Solution

1. Preparation

Gather tools and parts required for inspection and potential replacement.
Safety gear: Gloves and goggles.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.

2. Inspect Suspension Components

Sub-steps:
- Lift the front of the vehicle using a jack and secure it with jack stands.
- Visually inspect control arms, bushings, and struts for wear or damage.
- Shake the wheel from side to side and up and down to check for play in the suspension.

3. Check CV Joints and Axles

Sub-steps:
- Remove the wheel and inspect the CV joint boots for cracks or tears.
- Check the joint itself for any excessive play or noise by moving it back and forth.
- If a CV joint is damaged, remove the axle and replace the joint or the complete axle as necessary.

4. Examine Steering Linkage

Sub-steps:
- Inspect the tie rods and steering rack for looseness or damage.
- Wiggle the steering wheel slightly and observe if there’s any movement in the steering components.
- Replace any worn tie rods or steering components as needed.

5. Tire Inspection

Sub-steps:
- Inspect tire tread for uneven wear patterns that could indicate alignment issues.
- Check tire pressure and adjust to manufacturer specifications.
- Rotate tires if uneven wear is detected or replace if tires are excessively worn.
