Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues during inspection.

2. Inspect Drivetrain Components

Sub-steps:
- Raise the vehicle using a jack and secure with jack stands.
- Visually inspect the driveshaft and axles for cracks or wear.
- Check the differential fluid level and condition; replace if necessary.

3. Examine Suspension System

Sub-steps:
- Inspect control arms, bushings, and ball joints for signs of wear.
- Replace any worn or damaged suspension components with OEM parts.
- Ensure all bolts and nuts are torqued to manufacturer specifications.

4. Exhaust System Check

Sub-steps:
- Inspect the entire exhaust system from the manifold to the tailpipe.
- Look for signs of rust, holes, or loose connections; replace any damaged sections.
- Tighten any loose clamps or hangers.
