Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and secure it with wheel chocks.
Ensure you have safety gear (gloves, safety glasses).

2. Inspect and Adjust Tire Pressure

Remove valve caps from all tires.
Use a tire pressure gauge to check each tire's pressure.
Inflate or deflate tires to meet the manufacturer’s recommended pressures.

3. Check and Replace Tires (if necessary)

Remove each wheel using a socket set.
Inspect tires for damage; replace any that are worn or damaged.
If tires are in good condition, proceed to the next step.

4. Wheel Balancing

Mount the wheels onto a wheel balancer.
Spin to check for balance; adjust weights accordingly to achieve balance.
Reinstall wheels on the vehicle and torque to manufacturer specifications.

5. Wheel Alignment

Place the vehicle on an alignment rack.
Adjust toe, camber, and caster to meet manufacturer specifications.
Test drive the vehicle after adjustments.

6. Inspect Suspension Components

Visually inspect suspension parts (struts, shocks, control arms, bushings).
Replace any worn or damaged components as necessary.
