Solution

1. Preparation

Tools Required: 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 engine is off.
Disconnect the battery to prevent electrical shorts during inspection.

2. Inspect and Replace CV Joints

Lift the Vehicle:
- Use a jack to lift the vehicle and secure it with jack stands.
- Ensure the vehicle is stable before proceeding.
Remove the Wheel:
- Use a socket set to remove the lug nuts and take off the wheel.
Inspect the CV Joint:
- Check the CV joint boots for any cracks or leaks.
- If damaged, proceed to replace the CV joint.
Remove the CV Joint:
- Use a socket set to remove the axle nut.
- Carefully pull the axle out of the hub assembly.
- Use a pry bar if needed to separate the axle from the transmission.
Install New CV Joint:
- Insert the new CV joint into the hub assembly and secure it with the axle nut, following the manufacturer's torque specifications (typically around 30-50 ft-lbs).
- Reinstall the wheel and lug nuts, tightening them in a star pattern.

3. Inspect and Replace Suspension Components

Inspect Tie Rods and Ball Joints:
- Check for any excessive play or wear in the tie rods and ball joints using a pry bar.
Replace Worn Components:
- If any components are found to be worn, use a socket set to remove and replace them.
- Ensure to torque the new components to the manufacturer's specifications.

4. Reassemble and Lower Vehicle

Reinstall the wheel and lug nuts.
Lower the vehicle back to the ground.
Reconnect the battery.
