Solution

1. Tire Inspection and Maintenance

Sub-steps:
- Visually inspect all tires for bulges, cracks, or uneven wear.
- Use a tire pressure gauge to check the inflation of each tire; adjust to manufacturer specifications (usually around 32-35 psi).
- If tires are worn unevenly, rotate them as needed or replace them if they are beyond usable limits.

2. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using a socket set.
- Take the wheels to a tire shop for professional balancing.
- Reinstall the wheels and torque lug nuts to manufacturer specifications (typically around 76 ft-lbs).

3. Suspension Inspection and Repair

Sub-steps:
- Visually inspect shocks, struts, and bushings for any signs of wear or leaks.
- If any components are damaged, replace them with OEM or high-quality aftermarket parts.
- Reassemble the suspension components and ensure all hardware is torqued correctly.

4. Wheel Alignment

Sub-steps:
- After addressing any suspension issues, take the Tacoma to a professional for a four-wheel alignment.
- Ensure that the alignment specifications meet manufacturer standards.

5. Drivetrain Inspection

Sub-steps:
- Inspect the driveshaft and axles for any visible signs of damage or play.
- If any components are found to be loose or damaged, replace them as necessary.
