Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat, level surface and securely lifted.
Disconnect the battery for safety.

2. Inspect and Replace CV Joints (if necessary)

Remove the wheel:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts and take off the wheel.
Inspect CV joints:
- Check the inner and outer CV joints for any tears in the boots.
- If damaged, proceed to replace the CV joint.
Remove axle:
- Remove the axle nut using a socket and ratchet.
- Disconnect any retaining clips and slide the axle out of the hub.
Install new CV joint:
- Apply grease to the new joint and install it into the hub.
- Secure with the axle nut and torque to manufacturer specifications (typically around 150-200 lb-ft).

3. Inspect and Replace Suspension Components (if necessary)

Check ball joints and tie rods:
- Use a pry bar to apply pressure and test for play.
- If any components are worn, remove and replace them.
Replace ball joints:
- Remove the control arm from the vehicle.
- Press out the old ball joint using a ball joint separator and install the new one.
- Reinstall the control arm and torque to specifications.

4. Reassemble and Test

Reinstall wheel:
- Place the wheel back on and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to specifications (typically around 80-100 lb-ft).
Reconnect battery:
