Solution

1. Tire Inspection and Maintenance

Sub-steps:
- Check tire pressure using a tire pressure gauge and inflate to manufacturer specifications.
- Inspect tires for uneven wear patterns; replace if necessary.
- Rotate tires if uneven wear is detected to ensure balanced wear.

2. Drivetrain Component Inspection

Sub-steps:
- Raise the vehicle using a jack and secure it with jack stands.
- Inspect the driveshaft for any visible damage or excessive play in the universal joints.
- Tighten any loose bolts on the driveshaft and replace any damaged universal joints.

3. Engine and Transmission Mount Replacement

Sub-steps:
- Disconnect the negative battery terminal to prevent electrical shorts.
- Remove any components obstructing access to the engine and transmission mounts.
- Unbolt and remove the damaged mounts.
- Install new mounts and torque to manufacturer specifications.

4. Suspension Component Inspection

Sub-steps:
- Visually inspect shock absorbers, struts, control arms, and bushings for wear or damage.
- Replace any worn suspension components as needed.
- Ensure all bolts are tightened to the manufacturer’s torque specifications.
