Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Tire Inspection and Adjustment

Use a tire pressure gauge to check the pressure of all tires.
Inflate tires to the manufacturer's recommended PSI if necessary.
Inspect tires for uneven wear, bulges, or damage; replace any defective tires.

3. Wheel Alignment and Balancing

Take the vehicle to a professional alignment shop.
Request a four-wheel alignment and balance service.
Ensure the alignment settings are within the manufacturer's specifications.

4. Suspension Inspection

Lift the vehicle using a jack and secure it with jack stands.
Visually inspect all suspension components for signs of wear or damage.
Replace any worn components, such as shocks or struts, following the manufacturer's guidelines.

5. Final Check and Reassembly

Re-torque all lug nuts to the manufacturer’s specified torque values (typically 85 ft-lbs for Tacoma).
Lower the vehicle and perform a final inspection of all work done.
Test drive the vehicle to ensure stability has improved.
