Solution

1. Preparation

Gather tools: Jack and jack stands, tire pressure gauge, torque wrench, wheel balancer, alignment machine.
Park the vehicle on a level surface and engage the parking brake.

2. Tire Inspection and Repair

Check Tire Pressure:
- Use a tire pressure gauge to ensure all tires are inflated to the manufacturer’s specifications (found in the owner’s manual or on the driver’s door jamb).
- Inflate any under-inflated tires to the correct pressure.
Inspect Tires for Damage:
- Visually inspect each tire for bulges, cuts, or foreign objects.
- Replace any damaged tires if necessary.
Balance Wheels:
- Remove the wheels using a lug wrench and place them on a wheel balancer.
- Adjust weights as needed to achieve balance.
- Reinstall the wheels and torque to the manufacturer’s specifications (typically around 76 lb-ft for Tacoma).

3. Suspension and Alignment Check

Inspect Suspension Components:
- Check shocks and struts for leaks or damage.
- Inspect control arms and bushings for wear; replace any worn components.
Perform Wheel Alignment:
- Align the vehicle using an alignment machine, ensuring that all angles are within specifications for the Tacoma.
- Adjust as necessary to correct any misalignment.

4. Driveline Inspection

Inspect Driveshaft and CV Joints:
- Check the driveshaft for any signs of bending, damage, or excessive play.
- Inspect CV joints for torn boots or grease leaks. Replace if necessary.
