Solution

1. Preparation

Gather necessary tools and parts.
Safely lift the vehicle and support it on jack stands.
Disconnect the battery to avoid any electrical issues during the repair.

2. Remove Wheel and Brake Components

Sub-steps:
1. Use a socket set to remove the lug nuts and take off the wheel.
2. If necessary, remove the brake caliper and rotor for better access to the CV joint.
3. Secure the brake components to avoid stress on the brake line.

3. Remove the CV Joint

Sub-steps:
1. Locate the axle nut at the center of the wheel hub and remove it using a breaker bar and socket.
2. Disconnect the lower control arm or hub assembly to free the CV joint from the assembly.
3. Carefully pull the CV joint from the transmission/transfer case while ensuring no damage to surrounding components.

4. Inspect and Replace

Sub-steps:
1. Inspect the removed CV joint for wear, including the condition of the race and bearings.
2. If damaged, replace the CV joint assembly or boot as necessary.
3. Apply new grease to the joint if reusing, or ensure it's pre-greased for a new unit.

5. Reassemble Components

Sub-steps:
1. Reinsert the CV joint back into the transmission/transfer case.
2. Reattach the lower control arm or hub assembly and torque the fasteners to manufacturer specifications (check service manual for specific torque values).
3. Reinstall the axle nut and torque to manufacturer specifications.

6. Reinstall Brake Components and Wheel

Sub-steps:
1. Reinstall the brake rotor and caliper.
2. Reattach the wheel and torque the lug nuts in a crisscross pattern.
3. Reconnect the battery.
