Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Raise the vehicle using a jack and secure it with jack stands.

2. Inspect Suspension Components

Tools Required: Socket set, torque wrench, pry bar
Remove the wheels for better access.
Check the condition of the struts and shocks for leakage or damage.
Inspect control arm bushings and sway bar links for signs of wear.
Use a pry bar to manipulate suspension components and check for play or excessive movement.
Replace any worn or damaged components as needed.

3. Examine Exhaust System

Tools Required: Wrench set
Inspect the exhaust hangers and brackets for looseness or damage.
Tighten any loose bolts or replace damaged hangers.
Check for any contact points between the exhaust and the chassis that might cause rattling.
