Solution

1. Preparation

Tools Required: Floor jack, jack stands, tire pressure gauge, OBD-II scanner, torque wrench, alignment machine.
Raise the vehicle on a flat surface using a floor jack and secure it with jack stands.
Ensure the vehicle is in “Park” mode and the parking brake is engaged.

2. Tire Inspection and Adjustment

Sub-steps:
1. Remove the wheel covers or lug nut caps if applicable.
2. Check tire pressure and inflate to the manufacturer’s recommended PSI.
3. Inspect tires for uneven wear, bulges, or damage; replace if necessary.
4. If tires are worn, consider rotating or replacing them.

3. Wheel Alignment and Balancing

Sub-steps:
1. Mount the vehicle on an alignment rack.
2. Check alignment settings against manufacturer specifications.
3. Adjust the alignment as needed to bring it back within specifications.
4. Balance the wheels using a wheel balancing machine if vibrations persist.

4. Suspension Component Inspection

Sub-steps:
1. Visually inspect control arms, ball joints, and bushings for wear or damage.
2. Replace any worn or damaged components.
3. Tighten all suspension bolts to the manufacturer's torque specifications.

5. Driveshaft and CV Joint Inspection

Sub-steps:
1. Inspect the driveshaft for any signs of damage or unusual wear.
2. Check CV joints for play and ensure they are properly lubricated.
3. Replace any faulty driveshaft or CV joint components if necessary.
