Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Make sure the engine is off and keys are removed from the ignition.

2. Tire Balancing

Tools Required: Wheel balancer, jack, jack stands
Lift the vehicle using a jack and secure it with jack stands.
Remove the front wheels using a socket set.
Mount each wheel on a wheel balancer and check for imbalances.
Attach wheel weights as needed to balance the wheels properly.

3. Tire Inspection

Inspect each tire for any visible damage or uneven wear.
Check air pressure and inflate to manufacturer's recommended PSI if necessary.
Replace any tires that are excessively worn or damaged.

4. Wheel Alignment

Tools Required: Alignment machine
Adjust the wheel alignment according to the manufacturer's specifications.
Ensure that camber, toe, and caster settings are within the recommended ranges.

5. Suspension Inspection

Inspect all suspension components visually and physically for play or damage.
Replace any worn or damaged components, such as tie rods or control arms.

6. Lug Nut Torque Check

Use a torque wrench to ensure that lug nuts are tightened to the specified torque (typically around 76 ft-lbs for Toyota Highlander).
Reinstall wheels and ensure they are secured properly.
