Today, any service station offers wheel alignment adjustment. However, car owners can carry out this procedure on their own. So they will learn to better understand and feel their car.

At a service station or on your own?

Auto mechanics unanimously claim that it is extremely difficult to set up a wheel alignment on your own. Actually it is not. Also, do not trust too much specialists from the service station, who say that these parameters in the car are violated. In car services, they offer to install the car on a wheel alignment stand and, based on the testimony of this device, perform professional tuning. In this case, do not rely on professionalism. Now there are fewer and fewer truly qualified specialists. But still, there are masters who can do this work with high quality.

Without the help of stands, they can perform an accurate diagnosis of wheel alignment parameters, make a correct diagnosis of various violations of geometric characteristics and perform repairs. But motorists with experience prefer to perform these operations with their own hands. This way you can get a more accurate result. And even though the methods by which wheel alignment is adjusted are already pretty outdated, they still exist and show fairly accurate results.

Collapse

Under this parameter you need to understand the difference between the distances from some conditional points. This is the angle that is made vertically and in the plane of rotation of the wheel. If this camber angle is in the red, then the top point on the wheel is directed inward, into the wheel arch. If in the black, then vice versa - out. In order to correctly adjust this parameter, strict conditions must be observed. It is important that the tires have optimal pressure. Smooth rims are also a guarantee of the right angles. Adjustment requires that the steering wheel has normal play or free play. Before starting diagnostics, you need to make sure that all the main hinges and components in the suspension system were fully functional and not worn out. Camber is adjusted by increasing or decreasing the number of spacers. They are located between the rack eccentric and the axis of the lower arm. Now you can find on sale special adjusting plates for adjusting the camber. They are suitable for the wheels of domestically produced rear wheel drive vehicles.

Convergence

This is the direction parametermachine and the plane of rotation of the drive wheel. You can often hear from professional mechanics about the amount of toe angle on one axle. There are cars where wheel alignment is adjusted on each of the axles. Correctly set parameter on the drive wheels is one of the most important factors that determine the stability of the machine. Toe-in is determined by the sum of the differences between the edge of the wheel rims in the rear and front positions. Measurements are taken at the center of the disc height between the same points on the rims.

If the data does not correspond to normal, then it is necessary to set the convergence angles. You can proceed to fine-tuning only after checking the reliability of the fastening of the levers and the swivel stand. This connection should be as reliable as possible. Ball joints mounted on steering rods are also diagnosed. For a good result, you should additionally make sure that the bipod and pendulum mechanism are secure. It is important to remember that after any repairs in the running gear of the car, the alignment of the wheels must be adjusted. This is done by changing the length of the side tie rods.

Caster

This is the angle that passes between the vertical and the projection of the axis of rotation for a particular wheel and the longitudinal plane of the car. Due to the inclination in the longitudinal part, the machine is leveled at speed. That is, she herself comes out of the turn, if you release the steering wheel. Whatever the steering angle, the vehicle will automatically return to the straight-ahead position. Naturally, so the machinewill behave if the camber-toe adjustment is correct. The same behavior can be observed with a properly configured caster. On conventional vehicles, this angle is more than 6 degrees. Athletes-racers adjust this parameter a little higher. This will make the car more stable. It will also increase the car's tendency to move in a straight line.

What is alignment done for?

This adjustment makes the car more stable. Manageability improves. Also, correct angles reduce the likelihood of skidding. And one more thing: if all the corners are set correctly, then the tires will not wear out so intensively, and fuel consumption will decrease.

When are adjustments needed?

Adjustment is necessary if the car constantly pulls to one side or the other out of the straight line while driving. Also, the need for adjustment is indicated by tire wear on only one side or uneven wear. If this is a rear-wheel drive car, they additionally check whether adjustment of the rear wheel camber is required. When visually diagnosing the tread on the front axle, it is recommended to carefully check the condition of the chute. Its edges are important. When the edges of the gutter are the same, then this is a good sign and there is no reason to worry. If one of the gutter edges is pointed and the other is normal, then there is a problem.

However, this is only important with a calm driving style. Adjustment is also necessary if there are certain difficulties in performing certain maneuvers.

Settingdo-it-yourself wheel alignment: ways

There are several methods that are suitable for setting camber angles. For example, you can use a laser pointer. There is also a proven method with a telescopic ruler and a plumb line. Such a wheel alignment adjustment will be carried out with your own hands, maybe not very accurately, but everyone has all these tools.

Before you start

There are a few things to check before you get started.

Make sure each axle has identical tires. The discs should be as straight as possible. Additionally, the steering wheel is set to a straight position, and then the number of turns to the right and left is checked. In order for the adjustment to give a result, the entire suspension must be in good condition. And finally, tire pressure. It must match the manufacturer's settings.

Getting Started: Breakdown

If the front wheel alignment is being adjusted, then they are installed in the forward direction. Further, marks are made at the upper and lower points. Then a plumb line is applied to the wing and the distance between the cord and the rim is measured.

The car must be rolled forward so that the wheel moves 90 degrees, and then the same measurements must be taken. For work it is necessary to dismantle the wheel. Also unscrew the bolts that connect the shock absorber to the steering knuckle. Then move the fist to the distance obtained inmeasurement result. That's all - the angle is adjusted. Now you should put everything back together and take measurements again. The camber rate for a front-wheel drive car is -1/+1 mm. In the case of rear-wheel drive - +1/+3 mm.

Toe setting

The conditions are the same as in the case of the previous adjustment. As for the necessary tool, you will need chalk and a telescopic ruler. Now marks should be made not outside, but inside the wheel, almost close to the rims. Then the ruler is applied with both ends to the marks. Further, the pointer is aligned with zero on the scale of the ruler and fixed. After the car is rolled a little forward until the ruler moves back.

Measurements will show how much tie rod adjustment is needed. If the numbers between the wheels have become smaller, then the rods are shortened. If the difference has increased, then they are lengthening. To adjust the length of the rods there is a special clutch.

Adjustment in service stations: prices

Do-it-yourself alignment on the VAZ-2106 is a common procedure. But in the case of modern cars of foreign manufacturers, especially luxury models, it is best to turn to professionals. This is exactly what the manufacturers recommend. The accuracy on the stand will be very high. For example, in Moscow, many service stations do wheel alignment. The price for passenger cars ranges from 1500 to 2000 rubles. If this is an SUV and business class, then the cost will be from 2000 to 2500 rubles.

For trucks, this procedure will be carried out at a cost of 2200 to 2500 rubles. Thus, if there is at least a little experience, it is better to adjust the wheel alignment yourself. The price for the service may be small, but if frequent adjustments are necessary, this can result in quite a round sum.

Conclusion

So, we figured out how to independently perform the procedure for adjusting the alignment of the car's wheels. Adjustment can be made with a minimum set of tools. This knowledge will be useful for any motorist.
