Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, torque wrench, tire pressure gauge.
Safety Warnings: Ensure the vehicle is parked on a flat surface and set the parking brake. Allow the engine to cool before working on it.

2. Tire Inspection and Balancing

Check Tire Pressure:
- Use a tire pressure gauge to measure the pressure of all four tires.
- Inflate to the manufacturer's recommended PSI if needed.
Inspect Tire Tread:
- Examine the tires for uneven wear or damage; replace if necessary.
Balance Tires:
- Remove the tires using a jack and socket set.
- Take tires to a professional for balancing, or use a balance machine if available.

3. Driveshaft and Axle Inspection

Visual Inspection:
- Check the driveshaft and axles for visible damage, such as dents or cracks.
Check for Play:
- Wiggle the driveshaft and axles to check for excessive movement; replace components if they are loose.

4. Engine and Transmission Mounts

Visual Inspection:
- Inspect engine and transmission mounts for cracks or deterioration.
Replace Worn Mounts:
- If mounts are damaged, remove the old mounts and install new ones, ensuring they are torqued to manufacturer's specifications.
