Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface, engage the parking brake, and place wheel chocks behind the rear wheels.

2. Inspect and Replace CV Joints (if necessary)

Tools Required: Socket set, torque wrench, pry bar, CV joint puller.
Sub-steps:
1. Remove the front wheel on the affected side using the socket set.
2. Disconnect the lower control arm from the steering knuckle to gain access to the CV joint.
3. Inspect the CV joint boot for tears; if damaged, use the CV joint puller to remove the joint.
4. Replace the CV joint with a new one, ensuring it is properly lubricated and the boot is secured.
5. Reassemble the lower control arm and torque to manufacturer specifications.

3. Inspect and Replace Suspension Components (if necessary)

Tools Required: Socket set, torque wrench, suspension tool kit.
Sub-steps:
1. Remove the front wheels for better access to the suspension components.
2. Inspect the control arms, bushings, and strut mounts for wear or damage.
3. If any components show signs of wear, remove them using the socket set and replace them with new parts.
4. Reattach all components, torque to specifications, and ensure proper alignment is maintained.

4. Final Assembly

Tools Required: Torque wrench.
Sub-steps:
1. Replace the front wheels and lower the vehicle back to the ground.
2. Tighten the lug nuts in a crisscross pattern to the specified torque.
3. Perform a final inspection of all replaced components to ensure they are secure.
