Correct the direction of the car?

Hello, does anyone know how the car's direction can be corrected manually? I have thought about marking the position of the zipper of the address, and then loosening it and moving it a few millimeters to one side or another, I have tested the car that does notice improvement.
Why measure if the address is centered is nonsense if I can't measure the fall? Thanks for the help in advance

For the correct adjustment of the address you must take into account a series of parameters such as attack angles, fall and progress, which cannot be visualized "by eye".

It is not worth doing yourself. This is one of the issues that require the intervention of a professional. Especially because electronic tools that are not available to anyone are required.

By around € 40 a professional leaves you the address correctly regulated in addition to "making you a parallel" and a balanced.

Pay attention to me: Forget about doing so, in the end you will earn money in tires and especially in security.

A cordial greeting

I agree with exactly the colleague Zulu, it is not worth touching management levels because we talk about millimeters in things very difficult to measure if it is not machine.

The only thing you could do "by hand" would be entitled by the steering wheel with respect to the wheels and only in the case of having dismantled it for some reason, (change of steering wheel, intermittence controls or similar)

but I insist you do not touch the address levels.

All the best.
