Solution

1. Preparation

Tools Required: Floor jack, jack stands, socket set, torque wrench, fluid catch basin, power steering fluid.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts during inspection.

2. Check Power Steering System

Inspect the power steering fluid reservoir for proper fluid level.
If low, top off with manufacturer-recommended power steering fluid.
Check for leaks in hoses and connections. Replace any damaged hoses.

3. Inspect Steering Components

Lift the front of the vehicle using a floor jack and secure it with jack stands.
Visually inspect tie rods, ball joints, and steering rack for any signs of wear or damage.
Replace any worn components with OEM parts.

4. Examine Wheel Bearings

Rotate each wheel by hand to check for roughness or grinding noise.
If noise is present, the wheel bearing may need replacement. Remove the wheel and brake rotor to access the bearing.
Replace the bearing and reassemble components, ensuring proper torque specifications are followed.

5. Inspect CV Joints

Check the outer and inner CV joints for any signs of boot damage or grease leakage.
If damaged, replace the CV joint or axle as necessary.

6. Reassemble and Test

Reinstall any components removed during inspection or repair.
Ensure all bolts are tightened to the manufacturer’s specifications.
Reconnect the battery and lower the vehicle.
Test drive to verify that the grinding noise has been resolved.
