Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, OBD-II scanner, flashlight.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the 12V battery to ensure safety while working on electrical components.

2. Inspect Suspension Components

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels using a lug wrench.
3. Visually inspect the struts, control arms, and sway bar links for damage or excessive play.
4. Check the bushings for cracks or deterioration.

3. Replace Damaged Components

Sub-steps:
1. If any suspension components are found to be damaged, remove the bolts securing the component with a socket set.
2. Replace the component with a new part, ensuring to align it properly.
3. Torque the bolts to the manufacturer's specifications (consult service manual for specific torque values).
4. Reinstall the wheels and lower the vehicle.

4. Inspect and Replace CV Joints (if necessary)

Sub-steps:
1. If CV joints are suspected, remove the axle nut and disconnect the drive axle from the wheel hub.
2. Inspect the CV boots for tears and the joint for play.
3. If damaged, replace the CV joint or axle assembly as necessary.
4. Reassemble by reversing the disassembly steps and torquing the axle nut to the correct specification.
