Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to avoid any electrical issues during repair.

2. Inspect and Replace Power Steering Fluid

Tools Required: Fluid pump, funnel
Check the power steering fluid reservoir for low fluid levels.
If the fluid is low, top it off with the manufacturer's recommended power steering fluid.
If the fluid appears contaminated, proceed to flush and replace it.

3. Inspect and Replace Steering Components

Tools Required: Socket set, torque wrench
Raise the front of the vehicle using a jack and secure it with jack stands.
Remove the front wheels to access the steering components.
Inspect tie rods and ball joints for wear. If damaged, remove the old components using a socket set.
Install new tie rods or ball joints and torque to manufacturer specifications.

4. Check and Replace Wheel Bearings (if needed)

Tools Required: Wheel bearing puller, socket set
Spin each front wheel to check for noise or roughness – if found, remove the wheel.
Use a wheel bearing puller to remove the old bearings from the hub.
Install new bearings and ensure they are seated properly.

5. Reassemble and Test

Reinstall the front wheels and lower the vehicle.
Reconnect the battery, start the engine, and turn the steering wheel to check for noise.
Test drive to ensure the grinding noise is resolved.
