Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Wear safety gloves and goggles.

2. Inspect and Tighten Suspension Components

Tools Required: Socket set, torque wrench, jack stands, and a floor jack.
Raise the vehicle using a floor jack and secure it with jack stands.
Inspect all suspension components (shocks, struts, control arms) for damage.
Tighten any loose fasteners to manufacturer specifications using a torque wrench.

3. Replace Damaged Suspension Parts

If any components are found to be damaged:
- Tools Required: Wrenches, sockets, replacement parts.
- Remove the damaged component (e.g., strut or control arm) by unbolting it from its mounting points.
- Install the new component, ensuring all bolts are torqued to specifications.

4. Inspect and Replace CV Joints (if necessary)

If CV joints are suspected:
- Tools Required: Pliers, socket set, replacement CV joint or axle.
- Remove the wheel and inspect the CV joint for tears in the boot or damage.
- If damaged, remove the axle and replace it with a new one, ensuring proper installation.

5. Reassemble and Lower Vehicle

Reinstall the wheel and lower the vehicle.
Ensure all components are secure and recheck the lug nut torque.
