If you feel a difference in the way you’re driving your car, getting the laser wheel alignment done from a mobile car mechanic might hold the solution.

A four-wheel laser alignment test on your car can help you expose all the geometries of your steering and suspension. With this blog, you can learn what is done and why it must be done?

While driving your car, did you notice uneven tire wear?

Was the handling soggy?

Was the steering tugging to one side? or

Was the steering wheel not centring itself when your car was moving in a straight line?

The above problems can be fixed with a four-wheel laser alignment check. It can identify the issues and can also display it on-screen. The mechanic can make the required precise adjustments and get the properly aligned vehicle on-road.

What does a four-wheel alignment do?

Within the four-wheel alignment, 12 angles are measured, which are then compared with the data provided by the vehicle manufacturer or OEMs.

With laser wheel alignment, it’s easier for the mechanic to ...

The theory behind the four-wheel laser alignment is not rocket science. Four precision digital cameras are fixed in the aligner tower to measure the exact position and orientation of reflective targets. These are mounted to all four wheels.

The computer within the machine takes the data to calculate the car’s alignment further and then compare these measurements to the original equipment manufacturer (OEM) specifications. Although most data are massive and might include an extensive range of cars from the 60s, 70s, and 80. In such cases, the information can be input manually. Most of these details about the car model are individually available in the original manufacturer’s handbook.

When the computer reveals the geometry of the alignments, the mechanic can then cross-refer to on-screen information to make the required adjustments to all the four wheels and position them straight and parallel, making the steering wheel centred.

This is the only procedure followed during a laser wheel alignment. It takes only a few minutes from the time the clamps are fitted, and the vehicle’s vital statistics are tapped into the computer.

Why must you get a wheel alignment done?

In the automobile sector, it’s one of the best ways to guarantee the proper alignment of four wheels. If you’re getting some auto parts replaced, then wheel alignment is the only way to reset the car’s geometry accurately. Once the new parts are fitted, and the essential factory settings are retrieved from the database, the check must be carried out, and the necessary adjustments can be made to get the alignment spot on.
