Do-it-yourself wheel alignment on the VAZ-2107 is not difficult, but you will have to adhere to a number of requirements and recommendations. Otherwise, the rubber will not last long. Camber is a term that defines the angle of a car’s wheel from a vertical angle. In those cases, if the upper edge of the wheel looks out, this is a positive camber. If she looks in, then negative. When adjusting on computerized stands, angles are indicated with the prefixes “+” and “-”.
Basic adjustments
If the camber is incorrectly adjusted on one side, then when driving, the car will carry sideways. During the rectilinear movement, remove your hands from the steering wheel and see where it will “pull” the car. But before that, make sure that the tires have the same normal pressure. In the event of a problem, do-it-yourself wheel alignment on the VAZ-2107.
Convergence means how the front wheels are located relative to each other when driving on the road. But when adjusting, the angle is measured relative to the normal position. At sevens, the convergence angle is positive, for front-wheel drive models it should be negative. This is necessary so that after starting off and while driving, the front wheels become smooth.
If it is incorrect to set the wheel alignment with your own hands, the VAZ-2107 will “eat” tires very quickly. Therefore, to monitor the angles of the front wheels is extremely important, because the cost of the cheapest tire is about 2000 rubles. And the adjustment procedure takes no more than an hour. After a successful repair, you will get the perfect condition of the car. The car will ride smoothly, will no longer be pulled to the side, which will increase safety and convenience.
When to adjust wheel alignment
Before setting the installation angles, make sure that you have the following set of tools:
- Calipers.
- Spanners and spanners.
- Ticks
- Durable thread.
- Metal hooks or push pins.
- Wooden blocks - 2.2 cm and 6 mm thick.
This is the minimum set required. The penetration of WD-40 grease does not hinder, since the nuts and bolts are close to the road surface and dust and dirt constantly accumulate on them. Rust is possible, therefore it is necessary to thoroughly clean the threaded joints before starting repair work on the car. On the inside of the wheels you also need to remove all accumulations of dirt.
When to adjust
Make sure that you really need to do the alignment with your own hands on the VAZ-2107. Be sure to make adjustments if the following symptoms are present:
- The trajectory of movement changes, despite the fact that you hold the steering wheel smoothly. The car is still gradually moving away. But this must be checked when driving on a flat road, with the same tire pressure.
- If there are visible deviations in the installation of the front wheels. In the presence of such symptoms, the rubber will wear out unevenly, and gas mileage will increase. Very often, the suspension and steering elements fail.
- If there was a participation in an accident in which the suspension components of the car or steering were damaged, do-it-yourself wheel alignment on the VAZ-2107 is definitely done. A photo of the steps of the procedure is provided for clarity and understanding of the processes.
- When repairing suspension or steering components, it is imperative to check the wheel settings.
Mandatory conditions
The most accurate check is possible only in workshops on stands. But in the absence of such attributes, you can use the proven "grandfather" method. It is advisable to install the car on a viewing hole, since it will be necessary to unscrew the nuts and bolts of the suspension, and without it it is problematic to do this.
When carrying out work, carefully inspect the entire suspension, the condition of the silent blocks and ball joints, tie rod ends. If there is play in them, then setting the wheel angles will not bring any result, and all the work will be done in vain, the machine will change its trajectory spontaneously.
Preparatory work
Wheel alignment on the VAZ-2107 with your own hands on the rear wheels is not carried out, since the hubs are installed in one position and cannot be shifted to the side. The procedure is done only on the front axle of the car. Moreover, it does not depend on the rear or front-wheel drive of the car. Before starting work, do the following:
- To make the adjustment as accurate as possible, you need to load the machine. The mass of the load should be 320 kg, and it must be distributed evenly on all four wheels. You can seat four people with approximately the same body weight in a car and put a bag of cement in the trunk.
- A prerequisite is a full tank of gasoline. The capacity of the fuel tank in the VAZ-2107 is 39 liters. Make sure that the gas level is close to the maximum mark.
- The tire pressure must be kept at a normal level - if necessary, align it. Depending on the type of rubber, the pressure can fluctuate in the range of 1.8-2.5 bar.
That's all, now you can do the wheel alignment on the VAZ-2107 with your own hands, preparation for the procedure is over.
Front wheel camber angle control
It should be noted that the camber angles are quite problematic to set independently, as there are many difficulties. But to check how much the angle deviates from the normal position, it is possible without much difficulty. To do this, proceed according to the following algorithm:
- Place the vehicle on a level surface and fix its position by substituting the stops under the rear wheels.
- Sit in the car and, turning the steering wheel, make sure that it stands level. The wheels should be parallel to the car body.
- Press the shock absorbers 2-3 times so that the suspension of the machine returns to its normal position. The force should be approximately 40-50 kg. The operation is carried out on all four shock absorbers.
- Take the thread and lock it on the top of the wing of the car so that it passes clearly through the center of the wheel. To achieve an upright position, tie a weight to the lower end. Measure from the top and bottom edges of the wheel to the thread. The difference in values - this is the collapse of the wheels.
For example, the difference is 2 mm. This means that the camber angle is 20 minutes (not degrees). Normally, the angle should be 4 degrees and 30 minutes. Allowed deviation upward for no more than 20 minutes. But this is the case when the machine is loaded with a mass of 320 kg. If there is no load, then the angle should not deviate for more than 20 minutes. from the value of 0 degrees and 5 minutes
Wheel alignment test
As can be seen from the above, you can quickly do the wheel alignment on the VAZ-2107 with your own hands. The order of the work is simple, it is enough to have a little patience, skill will come with time.
The preparation for adjusting the toe-in is the same as in the case of the collapse, the differences are only in the following actions:
- Align the wheels, set the machine on a level surface and place additional load on it. Only after preparatory work can you begin the adjustment.
- To check the toe, you must use a strong thread with hooks tied at the ends.
- Lock the hooks on the front and rear wheels so that the thread passes clearly through the centers of both axles.
- The rear wheels have a 44 mm gauge narrower than the front wheels. Therefore, a block with a thickness of 22 mm must be applied to the front of the rear wheel. The thread is laid on top of this beam.
- Turn the steering wheel so that the thread touches both sides of the front wheel tire.
- Fasten the thread on the opposite side and install 22 and 6 mm thick bars under the rear of the wheel.
Wheel alignment
If installation of wheels is broken, then adjustment will be required. To do this, follow these steps:
- Loosen the tie rod ends of the tie rod couplings.
- Using pliers such as "Cobra", it is necessary to rotate the coupling. Before starting the adjustment, be sure to clean all threaded connections from dirt and dust, and treat with penetrating grease.
- Turn the clutch until the clearance normalizes between the thread and the front tire.
- After completing work, be sure to tighten the threaded connections.
- Similarly, the adjustment is made on the second wheel.
- The total toe must not be more than 2 mm.
