Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the emergency brake is engaged.
Disconnect the battery if working on electrical components.

2. Tire Inspection

Sub-steps:
- Check tire pressure with a gauge; adjust to manufacturer specifications.
- Inspect tires for uneven wear patterns or bulges; replace if necessary.
- Rotate tires if uneven wear is noted to ensure even distribution.

3. Wheel Balancing

Sub-steps:
- Remove the wheel from the vehicle using a socket set.
- Take the wheel to a tire shop for professional balancing.
- Reinstall the wheel after balancing, ensuring proper torque values (typically 80-100 ft-lbs for Volvo XC90).

4. Suspension Inspection

Sub-steps:
- Visually inspect struts and shocks for leaks or damage.
- Check all suspension bushings for cracks or deterioration.
- Replace worn components as necessary, following manufacturer guidelines.

5. Wheel Alignment

Sub-steps:
- After suspension inspection, use an alignment machine to check wheel alignment.
- Adjust camber, caster, and toe settings as per manufacturer specifications.
- Test drive the vehicle to ensure that the alignment has resolved any pulling or vibration issues.
