Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar
Ensure the vehicle is on a flat surface.
Disconnect the battery if working near electrical components.

2. Inspect Suspension Components

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Remove the front wheels to gain access to suspension components.
3. Check the struts and shocks for leaks or damage.
4. Inspect control arms for any cracks or bent structures.
5. Use a pry bar to check for excessive play in the bushings and joints.

3. Examine Exhaust System

Sub-steps:
1. Inspect the exhaust system for loose or damaged hangers.
2. Check the muffler and pipes for any signs of rust or perforation.
3. Tighten any loose bolts or clamps securing the exhaust components.

4. Assess CV Joints and Axles

Sub-steps:
1. Inspect the CV joints for torn boots or grease leakage.
2. Check the axles for bends or cracks.
3. If damaged, replace the CV joint or axle assembly as necessary.

5. Reassemble and Lower Vehicle

Sub-steps:
