Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Adjust Tire Pressure

Sub-steps:
1. Remove valve caps from each tire.
2. Use a tire pressure gauge to measure the tire pressure.
3. Inflate or deflate each tire to the recommended pressure noted in the owner’s manual (typically around 32-35 PSI for the XC90).
4. Replace valve caps securely.

3. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Use alignment equipment to adjust the camber, caster, and toe angles according to manufacturer specifications.
3. Confirm that all adjustments are within specified tolerances.

4. Inspect and Replace Suspension Components

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Remove the front wheels using a socket set.
3. Inspect struts and shocks for leaks or wear; replace if necessary.
4. Check control arms and bushings for cracks or excessive play; replace as needed.
5. Reassemble components and lower the vehicle.

5. Rotate Tires

Sub-steps:
1. Remove the wheels again after the alignment and suspension checks.
2. Rotate tires according to the recommended pattern (e.g., front to back, side to side) to promote even wear.
3. Reinstall the wheels and torque the lug nuts to the recommended specification (typically 80-100 ft-lbs).
