Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and safely supported with jack stands.
Disconnect the battery if working on electrical components.

2. Check Power Steering System

Sub-step 1: Locate the power steering reservoir and check fluid levels.
Sub-step 2: If low, top off with the manufacturer-specified power steering fluid.
Sub-step 3: Inspect for leaks in hoses and connections.

3. Inspect and Replace CV Joints

Sub-step 1: Raise the vehicle and remove the front wheels for better access.
Sub-step 2: Inspect the CV joint boots for tears or cracks.
Sub-step 3: If damaged, remove the axle nut and disconnect the CV joint from the hub assembly.
Sub-step 4: Replace with a new CV joint assembly if necessary.
Sub-step 5: Reassemble by reversing the removal steps and torque the axle nut to the manufacturer’s specification (typically around 150 lb-ft).

4. Check and Replace Wheel Bearings

Sub-step 1: While the wheel is off, grasp the wheel at 12 and 6 o'clock and shake it to check for play.
Sub-step 2: If there is excessive play, remove the brake caliper and rotor.
Sub-step 3: Remove the wheel bearing hub assembly and replace it with a new one.
Sub-step 4: Reassemble and torque all bolts to the manufacturer’s specifications.

5. Inspect Steering Components

Sub-step 1: Visually inspect tie rods and ball joints for wear.
Sub-step 2: If any components are worn, replace them as needed.
Sub-step 3: Ensure all bolts are tightened to the proper torque settings.
