Safety gear: gloves and safety glasses.

2. Inspect and Replace CV Joints

Inspect CV Joints:
- Lift the front end of the vehicle securely on jack stands.
- Remove the front wheels using a socket set.
- Visually inspect CV joint boots for tears or grease leaks.
Replace CV Joint (if necessary):
- Remove the axle nut using a breaker bar and socket.
- Disconnect the lower control arm at the ball joint.
- Remove the axle from the transmission.
- Install the new CV joint by reversing the removal process.
- Torque the axle nut to the manufacturer's specifications (usually around 200 Nm).

3. Check and Replace Suspension Components

Inspect Suspension:
- Examine control arms, bushings, and ball joints for wear.
Replace Worn Components:
- Remove any components that are worn or damaged using appropriate tools.
- Install new control arms or bushings as needed and torque to specifications.
- Reassemble suspension and ensure everything is securely fastened.

4. Final Assembly

Reattach the wheels and lower the vehicle.
Tighten wheel lug nuts to the specified torque (typically 120 Nm).
Reconnect the battery if it was disconnected.
