Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Wear safety gloves and goggles for protection.

2. Tire Inspection and Rotation

Sub-steps:
- Use a tire pressure gauge to check each tire's pressure and inflate to the manufacturer's specifications if necessary.
- Inspect tires for uneven wear patterns or visible damage.
- Rotate the tires if uneven wear is detected, following the correct rotation pattern for your vehicle.
Tools Required: Tire pressure gauge, floor jack, jack stands, lug wrench.

3. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using the lug wrench.
- Take the wheels to a tire shop for balancing or use a wheel balancer if available.
- Reinstall the wheels after balancing, ensuring lug nuts are torqued to the manufacturer’s specifications (typically 70-80 ft-lbs for Toyota).
Tools Required: Lug wrench, torque wrench.

4. Suspension Component Inspection

Sub-steps:
- Lift the vehicle using a floor jack and secure it with jack stands.
- Visually inspect all suspension components for wear, such as control arms, bushings, and shocks/struts.
- Replace any worn or damaged components.
Tools Required: Floor jack, jack stands, socket set.

5. Driveshaft and CV Joint Inspection

Sub-steps:
- Inspect the driveshaft for any signs of damage or excessive play.
- Check CV joints for wear or damage, looking for cracks in the rubber boots.
- Replace any faulty driveshafts or CV joints as needed.
Tools Required: Socket set, pry bar.
