Steering control VAZ-2107: description, device and repair

The steering of the VAZ-2107 is very similaron that which was established on old copecks. The only difference is that the size of the steering gearbox is slightly larger. In general, the design is similar.

Steering is one of the important parts in theany car, the failure of one component leads to a complete inability to travel. All maintenance work can be performed independently. The only thing that is better to entrust to specialists is the adjustment of camber and convergence of the front wheels.

Location of the steering trapezoid

All tips and steering rods are located underengine compartment, almost near the ground. If you turn the steering wheel all the way to the end, you can see the tips of the steering rods, which are mounted on the pivoting fists with the help of moving hinges. The design of the trapezoid consists of:

1. One middle tie rod.
2. Two steering links on each side.
3. 6 tips, which are movable hinges.

Elements of the system are fixed by means of nuts with slots, into which pins are mounted, which counteract the rotation.

Breakage of the steering trapezoid

It is necessary to repair the steering of the VAZ-2107, if there are following signs of breakdowns:

1. Significant increase in backlash of the steering wheel.
2. The appearance of a knock on the steering side of it.
3. Uneven or too rapid wear of tires.

Tires can quickly wear out due to the fact that the extreme steering rods are misconfigured or deformed.

When driving it will be felt that the carleads to the side. Be sure to carry out a complete diagnosis of the car, as similar signs also appear during breakdowns of other components of the front suspension. Timely adjustment of the steering VAZ-2107 will avoid more serious problems.

Diagnosis of the steering trapezoid

To diagnose the condition of the tips and steering rods, you need to install the car on a pit or lift and perform the following actions:

1. Inspect the steering tips, paying special attention to the condition of the anthers. On them there should be no cracks and ruptures.
2. On the hinges the maximum play should not bemore than one and a half millimeters. Using the mounting blade, pull the swivel joint to the sides. If strange sounds are heard, replace the tips.
3. The most vulnerable place of steering istips, thrusts are replaced very rarely. They fail when subjected to severe impacts on the suspension or during an accident. In general, if the steering rod is to be replaced, it is best to put a new one. You can not try to straighten the old ones and set them back.
4. The pendulum mechanism is mounted on the right-hand sidecar and is designed to provide synchronous rotation of the front wheels. With this simple device provides maximum stability during the passage of turns.

This is a brief description of the steering of the VAZ-2107 and its characteristic faults. If there is any indication of a breakdown, be sure to perform the diagnosis and repair the breakdown.

The pendulum mechanism

The pendulum of the steering inthe bottom of the bonnet to the right. It is best to inspect this mechanism on a pit or trestle. With the help of the steering wheel joint VAZ-2107, the wheels are rotated synchronously during the rotation of the gearbox. Usually, when a pendulum breaks down, there is a knocking during driving on bumps, the backlash of the steering wheel increases.

It is felt that for the rotation of the steeringwheels need to apply a lot of load. All these signs can also appear if the bolts are sufficiently loosened, or when the adjusting nuts on the gearbox are tightened tightly. Therefore, before repairing the pendulum mechanism, you need to make sure that it is malfunctioning.

Steering column

This is the shaft by which the rotation from the rudder to the gearbox is transmitted. It is fixed with the help of a bracket on the body of the car.

The column is a shaft consisting of crosses. The design is very similar to the cardan. In the event of an accident, the steering mechanism is fully folded, which ensures the safety of the driver.

To facilitate control, the upper shaft rotates on two needle-type bearings. Repair of steering VAZ-2107 is necessary in the event that the following symptoms are present:

1. A script appears inside the column. The cause is usually the deformation of the panel elements and the stalk switch.
2. The increase in the backlash of the steering wheel appears when the nut is loosened, to which the steering wheel is attached to the shaft. To get rid of breakage, it is necessary to tighten the nut, having disassembled the steering wheel.
3. The presence of backlash on the axle appears in the event that the bracket mounts and splines are heavily worn or loosened.

If the nuts and bolts are loosened, the splines will be erased. In this case, the car can easily lose control. Be sure to remove the backlash of the steering column as soon as you find a malfunction.

Rotary fists

The most reliable element in the device of the steeringcontrol VAZ-2107 - this is a rotary fist. It is durable and very durable, but when repairing the suspension it is sometimes necessary to remove it. With the help of swivel fists, the wheel hubs are held. This element is fixed on the lower and upper arms by means of movable ball supports.

During the turn of the helm the gearbox with the help oflevers turns the fist in the right direction. In this case, the car is rotated in the desired direction. Elements made of cast iron are made, so they can withstand high loads without difficulty. One of the most common failures is deformation from strong impacts on the suspension, from driving on uneven roads and after an accident. The following signs may also appear:

1. The increase in backlash due to the breakage of the bearing of the hub and the strong wear of the axle of the fist.
2. Uneven or rapid wear of tires.
3. When driving on a flat road the car gradually goes to the side.

Uneven wear of rubber can be causedincorrect installation of the camber and the convergence of the wheels. Therefore, before blaming all the troubles of a rotary fist, you need to thoroughly diagnose the entire front suspension. It is possible that there is an excessive wear of the rubber blocks or the tips of the steering rods.

Increase of backlash of a steering wheel

In order to check the backlash of the rudder, you must perform the following actions:

1. Put the car on a level platform.
2. Pump the wheels to equalize the pressure.
3. Install the steering wheel so that the front wheels are parallel to the center of the car.
4. Set the ruler so that it rests against the dashboard, lightly touches the light switch and steering wheel.
5. Slowly try to rotate the steering wheel and at the same time watch how the front wheels are located.
6. When the wheels are shifted, the rotation of the steering wheel must be stopped.
7. Make a mark on the handlebar opposite the ruler.
8. Start rotating the steering wheel in the opposite direction until the wheels start turning.
9. Set the second label.

After all the actions taken, you need tomeasure the distance between these two marks. At a normal backlash, which is 5 degrees, the distance will be 17 mm. In the same case, if this value is less, it will be necessary to replace the steering gearbox or clamp the screw nut of the worm gear.
