Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Suspension Components

Inspect Control Arms and Bushings
- Remove the wheel to access the suspension.
- Check for any cracks or excessive wear on control arms and bushings.
Replace as Necessary
- If damaged, remove the old control arms using a socket set.
- Install new control arms and torque to manufacturer specifications (usually around 50-70 ft-lbs).

3. Inspect and Repair Exhaust System

Check Exhaust Components
- Inspect the exhaust manifold, catalytic converter, and exhaust pipes for loose connections or damage.
- Tighten any loose bolts or replace damaged parts.
Replace Exhaust Hangers
- If hangers are worn, remove the old hangers and install new ones to secure the exhaust system properly.

4. Inspect and Repair Drivetrain

Examine CV Joints and Axles
- Check for torn CV boots and excessive play in the CV joints.
- Replace any defective CV joints or axles by removing the wheel, disconnecting the axle nut, and replacing the component.
Reassemble and Torque
- Reassemble components and ensure all nuts and bolts are torqued to specifications (usually around 100 ft-lbs for axle nuts).
