Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Inspect and Replace Tires

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Loosen the lug nuts with a socket wrench and remove the wheel.
3. Inspect the tire for uneven wear or damage; consider replacing if necessary.
4. Balance the tires if they are in good condition.
5. Reinstall the wheel and torque the lug nuts to manufacturer specifications (typically 80-100 lb-ft).

3. Check and Replace Drivetrain Components

Sub-steps:
1. Visually inspect the driveshaft and axles for any signs of wear, such as torn boots or damaged joints.
2. If damage is found, remove the affected component:
  - For driveshaft: Disconnect the bolts at both ends and remove it.
  - For axles: Remove the axle nut and disconnect from the hub.
3. Replace the damaged component with a new one, following proper torque specifications.
4. Reconnect all components securely.

4. Inspect and Replace Engine/Transmission Mounts

Sub-steps:
1. Open the hood and locate the engine mounts.
2. Use a jack to support the engine gently.
3. Remove the bolts securing the mounts to the engine and frame.
4. Replace any worn or damaged mounts with new ones.
5. Reinstall and torque the bolts to manufacturer specifications.
