Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts using a lug wrench.
2. Elevate the vehicle using a jack and secure it with jack stands.
3. Completely remove the lug nuts and take off the wheel.

3. Remove CV Joint

Sub-steps:
1. Remove the axle nut using a socket wrench (usually a large size, e.g., 30mm).
2. Disconnect any components obstructing the CV joint, such as the lower ball joint or tie rod end, using appropriate tools.
3. Pull the CV axle out of the hub assembly gently, being careful not to damage the bearing.

4. Inspect and Replace CV Boot

Sub-steps:
1. Clean the CV joint with a degreaser to remove old grease.
2. Inspect the joint for wear; if damaged, replace the entire joint.
3. If only the boot is damaged, remove the old boot by cutting it off.
4. Apply new grease to the CV joint as specified by the manufacturer.
5. Install the new CV boot over the joint and secure it with clamps.

5. Reassemble Components

Sub-steps:
1. Insert the CV axle back into the hub assembly.
2. Reattach the lower ball joint or tie rod end if disconnected.
3. Tighten the axle nut to the manufacturer’s torque specifications (usually around 150-200 ft-lbs).
4. Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Torque Lug Nuts

Sub-steps:
1. Lower the vehicle off the jack stands.
2. Torque the lug nuts to the specified settings (usually around 76 ft-lbs).
