Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the 12V battery to ensure safety while working with electrical components.

2. Inspect and Replace Power Steering Fluid

Sub-step 1: Remove the power steering fluid reservoir cap and check the fluid level.
Sub-step 2: If low, add the recommended type of power steering fluid (refer to the owner's manual for specifications).
Sub-step 3: If fluid is contaminated or burnt, fully drain the system and replace with new fluid.

3. Inspect Steering Components

Sub-step 1: Remove the front wheels to access the steering and suspension components.
Sub-step 2: Visually inspect for worn tie rods, ball joints, and bushings. Replace any parts that show signs of wear.
Sub-step 3: Tighten any loose fasteners and ensure all components are securely attached.

4. Test Wheel Bearings

Sub-step 1: Spin each wheel by hand and listen for any grinding noise indicative of bad wheel bearings.
Sub-step 2: If noise is present, replace the wheel bearings as necessary.

5. Reassemble and Reconnect Battery

Sub-step 1: Reinstall the front wheels and tighten lug nuts to the manufacturer's torque specifications.
Sub-step 2: Reconnect the 12V battery and ensure all connections are secure.
