Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Safety warning: Ensure the vehicle is secure on jack stands before working underneath.

2. Tire Inspection and Maintenance

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Check tire pressure using a tire pressure gauge and inflate to the manufacturer's specifications.
3. Inspect tires for any visible damage such as cuts, bulges, or uneven tread wear.
4. Rotate tires if uneven wear is noted.

3. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a socket set.
2. Take the wheels to a tire shop for professional balancing.
3. Reinstall balanced wheels to the vehicle, ensuring proper torque specifications (typically 80-100 ft-lbs for XC90, but verify with the owner's manual).

4. Wheel Alignment

Sub-steps:
1. After balancing, perform a four-wheel alignment using an alignment machine.
2. Adjust the camber, caster, and toe settings to meet factory specifications.
3. Test drive the vehicle to confirm alignment correction.

5. Suspension and Drivetrain Inspection

Sub-steps:
1. Visually inspect all suspension components for signs of wear or damage.
2. Check for loose or damaged control arms, bushings, and shock absorbers.
3. Inspect the driveshaft and CV joints; replace any components that show signs of wear or imbalance.
