Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and eyewear.

2. Tire Inspection

Tools Required: Tire pressure gauge, tread depth gauge
Check tire pressure and inflate to the manufacturer's recommended PSI.
Measure tire tread depth; replace tires if tread is below 2/32 inches.
Inspect for bulges or cuts on the tire sidewalls.

3. Wheel Balancing

Tools Required: Wheel balancer
Remove the wheel from the vehicle.
Mount the wheel on the wheel balancer and spin to check for imbalance.
Adjust by adding or removing wheel weights as necessary.

4. Suspension and Steering Inspection

Tools Required: Jack and jack stands, socket set
Raise the vehicle using a jack and secure it with jack stands.
Inspect all suspension components (shocks, struts, control arms) for wear or damage.
Check for any movement in the steering components (tie rods, ball joints).

5. Alignment Adjustment

Tools Required: Alignment tool
Perform a four-wheel alignment check.
Adjust camber, caster, and toe settings to align with manufacturer specifications.

6. Reassembly

Reinstall the wheel and torque lug nuts to the specified torque (usually 76-87 ft-lbs for most Toyota vehicles).
Lower the vehicle and perform a test drive to check for vibrations.
