Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Gather the necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Tighten Components

Sub-steps:
1. Raise the vehicle using a jack and secure with jack stands.
2. Inspect the undercarriage for loose bolts or connections, especially around the suspension and drivetrain.
3. Tighten any loose bolts to the manufacturer’s torque specifications using a torque wrench.

3. Check and Replace CV Joints (if necessary)

Sub-steps:
1. Remove the wheel to gain access to the CV joint.
2. Inspect the CV boot for tears or grease leakage. If damaged, replace the CV joint.
3. To replace, remove the axle nut using a socket set, detach the CV joint from the hub, and install the new joint ensuring proper alignment.
4. Reinstall the wheel and lower the vehicle.

4. Inspect and Replace Suspension Components (if necessary)

Sub-steps:
1. Check the struts and bushings for wear. If worn, detach the strut assembly.
2. Replace the struts/bushings with new components using a socket set to remove bolts.
3. Reassemble and torque to manufacturer specifications.

5. Reconnect Battery and Lower Vehicle

Sub-steps:
1. Reconnect the battery terminals.
2. Lower the vehicle from jack stands and perform a final check of all work done.
