Sub-steps:
- Raise the vehicle using a jack and secure it with jack stands.
- Inspect the drive shafts and axles for any visible damage or looseness.
- Tighten any loose bolts on the drive components to the manufacturer's specified torque values.

3. Check and Replace Motor Mounts (if needed)

Sub-steps:
- Remove any covers or shields obstructing access to motor mounts.
- Use a wrench to unbolt the motor mounts from the engine and chassis.
- Replace with new motor mounts if they show signs of wear or failure.
- Reinstall the bolts and torque to the manufacturer's specifications.

4. Inspect and Replace Suspension Components (if necessary)

Sub-steps:
- Check control arms and bushings for wear; replace if damaged.
- Remove any worn components and install new parts, ensuring proper alignment and torque specifications.
- Reinstall wheels and lower the vehicle to the ground.

5. Final Assembly

Reconnect the battery and start the vehicle.
Ensure all components are secured and properly installed.
