Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, flashlight.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported before working underneath.

2. Inspect and Replace Suspension Components

Sub-steps:
1. Use a jack to lift the vehicle and secure it with jack stands.
2. Remove the front wheels to gain access to the suspension components.
3. Visually inspect struts, shocks, bushings, and control arms for signs of wear, cracking, or damage.
4. If any component is found to be defective, remove it using the socket set and replace it with a new part.
5. Reassemble any removed components and reinstall the wheels.

3. Tighten Suspension Bolts

Sub-steps:
1. With the vehicle still lifted, use the torque wrench to check and tighten all suspension-related bolts to the manufacturer’s specified torque settings.
2. Ensure that all components are secure and properly aligned.

4. Inspect and Replace CV Joints and Axles (if necessary)

Sub-steps:
1. Inspect CV joints for any cracks or torn boots.
2. If damage is found, remove the axle assembly using a socket set.
3. Replace the CV joint or axle with a new one, ensuring proper installation.
4. Reinstall the axle and secure it with the appropriate torque.

5. Check Exhaust System Mounts
