Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Tire Inspection and Replacement

Inspect Tires:
- Check for uneven wear patterns, bulges, or punctures.
- Measure tire tread depth; replace if below 2/32 inches.
Replace Tires (if necessary):
1. Loosen lug nuts with a socket set.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the wheel and replace with a new tire, ensuring it’s correctly seated.
4. Tighten lug nuts to manufacturer specifications using a torque wrench (typically 80-100 ft-lbs for XC90).

3. Wheel Balancing

Remove the wheel from the vehicle.
Mount the wheel on a wheel balancer and follow the manufacturer's instructions to balance the wheel.
Reinstall the wheel on the vehicle.

4. Suspension Component Inspection and Replacement

Inspect and Replace Worn Components:
1. Check control arms, bushings, and shocks for excessive play or wear.
2. If any components are worn, remove and replace them using a socket set.
  - Use manufacturer-recommended parts for replacement.
3. Reassemble and tighten all components to manufacturer specifications.

5. Driveshaft and CV Joint Inspection

Check the driveshaft for any signs of damage or excessive play.
Inspect CV joints for torn boots or grease leakage.
Replace the driveshaft or CV joints if any issues are found:
- Remove the retaining clips and bolts securing the driveshaft.
- Replace the component and reassemble, ensuring proper torque values are followed.
