Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical short.

2. Inspect and Replace CV Joints

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Remove the front wheels using a socket set (usually a 21mm socket).
3. Inspect the CV boots for tears or leaks; if damaged, proceed to replace the CV joint.
4. Remove the axle nut (using a socket set) and the control arm bolts.
5. Pull the CV joint out of the transmission or differential and replace it with a new joint.
6. Reassemble in reverse order, ensuring to torque the axle nut to manufacturer specifications (typically 150 ft-lbs).

3. Check Steering Components

Sub-steps:
1. Inspect the tie rod ends for play or damage; replace if necessary.
2. Tighten any loose bolts in the steering linkage.
3. Replace worn or damaged bushings in control arms or sway bars.
4. Reassemble all components and ensure proper alignment.

4. Inspect Suspension Components

Sub-steps:
1. Visually check the struts and shocks for leaks or damage.
2. Replace any worn struts or shocks if necessary.
3. Verify that all bolts and nuts are tightened to manufacturer specifications.
4. Reinstall front wheels and lower the vehicle.
