Solution

1. Preparation

Tools Required: Jack, jack stands, torque wrench, tire pressure gauge, diagnostic scanner.
Ensure the vehicle is on a flat surface and the engine is off.
Wear safety glasses and gloves.

2. Wheel and Tire Inspection

Sub-steps:
1. Use a jack to lift the vehicle and secure it with jack stands.
2. Remove the wheel covers or hubcaps if applicable.
3. Inspect each tire for bulges, cracks, or embedded objects.
4. Check for proper tire pressure using a tire pressure gauge.
5. If tires are damaged or significantly worn, replace them.

3. Suspension and Drivetrain Inspection

Sub-steps:
1. Visually inspect all suspension components (control arms, bushings, struts) for signs of wear.
2. Check the driveshaft and CV joints for any tears in the rubber boots or looseness.
3. If any components are damaged, replace them accordingly.

4. Balancing and Alignment (if needed)

Sub-steps:
1. If tires are in good condition, take them to a tire shop for balancing.
2. Request a wheel alignment if the vehicle is pulling to one side.
3. Verify that all bolts are torqued to manufacturer specifications after reinstalling wheels.

5. Error Code Analysis
