Solution

1. Preparation

Tools Required: OBD-II scanner, fluid catch pan, wrench set, torque wrench, power steering fluid, flashlight.
Disconnect the battery to ensure safety while working on the electrical components.

2. Inspect Power Steering Fluid

Locate the power steering reservoir under the hood.
Check the fluid level against the minimum and maximum marks.
If low, top up with the recommended power steering fluid (consult the owner's manual for specifications).

3. Check for Leaks

Use a flashlight to inspect hoses and connections for any signs of fluid leaks.
If leaks are found, mark the areas for replacement.
Replace any damaged hoses or seals as necessary.

4. Test Power Steering Pump

Reconnect the battery.
Start the engine and allow it to idle.
With the engine running, turn the steering wheel from lock to lock.
Listen for unusual noises from the pump and feel for any inconsistencies in steering assist.
If the pump is noisy or does not provide adequate assist, replace the power steering pump.

5. Inspect Steering Rack

Lift the vehicle using a jack and secure it with jack stands.
Inspect the steering rack for any signs of wear, damage, or looseness.
If excessive play is found, the steering rack may need to be replaced.

6. Reassemble and Refill

If any parts were removed for inspection or replacement, reinstall them securely.
Refill the power steering fluid if it was drained during inspection.
Ensure all connections are tight and free of leaks.
