Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid electrical shorts.
Gather necessary tools and parts.

2. Check Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the recommended power steering fluid (refer to the owner's manual).

3. Inspect for Leaks

Examine hoses and connections leading to the power steering pump for any signs of leaks.
If leaks are found, replace the affected hoses or seals.

4. Test Power Steering Pump

With the engine running, listen for abnormal noises from the power steering pump.
If noise is present, replace the power steering pump.
To replace, drain the fluid, disconnect the pump, and install a new pump using appropriate torque specifications (usually around 18-25 ft-lbs).

5. Inspect Steering Rack

Lift the front of the vehicle using a jack and secure it with jack stands for safety.
Check the steering rack for binding or excessive play.
If issues are found, the steering rack should be replaced.

6. Reassemble and Refill

Reconnect any hoses and electrical connectors.
Refill the power steering system with fresh fluid, ensuring no air is trapped by turning the steering wheel from lock to lock several times.
Reconnect the battery.
