When replacing springs on domestic sevens and other models of the "classic" series, it is important to follow the basic requirements. It is advisable to examine in detail all the elements of the suspension, assess their condition. If compared with front-wheel drive cars, then on the “classic” work with the suspension is much easier due to the fact that the springs and shock absorbers work together, but they have different mounts. You can, for example, remove and replace the shock absorber without any problems. This does not require the dismantling of the spring.

Design Features

Some motorists, when replacing VAZ springs, try to choose long or short specimens. The degree of development is different for everyone, so some individuals, without particularly going into details, simply cut the springs, shortening them by a few turns. Of course, this is wrong - the work of the entire suspension is immediately disrupted. This affects the functioning of the shock absorber, even the comfort of control.

Significantly reduced life of suspension elements. But the installation of elongated springs will not give the machine advantages. It is reasonable to do this only in cases where the car is operated in extreme conditions, its suspension is constantly loaded. During operation, even steel springs sag, which affects the ease of operation. Therefore, sometimes it is necessary to diagnose the suspension and replace worn parts.

Signs of wear

Before you replace the spring, strut, other suspension components, you need to determine if there are any breakdowns in them. Listen carefully to how the shock absorbers and springs work when driving on rough roads. The following signs indicate a need for repair:

1. There are mechanical damages on the spring, defects. Damage is determined by visual inspection. It is advisable to do this on a viewing hole or overpass.
2. Significant reduction in the length of the spring. It can be determined by the reduced clearance of the car. Most often, the drawdown of the springs occurs if the machine carries heavy loads or drives a trailer. The situation is the same with the cars used in taxis.

It is in these two cases that the suspension elements need to be replaced. Springs don't break on their own. This happens solely as a result of an accident, collisions with curbs, the presence of an internal marriage.

What to do?

In the event that you find a breakdown of the springs on the seven, you should not postpone repairs. If you do not do it on time, then the destruction of other suspension components will begin along the chain, which will only make repairs more expensive. It is recommended that all work be done in pairs - if one spring on the front axle is out of order, and the second is even more or less “alive”, both need to be changed. Only in this case you will achieve maximum efficiency of the suspension.

In the event that there is no damage to the springs, but there is a drawdown, spacers can be installed. But it is not recommended to get involved in such modifications, as the characteristics of the car are deteriorating. The probability of going into a skid increases, the braking distance also becomes longer. As for comfort, it also suffers. And in domestic cars such as VAZ-2107, and so Spartan conditions. And if the shock mitigation on the body suffers, the driver and passengers will lose all their teeth.

Preparing for replacement

Before starting work on replacing springs on the VAZ-2107, you will need to perform several preparatory steps. Be sure to stock up on all the tools, in particular the spring compressor.

All work can be performed both on a viewing hole or overpass, and on a flat surface. You will need to perform the following manipulations:

1. Put the car on the viewing hole. It is desirable that there is nothing under the shock absorber - it must be removed.
2. Loosen the wheel bolts.
3. Jack up the car and remove the wheel completely.
4. To remove the shock absorber, unscrew the nuts on the upper and lower mounts. Do not lose the rubber gaskets and metal washers. If they are in good condition, they can be reused.
5. Loosen the nuts securing the lower arm to the axle, but do not remove them.
6. Load the suspension by placing a second jack under the lower control arm. Only in this case willremove stabilizer.

Almost all the manipulations are done, it remains only to completely remove the spring from the car.

Spring removal

On both sides of the car, the springs are removed in the same way. When replacing the VAZ front springs, you need to have a minimum set of tools on hand. Be sure to have a screed - you can not do without it. Next steps:

1. Set the ties opposite each other and compress the spring as evenly as possible.
2. Unscrew the nuts that secure the stabilizer cushion with the key to "10".
3. Completely remove the cushion and stabilizer bracket.
4. Loosen lower ball joint to arm.
5. Lower the second jack under the arm. After the lever is lowered, the spring can be removed.

It makes no sense to press the ball joint out of the steering knuckle - this is a very difficult task and requires a puller. It will be much easier to unscrew the three bolts that secure the clip to the lever. The spring must be compressed as much as possible. Be sure to remove the spacer from the top cup. If it is damaged or deformed, it should be replaced.

Installing a new spring

When replacing springs with your own hands, no difficulties should arise. The only thing to consider is the presence of rust and dirt. Clean all threaded connections in advance and treat them with a penetrating lubricant. The installation procedure is carried out inreverse order:

1. Ties are put on new springs.
2. Twist the zip ties to shorten the length of the spring.
3. Fix the rubber spacer on the top with electrical tape.
4. After installing the new spring, carefully lift the lower arm with a jack.
5. Install the ball cage and fasten the mounting bolts.

How to change rear springs?

In order for the repair to be as effective as possible, it is necessary to carry out diagnostics of the rear suspension elements.

If there are also breakdowns, then it is necessary to carry out repairs. Replacing the springs on the rear suspension is much easier. Here is a brief description of the ongoing work:

1. Jack the car up and remove the wheels.
2. Unscrew the rod that fits the brake regulator.
3. Remove the tee mounting bracket.
4. Unscrew the shock absorber mount from below.
5. Unscrew the nut on the top of the shock absorber.

After all these manipulations, it is necessary to install new springs in reverse order. Be sure to compress the springs with zip ties to facilitate removal. In advance, preferably several hours in advance, treat all threaded connections without exception with penetrating lubricant.
