Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a flat, stable surface.
Use wheel chocks to secure the vehicle and raise the front of the vehicle with a jack.

2. Inspect and Adjust Tire Pressure

Sub-steps:
- Remove tire valve caps and use a tire pressure gauge to check the pressure.
- Inflate or deflate tires to the recommended pressure found in the owner’s manual or on the door jamb sticker.
- Visually inspect tires for bulges, cuts, or irregular wear.
Tools Required: Tire pressure gauge, air compressor.

3. Balance the Wheels

Sub-steps:
- Remove the wheels from the vehicle.
- Mount wheels on a wheel balancer to check for imbalances.
- Add wheel weights as needed to balance each wheel properly.
Tools Required: Wheel balancer, wheel weights, lug nut wrench.

4. Inspect Suspension Components

Sub-steps:
- Check the condition of shocks and struts for leaks or damage.
- Inspect control arms, tie rods, and sway bar links for signs of wear.
- Replace any worn or damaged components.
Tools Required: Jack stands, socket set, torque wrench.

5. Perform Wheel Alignment

Sub-steps:
- Use an alignment machine to measure the angles of the wheels.
- Adjust the camber, caster, and toe angles to manufacturer specifications.
- Test drive the vehicle to ensure alignment is correct.
Tools Required: Wheel alignment machine, wrench set.
