Solution

1. Preparation

Tools Needed: Jack and jack stands, tire iron, torque wrench, OBD-II scanner, multimeter.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Tire Inspection

Sub-steps:
1. Remove the wheel covers if applicable.
2. Use the tire iron to loosen the lug nuts slightly (do not remove).
3. Raise the vehicle using a jack and secure it with jack stands.
4. Remove the wheels and inspect for uneven wear patterns or damage.
5. Check air pressure in all tires and adjust as necessary.

3. Driveline Component Check

Sub-steps:
1. Inspect the driveshaft for any signs of damage, such as dents or bends.
2. Examine the CV joints for any leaks or torn boots.
3. Rotate the driveshaft by hand to ensure it spins freely without binding.

4. Engine and Transmission Mount Inspection

Sub-steps:
1. Locate the engine and transmission mounts (typically found at the rear of the engine and under the transmission).
2. Visually inspect for cracks, tears, or significant wear.
3. Use a pry bar to gently test the movement of the mounts; excessive movement may indicate the need for replacement.

5. Wheel Alignment and Balancing

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Request a wheel balance check and alignment service.
3. Ensure that the technician performs a road test to verify results.
