Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, OBD-II scanner, torque wrench, tire balancing machine.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Tire Inspection and Balancing

Sub-steps:
1. Remove the wheel using the lug wrench.
2. Inspect the tire tread for uneven wear patterns.
3. If the tires are unbalanced, mount them on a tire balancing machine and adjust as necessary.
4. Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (usually around 80 ft-lbs for Tacoma).

3. Driveshaft Inspection

Sub-steps:
1. Safely raise the vehicle and support it with jack stands.
2. Inspect the driveshaft for signs of damage or excessive play.
3. Check the U-joints for smooth rotation and no binding; replace if damaged.
4. Reinstall the driveshaft and ensure all bolts are torqued to specifications.

4. Engine and Transmission Mount Inspection

Sub-steps:
