2. Inspect and Replace CV Joints

Lift the Vehicle: Use a jack and secure it on jack stands.
Remove the Wheel: Use a socket set to remove the lug nuts and take off the front wheel.
Inspect CV Boots: Check for any cracks or tears in the CV boot.
- If damaged, proceed to replace the CV joint.
Remove the CV Joint:
- Unbolt the CV joint from the wheel hub and axle.
- Pull out the CV joint from the differential side.
Install New CV Joint:
- Apply grease to the new CV joint and insert it into the differential.
- Reattach the CV joint to the wheel hub and secure it with the bolts.
Reassemble:
- Reinstall the wheel and lower the vehicle from the jack stands.

3. Inspect and Replace Wheel Bearings (if necessary)

Remove the Brake Caliper: Use a socket set to unbolt and remove the brake caliper.
Remove the Brake Rotor: Take off the rotor to access the bearing.
Inspect Wheel Bearing: Check for any excessive play or roughness in the bearing.
- If faulty, remove the bearing using a bearing puller.
Install New Bearing:
- Press or tap the new bearing into place using a bearing installer.
Reassemble:
- Reinstall the brake rotor and caliper, ensuring all bolts are torqued to specifications.
