Solution

1. Preparation

Gather tools: jack and jack stands, socket set, torque wrench, pry bar, and OBD-II scanner.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to avoid any electrical issues while working.

2. Inspect and Replace CV Joints

Use the jack to lift the front of the vehicle and secure it with jack stands.
Remove the wheel using a socket set.
Check the CV joint boots for cracks or leaks; if damaged, proceed to replace the CV joint.
- Sub-steps:
  - Remove the axle nut using a socket and breaker bar.
  - Disconnect the lower control arm to free the CV joint from the hub.
  - Slide the old CV joint out and insert the new one, making sure it is properly seated.
  - Reassemble the lower control arm and torque the axle nut to the manufacturer's specifications (typically 250 Nm).

3. Inspect and Replace Suspension Components

Check the strut mounts and sway bar links for wear.
If damaged, replace them as follows:
- Sub-steps:
  - Remove any components obstructing access to the strut mount and sway bar links.
  - Use a socket set to remove bolts securing the strut mount and sway bar link.
  - Install new components, ensuring all bolts are tightened to the specified torque (typically 30-40 Nm for sway bar links).

4. Reassemble and Lower the Vehicle

Reinstall the wheel and tighten the lug nuts in a crisscross pattern to ensure even pressure.
Lower the vehicle from the jack stands and torque the lug nuts to the specified value (usually 120 Nm).
