Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, mechanic's stethoscope, tire iron.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the battery if working on any electrical components.

2. Inspect and Replace Worn Components

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels using a tire iron.
3. Inspect the CV joints for any tears or grease leakage. If damaged, proceed to replace the CV axle.
  - Remove the axle nut (typically 30-36mm) using a socket.
  - Disconnect any retaining clips from the suspension or steering components.
  - Pull the CV axle out of the transmission and replace with a new axle.
4. Check the suspension components:
  - Look for leaks in shock absorbers and any play in control arms.
  - Replace any worn struts or shocks as necessary.
  - Tighten any loose bolts to manufacturer specifications.

3. Reassemble and Test

Sub-steps:
1. Reinstall the front wheels and torque the lug nuts to manufacturer specifications (usually around 80-90 ft-lbs).
2. Lower the vehicle back to the ground.
3. Reconnect the battery if it was disconnected.
4. Start the engine and check for any abnormal noises while turning the steering wheel left and right.
