Solution

1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, torque wrench, alignment tool, OBD-II scanner.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Loosen the lug nuts on all four wheels using a lug wrench.
3. Lift the vehicle using the jack and secure it with jack stands.
4. Remove the wheels and inspect each tire for uneven wear or damage.
5. If necessary, replace tires with new ones that meet manufacturer specifications (e.g., size, load rating).
6. Reinstall wheels and torque lug nuts to the manufacturer’s specifications (usually 80-100 ft-lbs).

3. Wheel Alignment Adjustment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Ensure that the alignment is adjusted according to the manufacturer's specifications.
3. Perform a test drive to check for improvement in handling and skipping sensation.

4. Drivetrain Inspection and Repair

Sub-steps:
1. Inspect the driveshaft for any signs of damage or excessive play.
2. Check the CV joints for wear; replace if necessary.
3. If any issues are found, replace the driveshaft or CV joints as needed.
4. Verify all connections and mounts are secure.

5. Brake System Check
