Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, mechanic's stethoscope.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Suspension Components

Lift the Vehicle:
- Use a jack to raise the vehicle and secure it on jack stands for safety.
Remove Wheels:
- Use a socket set to remove the lug nuts and take off the wheels for easier access to suspension components.
Inspect Shocks/Struts:
- Check for leaks, dents, or corrosion. If damaged, remove them using a socket set and replace with new units.
Examine Bushings and Mounts:
- Look for cracked or worn bushings. Replace any that show signs of wear with new bushings, ensuring proper alignment.
Check Control Arms:
- Inspect control arms for play or damage. If faulty, replace them following the manufacturer’s specifications.
Reassemble:
- Reattach the wheels and torque the lug nuts to the manufacturer’s specifications. Lower the vehicle.

3. Inspect Braking System

Check Brake Components:
- Inspect brake pads and rotors for wear. Replace if necessary.
Ensure Proper Fit:
- Make sure all brake hardware is secure and free of debris.
