Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety warning: Raise the vehicle using jack stands, ensuring it is secured before working underneath.

2. Tire Inspection and Replacement

Check each tire for bulges, cracks, or uneven wear.
If any tires are damaged, remove them using a socket set.
Replace damaged tires with new ones, ensuring they meet the specifications for the XC90.
Inflate tires to the recommended PSI.

3. Wheel Balancing

Remove the wheels from the vehicle using a socket set.
Mount the wheels on a wheel balancer to check for balance.
If imbalances are found, add wheel weights as needed to correct them.
Reinstall the balanced wheels onto the vehicle, tightening the lug nuts to the manufacturer's torque specifications (typically around 100-110 ft-lbs).

4. Suspension Inspection and Repair

Inspect all suspension components for wear or damage.
Replace any worn control arms, bushings, or other components as necessary.
Reassemble and tighten all components according to manufacturer specifications.

5. Driveshaft and CV Joint Check

Inspect the driveshaft and CV joints for any play or wear.
Replace any damaged parts to prevent further vibration issues.
Ensure all fasteners are torqued to specifications.
