Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is on a flat surface and securely raised using jack stands.
Disconnect the battery to prevent electrical issues during repairs.

2. Inspect and Replace Worn Suspension Components

Inspect Components:
- Examine control arms, tie rods, and bushings for any signs of wear, cracks, or breaks.
Replace as Necessary:
- If any components are damaged, remove the fasteners using a socket set and replace them with new parts.
- Torque new components to manufacturer specifications (check the service manual for values).

3. Inspect and Replace CV Joints or Axles

Remove Wheels:
- Use a jack and jack stands to lift the vehicle and remove the front wheels.
Inspect CV Joints:
- Check the outer and inner CV joints for any tears in the boot or excessive play.
Replace if Necessary:
- If damaged, remove the axle nut and unbolt the CV joint from the wheel hub; install a new CV joint or axle and torque to specifications.

4. Inspect and Replace Wheel Bearings

Check Bearings:
- Spin the wheel to listen for roughness or grinding sounds from the bearing.
Replace if Necessary:
- Remove the wheel hub assembly using a socket set and replace the bearing.
- Press in a new bearing and reassemble the hub, ensuring proper torque settings.
