Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, socket set, torque wrench, pry bar.
Ensure the vehicle is parked on a level surface and the engine is off. Use wheel chocks to prevent movement.

2. Inspect and Replace Suspension Components

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Remove the front and rear wheels to access suspension components.
3. Inspect struts and shock absorbers for leaks or damage.
4. Check control arms and bushings for cracks or wear; replace any damaged parts.
5. If struts are worn, remove them using a socket set, replace with new struts, and torque bolts to manufacturer specifications (usually around 50-70 ft-lbs).

3. Check and Repair Exhaust System

Sub-steps:
1. Inspect the entire exhaust system for loose connections, especially at the joints and hangers.
2. Tighten any loose bolts or replace damaged hangers.
3. If there are any holes or cracks in the exhaust pipes, use an exhaust repair patch or replace the affected section.

4. Inspect and Replace CV Joints and Axles

Sub-steps:
1. Remove the wheels and check the CV boots for tears or leaks.
2. If CV joints are damaged, remove the axle using a socket set, replace with new CV axle, and torque to specifications.
3. Reinstall the wheels after all repairs and lower the vehicle.
