Solution

1. Preparation

Gather tools and parts needed for inspection and repair.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery for safety if working on electrical components.

2. Inspect and Repair Suspension Components

Lift Vehicle: Use a jack and jack stands to raise the vehicle safely.
Remove Wheel: Take off the wheel on the side where the noise is most prominent.
Inspect Components:
- Check control arms, struts, and bushings for any signs of wear or damage.
- Replace any cracked or broken components.
- Torque specifications for control arm bolts should be followed (typically around 50-70 ft-lbs, check manufacturer specifications).
Reassemble:
- Reinstall the wheel and lower the vehicle.
- Tighten lug nuts to the specified torque (typically 80-100 ft-lbs).

3. Inspect and Repair Exhaust System

Visual Inspection: Look for loose hangers, damaged pipes, or holes in the exhaust system.
Tighten Connections: Use a wrench to tighten any loose bolts or clamps in the exhaust.
Replace Components: If necessary, replace any damaged sections of the exhaust system, ensuring proper fitment.
Check for Leaks: After repairs, start the engine and listen for leaks in the exhaust system.
