Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Gather necessary tools and parts.

2. Raise the Vehicle

Use a jack to lift the front of the vehicle and secure it on jack stands.
Remove the front wheels to gain access to the suspension components.

3. Inspect and Replace CV Joints (if necessary)

Inspection:
- Check the outer CV joint for any damage or torn boots.
- If damaged, proceed to replace.
Replacement:
- Remove the retaining clip and unscrew the axle nut using a socket.
- Detach the lower control arm from the knuckle to free the axle.
- Slide the axle out of the transmission and replace with a new one.
- Reassemble in reverse order, ensuring the axle nut is torqued to manufacturer specifications (usually around 30-50 ft-lbs).

4. Examine and Replace Suspension Components (if necessary)

Check the struts, control arms, and bushings for signs of wear.
If any components are worn:
- Control Arm Replacement:
  - Remove the bolts securing the control arm to the subframe and steering knuckle.
  - Replace the control arm and torque bolts to specifications (usually around 40-60 ft-lbs).
- Strut Replacement:
  - Remove the top strut bolts in the engine compartment.
  - Detach the bottom strut mount from the knuckle.
  - Replace with new struts and torque fasteners as required.

5. Reassemble and Lower the Vehicle

Reinstall the wheels and lower the vehicle from the jack stands.
Tighten lug nuts to the manufacturer’s torque specifications (typically 80-100 ft-lbs).
