Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and safely secured with wheel chocks.
Tools Required: Jack, jack stands, torque wrench, tire pressure gauge, OBD-II scanner.

2. Tire Balancing

Remove the wheel and tire assembly from the vehicle using a jack.
Place the tire on a balancing machine and spin it to check for imbalances.
If imbalances are found, add weights as needed and recheck until balanced.
Reinstall the wheel on the vehicle and torque to manufacturer specifications (usually around 76-83 ft-lbs for most Toyota models).

3. Wheel Alignment

Use an alignment machine to check the vehicle's alignment specifications.
Adjust the camber, caster, and toe angles to match manufacturer specifications.
After adjustment, test drive the vehicle to ensure alignment is correct.

4. Suspension Component Inspection

Inspect rubber bushings, ball joints, and control arms for any signs of wear.
Replace any damaged components as necessary.
Use a torque wrench to ensure all bolts are tightened to the recommended specifications.

5. Final Check

After all repairs, take the vehicle for a test drive to ensure vibrations are resolved.
Monitor the steering feel and vehicle stability at high speeds.
