Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on electronic components.

2. Tire Inspection

Remove the wheel covers or hubcaps if applicable.
Inspect each tire for signs of damage, uneven wear patterns, or bulges.
If any damage is found, replace the affected tire.

3. Wheel Balancing

Mount the tires on a balancing machine.
Adjust weights accordingly to achieve balance.
Reinstall the tires on the vehicle, ensuring proper torque specifications (typically 76-80 ft-lbs for Toyota).

4. Wheel Alignment

Set the vehicle on an alignment rack.
Adjust the camber, caster, and toe settings to align with manufacturer's specifications.
Confirm alignment by checking the printout from the alignment machine.

5. Suspension Inspection and Repair (if necessary)

Visually inspect tie rods, ball joints, and control arms for play or damage.
Replace any worn components as necessary.
