level

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; top off with the recommended power steering fluid if low.
Inspect the fluid for contamination (milky appearance) and change if necessary.

3. Inspect for Leaks

Visually inspect all power steering hoses and connections for signs of wear or leakage.
If a leak is found, replace the damaged hose or fitting.
Clean any spilled fluid to prevent slipping and further inspection.

4. Test Power Steering Pump

Reconnect the battery and start the engine.
Listen for any abnormal noises coming from the power steering pump.
If noise persists, replace the pump as it may be failing.

5. Inspect Steering Rack

Lift the vehicle using a jack and secure it on jack stands.
Check the steering rack for any signs of damage or fluid leaks.
If the rack is damaged, it should be replaced.

6. Check Serpentine Belt

Inspect the condition of the serpentine belt for wear or fraying.
Ensure the belt is tight and properly aligned; replace if necessary.
