Solution

1. Preparation

Gather tools: socket set, torque wrench, jack and jack stands, and a pry bar.
Park the vehicle on a level surface and engage the parking brake.
Allow the vehicle to cool if it has been running.

2. Inspect and Replace Suspension Components

Inspect Shocks/Struts:
- Use a jack to lift the front and/or rear of the vehicle.
- Remove the wheels to gain access to the suspension.
- Check for oil leakage around the shocks or struts.
- If leakage is present, replace the affected shocks or struts.
Replace Bushings:
- Use a pry bar to check the condition of control arm bushings.
- If they are cracked or deteriorated, remove the control arms and replace the bushings.
Tighten Loose Hardware:
- Inspect all suspension bolts and nuts.
- Tighten any loose fasteners to the manufacturer’s torque specifications.

3. Inspect and Repair Exhaust System

Examine the exhaust hangers and mounts for damage.
Replace any broken or missing hangers to prevent rattling.

4. Check Wheel Bearings

Spin the wheel and listen for grinding noises.
If the bearings feel loose, remove the wheel and hub assembly.
Replace any worn or damaged wheel bearings.
