What are the steps for using a wheel alignment machine?

The steps for using a wheel alignment machine are: 1. Park the vehicle on a level surface, check if the tire pressure on both sides is equal, and install the sensors after making necessary adjustments; 2. Turn the steering wheel left and right as instructed by the computer, check the front and rear axle data, then install the brake lock to secure the steering wheel; 3. Lift the vehicle and make necessary adjustments to the front axle's toe-in, camber, and caster angles according to the computer data; 4. Inspect and adjust the toe-in of the rear axle; 5. After tightening the bolts, conduct a test drive. Wheel alignment machines include toe-in gauges, optical level alignment machines, string alignment machines, CCD alignment machines, laser alignment machines, and 3D imaging alignment machines.

I've been running an auto repair shop for over a decade and perform wheel alignments daily. The first step is to inspect the vehicle's suspension and steering system, checking for any wheel deformation or damage—this is crucial for safety and can't be taken lightly. Then, drive the car onto a specialized alignment platform and secure it firmly, ensuring the platform is level and the vehicle is stable. Next, attach the sensors—one clip per wheel—connecting them to the computer system. Lift the vehicle to suspend the wheels at the standard height for measurement. Input the car's make, model, and year into the computer, then initiate the scan to measure toe, camber, and caster angles. If deviations are found, use a wrench to adjust the corresponding nuts—take your time, don't rush, and ensure precise adjustments. After adjustments, retest several times to confirm accuracy. Once everything checks out, remove the sensors and lower the vehicle. Finally, take the car for a test drive to ensure it runs smoothly without pulling to either side. Remember, performing this service annually extends tire life, prevents uneven wear (saving you money), and significantly enhances safety—never overlook this maintenance task.

Last week I just had a wheel alignment done at the auto repair shop, and as a regular car owner, I'll briefly share my experience. The technician first checked if there were any obvious issues with my tires and suspension, then drove the car onto that large platform and parked it steadily. They attached sensors to all four wheels, and those small devices automatically detected the angles. The lift raised the car into the air, and seeing the wheels floating was quite scary but safe. After entering the car model information into the computer, they started measuring. The screen showed some deviations in the data, so they used tools to slowly adjust the toe-in by tightening nuts near the wheels. After the adjustment, they measured again to ensure everything was correct. Finally, when driving off, the steering wheel was much straighter and no longer pulled to one side. I recommend that beginners don't attempt this themselves—the equipment operation is complex and prone to errors. It's worth spending a few hundred bucks at a professional shop to avoid the hassle of premature tire replacement in the future.

As a car enthusiast with extensive experience in vehicle maintenance, I'm very familiar with the wheel alignment procedure. First, ensure the vehicle is fault-free and securely positioned on the alignment rack, then install sensors on all four wheels. Lift the car to standard height, input vehicle data into the computer to initiate initial measurements, and check if toe and camber values meet specifications. If deviations exist, immediately adjust corresponding bolts to correct angles through repeated calibration. After completion, conduct a road test – smooth driving confirms success. This process demands attention to detail, but performing it regularly prevents abnormal tire wear and enhances handling stability. It's a worthwhile investment – never skip it to save money and ensure peace of mind.
