Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is turned off.
Gather all necessary tools and parts before starting the repair.
Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, stethoscope.

2. Inspect and Replace Suspension Components

Inspect Control Arms and Bushings
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the wheel to gain access to the suspension.
- Inspect control arms and bushings for cracks or excessive wear.
- If damaged, remove the bolts securing the control arm using the socket set.
- Replace with new control arms and bushings, tightening to the manufacturer’s torque specifications (usually around 60-80 ft-lbs).

3. Check and Replace Struts/Shocks

Inspect Struts for Leaks
- Check for oil leaks around the strut bodies.
- If leaking, remove the strut assembly by unbolting it from the top mount and lower control arm.
- Replace with new struts, ensuring proper alignment of the mounting holes.
- Torque bolts to specifications (typically around 30-40 ft-lbs).

4. Inspect and Tighten/Replace Exhaust Components

Check Exhaust System
- Inspect exhaust hangers and brackets for damage or looseness.
- Tighten any loose bolts or replace broken hangers as needed.

5. Final Assembly and Lower Vehicle

Reinstall the wheel and lower the vehicle from the jack stands.
Perform a final inspection to ensure all components are securely fastened.
