Safety gear including gloves and safety glasses.

2. Inspect and Replace Suspension Components

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels using a socket set.
3. Visually inspect the struts and control arms for any signs of wear or damage.
4. If any components are worn, remove the bolts securing them in place using a socket wrench.
5. Replace the damaged components with new parts, ensuring they are torqued to manufacturer specifications (typically around 70-80 ft-lbs for control arm bolts).

3. Check and Replace CV Joints

Sub-steps:
1. Carefully inspect the CV boots for cracks or tears.
2. If damaged, remove the axle nut and the axle from the hub.
3. Replace the CV joint or axle assembly as necessary, ensuring proper lubrication.
4. Reinstall the axle and torque the axle nut to the manufacturer specifications (usually around 150-180 ft-lbs).

4. Exhaust System Inspection
