Solution

1. Preparation

Gather tools: socket set, jack and jack stands, mechanic's stethoscope, and torque wrench.
Ensure the vehicle is parked on a flat surface, and the engine is off.
Disconnect the battery for safety.

2. Raise the Vehicle

Use the jack to lift the front of the vehicle.
Secure with jack stands to ensure stability.

3. Inspect and Replace CV Joint

Inspect: Remove the wheel and visually inspect the CV joint and boot.
Replace: If the boot is damaged, remove the axle nut using a socket wrench.
- Separate the CV joint from the hub and slide it out.
- Install the new CV joint by reversing the removal steps.
- Torque the axle nut to manufacturer's specifications (usually around 150-200 Nm).

4. Check and Replace Suspension Components

Inspect: Examine control arms, bushings, and tie rod ends. Look for cracks, excessive wear, or play.
Replace: If components are damaged:
- Use a socket set to remove the affected part.
- Install new parts, ensuring all bolts are torqued to specifications.

5. Reassemble and Lower the Vehicle

Reinstall the wheel and lower the vehicle back to the ground.
Torque wheel lug nuts to the manufacturer's specifications (typically around 100 Nm).
