Solution

1. Preparation

Gather tools: jack stands, socket set, torque wrench, pry bar, and safety goggles.
Ensure the vehicle is on a flat surface and secure with parking brake engaged.

2. Inspect and Replace Worn Components

Inspect Suspension and Steering Components
- Remove the front wheels using a socket set.
- Check control arms and bushings for cracks or excessive wear. Replace if necessary.
- Use a pry bar to check for play in the components.
Check and Replace CV Joints
- Inspect the outer CV joints for torn boots or grease leakage.
- If damaged, remove the axle from the hub and replace the CV joint or the entire axle assembly.
Examine and Replace Wheel Bearings
- Spin the wheel hub by hand to detect noise or roughness.
- If defective, remove the hub assembly and replace the wheel bearings. Ensure proper torque specifications are followed during reassembly.
Inspect Power Steering System
- Check fluid levels; top off with appropriate power steering fluid if low.
- Look for leaks in the hoses and connections; replace any damaged components.
Reassemble and Torque Components
- Reattach the wheels and torque lug nuts to the manufacturer’s specifications (typically around 80-100 lb-ft).
- Lower the vehicle carefully from jack stands.
