VAZ-2109 replacement of rear posts: rules and replacement process

On the car VAZ-2109 replacement rear racksnecessary in case of excessive wear or damage. If we compare the suspension of the "nine" with the "classic", then it is more perfect, the efficiency is higher, and the design is a bit simpler. Although common features are still there - in the design there are springs and shock absorbers.

Only on "nine" they are collected in a single node, andon the "classics" independently installed. Repair and maintenance of the suspension on the car VAZ-2109 can be done independently, you just need to know the overall design of the car and be able to use the tool.

Rear suspension design

The basis of the whole structure is depreciation.rack, which dampens body vibrations when driving on uneven surfaces. Replacing the rear racks VAZ-2109 without dismantling the other components of the vehicle suspension. Rear suspension strut consists of:

• shock absorber;
• metal plates under the spring;
• springs;
• rubber pads;
• fastener elements - nuts and bolts.

All these elements are connected in a single node andinstalled on two sides of the car. It turns out that the design suppresses the vibrations that the entire rear part of the car produces when driving on a rough road.

What is the shock absorber?

In addition, the shock absorber itself includesin a lot of smaller elements. The base is a system similar to a hand pump with something. Only instead of air oil sways. Some shock absorbers can be repaired - it is enough to completely disassemble them and replace all components that have become unusable. You will also need to pour oil, and exactly as much as indicated in the technical specifications for a particular model.

To independently check the healthshock absorber, just lower the body as low as possible. In this case, its stock should enter as much as possible. After this, the body is abruptly released. With a good shock absorber, the body will oscillate 1-3, then stop. But if the device is defective, the body will fluctuate much longer. The reason for this behavior is most likely that the oil has completely leaked out of the body or the sealing rubber rings have been destroyed.

What tool is needed to replace the racks?

When replacing the rear stand bushings VAZ-2109It is advisable to install the car on a viewing pit or overpass. In this position, repairs are much faster, because there are more amenities. To make repairs yourself, you will need:

1. Jack - preferably hydraulic.
2. Supports under the body.
3. Sliding shoes - mounted under the front wheels.
4. Keys set.
5. Spring Remover.
6. Steel wire.

Wire may be required for fixingsprings in a compressed state. But you can instead use steel thick copper or aluminum. Only these metals are much softer and under the action of the elastic force of the spring can stretch.

Preparatory work

Before starting work on the replacement of gumon the rear racks of the VAZ-2109 or dismantling of the elements must be thoroughly prepared. To do this, before starting the repair, treat all threaded joints in advance with penetrating lubricant of the WD-40 type. At least half an hour should be on the metal grease to completely cleaned the thread from rust and dirt.

Only two attachment points at the rear of the nine- inside the trunk upper and lower beam. To remove the shock absorber, it is necessary to unscrew the nuts and fastening bolts. But before that, it is necessary to compress the spring as much as possible and fix its position with steel wire or some kind of rigid braces. The main thing - do not let the spring unclench in the process of repair.

How to remove the rear rack on the "nine"?

To dismantle the rear rack on the VAZ-2109, you need to perform a few simple steps:

1. To weaken bolts of fastening of a wheel from that party on which repair is carried out.
2. Raise the back of the car on a jack.
3. Remove the wheel completely.
4. Place a support under the body and lower the car on it.
5. Check how well the spring is compressed with a puller.
6. Open the trunk, remove the rubber cap covering the shock absorber rod mounting.
7. Use a long tube wrench for 17 or a special tool to unscrew the nut from the stem.
8. Unscrew lower suspension strut mount.
9. Pull out the entire rack assembly.

That's all, now you can repair or replace the rear racks of the VAZ-2109 with your own hands.

Repair or change?

Before some motorists gets quiteA reasonable question is - can you try to restore the old racks yourself, because the cost of new ones is quite high? The cheapest of unknown production and quality will cost no less than 1,500 rubles per piece. If you decide to repair them yourself, it will be at least three times cheaper. But there are several pitfalls:

1. If the resource of the old racks is already decent, then a strong development may be present on the stem, due to which it is sometimes impossible to achieve perfect sealing.
2. It is unlikely to get inside the shock absorberas much oil as necessary for proper operation. If you go down a couple of grams - the shock absorber will not work. If you pour above the norm - seals will tear.

And the quality of items in repair kits often leaves much to be desired. Therefore, replacing the complete stands is much more effective. The resource they will be much higher than the restored.

Assembling the rear rack "nine"

And now a few words about how to producecorrect replacement of the rear racks VAZ-2109. Many motorists change only the shock absorber and airbags, do not attach much importance to the springs. And they should pay attention. As they wear out, they subside, and the length of all turns becomes less than necessary. As a result, the entire suspension will not work properly.

At assembly it is necessary to follow the following rules:

1. Install a compressed spring on the rack.
2. Secure the rubber pads on the last coil of the spring using insulating tape.
3. Carefully, trying not to move the spring relative to the shock absorber, set the strut in place.
4. Affix the nut on the top of the damper stem.
5. Install the bottom of the rack on the beam. Secure with a bolt.

Tighten all threaded connections after finishing.assembly and remove the puller from the spring. After that, you can put the wheel in place and start repairing the second side in the same way. It is advisable to repair the final tightening of the nuts after the car is installed on the wheels. And after 20-30 kilometers, check the tightness of all connections - sometimes the nuts get out after driving. Try to use nuts with plastic retainers on the threads.
