Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely raised on jack stands.
Disconnect the battery if necessary for electrical components.

2. Inspect Power Steering System

Check fluid level: Remove the power steering fluid reservoir cap; ensure fluid is at the recommended level.
Fluid condition: If fluid is dark or has debris, perform a fluid change.

3. Examine CV Joints and Axles

Visual Inspection: Look for torn CV boots or grease leakage.
Remove and Replace: If damaged, remove the axle nut using a socket set. Disconnect the axle from the wheel hub and replace the CV joint or the entire axle if necessary.

4. Check Suspension Components

Inspect Control Arms: Look for cracks or severe wear on bushings.
Replace Worn Components: Remove the control arm bolts using a torque wrench, replace the bushings or control arm as needed, and reassemble.

5. Inspect Wheel Bearings

Visual and Tactile Check: Spin the wheel and listen for noise or feel for roughness.
Replace if Damaged: If bearings are worn, remove the wheel hub and replace the bearings using a bearing puller.

6. Inspect Brake Components

Check Pads and Rotors: Look for uneven wear or damage.
Replace if Necessary: Remove the caliper and replace worn brake pads or rotors with new components.
