Solution

1. Preparation

Gather tools: socket set, torque wrench, jack stands, and a power steering fluid reservoir.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Inspect and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check fluid level; top up if low with manufacturer-recommended fluid.
If fluid is dirty or contaminated, drain the old fluid and replace it.
Reconnect the reservoir cap.

3. Inspect Steering Components

Raise the vehicle using jack stands.
Check the steering rack for any signs of leakage or physical damage.
Inspect the tie rod ends for play; replace if movement is observed.
Tighten any loose connections according to manufacturer specifications.

4. Replace Steering Pump (if necessary)

If the pump is found to be faulty, locate the power steering pump.
Disconnect the power steering hoses using a wrench and retain any fluid.
Remove mounting bolts with a socket set and take out the pump.
Install the new pump, ensuring all connections are secure and refill with fluid.

5. Test and Align

Lower the vehicle and reconnect the battery.
Start the engine and turn the steering wheel from lock to lock to bleed air from the system.
Test drive the vehicle to ensure the grinding noise has ceased.
If necessary, have the wheel alignment checked and adjusted.
