Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, torque wrench, wheel alignment tool, and balancing machine.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Tire Inspection and Replacement

Inspect Tires:
- Remove the hubcaps if equipped.
- Check each tire for uneven wear, damage, or foreign objects.
Replace Tires (if necessary):
- If tires are worn or damaged, replace with high-quality tires that match OEM specifications.
- Mount and balance new tires following the manufacturer's instructions.

3. Wheel Balancing

Balance Wheels:
- Remove each wheel from the vehicle.
- Mount the wheel on the balancing machine and spin to detect imbalance.
- Add wheel weights as needed to ensure proper balance.
- Reinstall wheels, tightening lug nuts to the manufacturer's torque specifications (typically 76 ft-lbs for Tacoma).

4. Wheel Alignment

Perform Alignment:
- Place the vehicle on an alignment rack.
- Adjust the camber, caster, and toe settings to match OEM specifications.
- Confirm alignment is within specifications for both front and rear axles.

5. Drivetrain Inspection

Inspect Driveshaft and U-joints:
- Raise the vehicle and secure it on jack stands.
- Inspect the driveshaft for any signs of wear or damage.
- Check U-joints for play or binding; replace if necessary.
