Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues during the repair.

2. Remove the Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel lug nuts using a socket and wrench.
Take off the wheel and set it aside.

3. Remove the CV Joint

Locate the CV joint and assess the fasteners securing it to the axle.
Use a socket set to remove the axle nut and any bolts connecting the CV joint to the transmission or wheel hub.
Carefully pull the CV joint out from the axle, ensuring not to damage surrounding components.

4. Inspect and Replace Components

Inspect the CV joint for wear or damage, including the bearings and cage.
If faulty, replace the entire CV joint or axle as necessary.
Clean and prepare the new CV joint, applying fresh grease if required.

5. Reinstall the CV Joint

Position the new or repaired CV joint into place.
Reattach the axle nut and tighten it to the manufacturer’s specified torque (usually around 200 ft-lbs).
Reconnect any bolts removed during disassembly.

6. Reassemble the Wheel

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Fully tighten the lug nuts in a crisscross pattern to the manufacturer's specifications.

7. Final Checks

Reconnect the battery.
Start the vehicle and check for any unusual noises while turning the steering wheel.
