Solution

1. Preparation

Gather tools and safety equipment, including gloves and safety glasses.
Ensure the vehicle is parked on a flat, stable surface and engage the parking brake.

2. Tire Inspection

Tools Required: Tire pressure gauge, flashlight
Check each tire for visible damage, such as cuts or bulges.
Use a tire pressure gauge to ensure all tires are inflated to the manufacturer’s recommended pressure.
If tires are unevenly worn, consider rotating or replacing them as necessary.

3. Wheel Bearing Inspection

Tools Required: Jack, jack stands, torque wrench
Raise the vehicle with a jack and secure it on jack stands.
Grasp each wheel at the 12 o'clock and 6 o'clock positions and shake it to check for play.
If there is movement, the wheel bearing may need to be replaced.

4. Suspension Component Inspection

Tools Required: Socket set, wrench set
Inspect struts and shocks for leaks or physical damage.
Check control arm bushings and other rubber components for wear, cracking, or deterioration.
Replace any damaged components as needed.

5. Driveshaft and CV Joint Inspection

Tools Required: Socket set, pry bar
Inspect the driveshaft for dents, bends, or loose connections.
Check CV joints for any torn boots or excessive play.
Replace any faulty components before reassembly.

6. Exhaust System Inspection

Tools Required: Wrench set, flashlight
Inspect the exhaust system for any loose brackets or hangers.
Ensure the exhaust does not make contact with any other components.
Tighten or replace any loose parts as necessary.
