Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and disconnect the battery for safety.

2. Tire Inspection and Replacement

Inspect Tires:
- Check tire pressure and inflate to manufacturer specifications.
- Examine tread depth and surface for damage.
Replace Tires (if needed):
- Remove lug nuts using a socket set and take off the wheel.
- Install new tire and torque lug nuts to the manufacturer’s specification (often 80-100 ft-lbs).
- Repeat for each affected tire.

3. Wheel Balancing

Wheel Balance:
- Remove the wheel from the vehicle.
- Mount the wheel on a tire balance machine.
- Follow the machine instructions to balance the wheel and add weights as required.

4. Driveshaft and CV Joint Inspection

Inspect Driveshaft:
- Lift the vehicle using jack stands.
- Visually inspect the driveshaft for any cracks or play in the joints.
- Replace any damaged components (if necessary).

5. Engine and Transmission Mounts

Inspect and Replace Mounts:
- Locate the engine and transmission mounts.
- Check for cracks or excessive wear.
- If damaged, remove the old mount using a socket set, and install the new mount, torquing to specification.
