We independently change jet thrust on the VAZ 2107

The basis of safe driving is the stability of the car on the road. This rule applies to both trucks and cars. And VAZ 2107 is no exception. The handling of this car has always left much to be desired. In order to somehow make life easier for drivers, engineers developed a jet thrust system for the “seven”. But any detail, as you know, can fail. And then the driver will face the question: is it possible to change the broken traction with your own hands? Yes, you can. Let's try to figure out how it's done.

Appointment of jet thrust on the VAZ 2107

The purpose of jet thrust on the VAZ 2107 is simple: do not allow the car to "walk" along the road and sway strongly when entering sharp turns and when hitting various obstacles. This problem has been known since early automobiles. At that time they did not know about any jet thrusts, and the cars were equipped with conventional springs. The result was logical: the car easily rolled over, and it was incredibly difficult to drive it. Over time, the car suspension was improved: they began to install a system of long rods in it, which were supposed to take on part of the loads arising from road irregularities or due to too aggressive driving style. On the VAZ 2107 and other classic Zhiguli models, there are five jet rods: a pair of long ones, a pair of short ones, plus a large transverse rod, which serves as the basis of the entire traction system. All this is installed near the rear axle of the car.

You can see this system only from the inspection hole, where all work is done to replace broken rods.

On the choice of jet thrust

At present, there are not so many large manufacturers producing jet thrust for the VAZ 2107 and other classics. Their products differ both in price and reliability. Consider the most popular products.

Traction "Track"

The products of the Trek company are very popular with the owners of the "sevens". These rods are distinguished by high reliability and high price, which starts from 2100 rubles per set.

Jet thrusts "Track" are distinguished by high reliability and high price

The main difference between the "Track" are the heads for the bushings. Firstly, they are large, and secondly, they are attached to the rods by welding. And silent blocks on the "Tracks" are made of especially dense rubber, which significantly extends their service life.

Traction "Cedar"

On the vast majority of the “sevens”, which had previously left the assembly line, jet thrusts were installed precisely from Kedr, since this company has always been and remains the official supplier of AvtoVAZ.

Traction "Cedar" have a reasonable price and mediocre quality

In terms of quality, Kedr is somewhat inferior to Trek. This is especially true for bushings and silent blocks. All this wears out pretty quickly, and therefore, they will have to be changed more often. But there is also a good side - a democratic price. A set of rods "Cedar" can be purchased for 1700 rubles.

Traction "Belmag"

Despite the simplicity and reliability of Belmag rods, they have one significant drawback: they are not so easy to find on sale. Every year they are less and less common on the shelves of auto parts stores. But if the car owner still manages to find them, then he can be congratulated, because he got a reliable product at a reasonable price. The cost of Belmag rods starts from 1800 rubles per set.

Today it is not so easy to find Belmag traction for sale

Here, in essence, is the entire list of large manufacturers of good traction for the VAZ 2107. Of course, now there are a lot of smaller companies on the market that are quite aggressively promoting their products. But none of these firms gained great popularity among the owners of the classics, and therefore it is inappropriate to mention them here.

So what should the driver choose from all of the above?

The answer is simple: the only criterion for choosing jet rods is the thickness of the car owner's wallet. If a person is not constrained by funds, the best option would be to buy Track rods. Yes, they are expensive, but installing them will allow you to forget about suspension problems for a long time. If there is not enough money, it makes sense to look for Belmag products on the shelves. Well, if this idea is not crowned with success, the third option remains - the Kedr thrusts, which are sold everywhere.

Here it is necessary to say a few words about fakes. Knowing that car owners most often choose the products of the three above companies, unscrupulous manufacturers have now literally flooded the counters with fakes. Moreover, in some cases, fakes are made so skillfully that only a specialist can identify them. In such a situation, an ordinary driver can only focus on the price and remember: good things are expensive. And if there is a set of “Track” rods on the counter for only a thousand rubles, then this is a serious reason to think about it. And don't rush to buy.

On the modernization of jet thrust

Sometimes drivers decide on their own to increase the reliability of the VAZ 2107 suspension and extend its service life. To this end, they are modernizing jet thrust. Usually, the modernization of rods means two operations. Here they are:

• installation of twin jet thrusts;
• installation of reinforced jet thrusts.

Now a little more about each of the above operations.

Twin rods

Most often, drivers install dual traction on the VAZ 2107. The reason is obvious: for this procedure with rods, you have to do almost nothing. It’s just that not one, but two sets of rods are purchased, installed in a regular place near the rear axle of the “seven”. Plus, not ordinary, but elongated mounting bolts are purchased, on which this whole structure rests.

The installation of dual rods on the VAZ 2107 increases the overall reliability of the suspension

The obvious advantage of such a modernization is an increase in the reliability of the suspension: even if one of the rods breaks while driving, the car is unlikely to lose control and the driver will always have a chance to notice the problem in time and stop (a jet thrust breakage is almost always accompanied by a strong knock on the bottom of the car, not to hear this is simply not possible). This design also has a drawback: the suspension becomes stiffer. If earlier she “ate” small bumps in the road without any problems, now the driver will feel even small pebbles and pits while driving.

Reinforced traction

If the car is operated in extreme conditions and drives mainly on dirt roads or on roads with very poor asphalt, the car owner can install reinforced jet traction on it. As a rule, drivers make such traction on their own. But recently, large manufacturers have begun to offer reinforced traction of their own production. For example, on sale you can find Track-Sport rods, which are distinguished by a large size of silent blocks and an adjustable transverse bar. A pair of nuts on the transverse rod allows you to slightly change its length. Which in turn affects the handling of the car and the overall rigidity of its suspension.

Reinforced rods have nuts that allow you to change the length of the rod and adjust the stiffness of the suspension

Of course, the driver will have to pay for increased reliability: the cost of a set of Track-Sport rods starts from 2600 rubles.

Checking the state of jet thrusts on the VAZ 2107

Before we talk about checking jet thrusts, let's ask ourselves the question: why is there a need for such a check at all? The fact is that when driving, jet thrusts are subjected to both transverse and torsional loads. Torsional loads occur when the wheels hit large potholes or hit large rocks and other obstacles. This type of load is especially harmful for rods, or rather, for silent blocks in rods. It is the silent blocks that are the weak point of the jet thrust (there is simply nothing to break in the thrust itself: it is a metal rod with two lugs at the ends). In addition, the rubber parts of silent blocks are periodically exposed to the action of reagents that are sprinkled on roads during icy conditions. As a result, cracks appear on the rubber and its service life is rapidly reduced.

The rubber part of the silent block on the rod has become completely unusable

If you believe the operating instructions, then the new jet thrust on the VAZ 2107 can travel at least 100 thousand km. But taking into account the conditions listed above, the actual service life of the rods rarely exceeds 80 thousand km.

From the same instructions it follows that the check of the state of jet thrusts must be carried out every 20 thousand km. However, masters in car services strongly recommend checking the traction every 10-15 thousand km in order to avoid extremely unpleasant surprises. To check the condition of the silent blocks in the rods, you will need an inspection hole and a mounting blade.

Check sequence

1. The car is placed on a viewing hole (as an option - on a flyover).
2. The mounting blade is inserted behind the eye of the thrust.

3. Now you need to rest with a spatula against the jet thrust bracket and try to move the thrust to the side along with the silent block. If this succeeded, the silent block in the thrust is worn out and needs to be replaced.
4. A similar procedure must be done with all other silent blocks on the rods. If they are displaced to the sides by at least a few millimeters, they must be urgently changed.
   

   During the test, the silent block shifted to the left by a few millimeters. This is a clear sign of wear.
5. In addition, the rods and lugs themselves should be inspected for wear, cracks, and scuffing. If any of the above is found on the rods, you will have to change not only silent blocks, but also damaged rods.

Replacing jet rods on VAZ 2107

Before starting work, we will determine the necessary consumables and tools. Here's what we'll need:

• a set of new jet rods for the VAZ 2107;
• rust remover WD-40;
• mounting blades;
• set of open-end wrenches;
• a hammer.

Sequence of work

First of all, two important points should be mentioned. Firstly, the thrust should be changed only on the inspection hole or on the flyover. Secondly, all five rods from the VAZ 2107 are removed in exactly the same way. That is why the procedure for dismantling only one central rod will be described below. To remove the remaining four rods, you just need to repeat the steps listed below.

1. The car is installed above the viewing hole. Silent blocks, lugs and nuts on the central rod are carefully treated with WD40 (as a rule, the lugs rust very much, so after applying the liquid you have to wait 15-20 minutes for the composition to properly dissolve the rust).
   

   WD40 allows you to quickly dissolve rust on the rod
2. After the rust has been dissolved, the area where the WD40 was applied should be thoroughly wiped with a rag.
3. Then, using a socket head with a ratchet, the nut on the silent block is unscrewed (it is best if it is a socket wrench with a ratchet knob, since there is very little space next to the rod). With a second open-end wrench, 17, it is necessary to hold the head of the bolt so that it does not turn when the nut is unscrewed.
   

   The fixing bolt on the rod is more convenient to unscrew with two keys
4. As soon as the nut is unscrewed, the fixing bolt is carefully knocked out with a hammer.
5. A similar procedure is carried out with the second silent block of the central rod. As soon as both fixing bolts are removed from their eyes, the rod is manually removed from the brackets.
6. All other thrusts from the VAZ 2107 are removed in the same way. But when removing the side rods, one caveat should be taken into account: after removing the mounting bolt, the upper edge of the wheel may fall outward. As a result, the holes on the silent block and on the mounting bracket are displaced relative to each other as shown in the figure below. And this creates serious problems when installing a new thrust: the mounting bolt cannot be inserted into the bracket.
   

   Due to the deflection of the wheel, a new mounting bolt cannot be inserted into the rod.
7. If such a situation arose, then the wheel will have to be lifted with a jack until the holes on the bracket and on the silent block of the new thrust are aligned. Sometimes, without this additional operation, it is simply impossible to install a new lateral thrust.

Replacing bushings on VAZ 2107 rods

Bushings on jet rods VAZ 2107 are disposable products that cannot be repaired. It is not possible to restore a worn bushing in a garage. The average motorist has neither the necessary equipment nor the necessary skills to restore the inner surface of the bushing. Thus, the only option for repairing damaged traction bushings is to replace them with new ones. Here's what we need to replace the bushings on the rods:

• bushing press tool (available at any auto parts store);
• a hammer;
• beard with a diameter of 10 mm.

Sequencing

The rods are removed from the car according to the instructions above. Eyelets and silent blocks should be treated with WD40 and thoroughly cleaned of dirt and rust with a wire brush.

1. Usually, after removing the thrust, the sleeve is removed from it freely. But this only happens if it is heavily worn and not very rusty. If the sleeve is literally welded to the rod due to rust, you will have to knock it out with a hammer, after inserting a beard into it.
   

   Usually the bushing falls out of the rod itself. But sometimes you have to beat it with a hammer
2. If the rubber part of the silent block is severely damaged, then you will have to get rid of it. These scraps of rubber can simply be pulled out by prying with a screwdriver or mounting spatula.
   

   The remains of the silent block can be removed with a sharp screwdriver
3. Now the inner surface of the eye should be carefully cleaned with a sharp knife or sandpaper. There should be no rust or rubber residue left on the eye.
   

   Without a thorough cleaning of the eye, a new silent block with a sleeve cannot be inserted
4. Now a new bushing is installed in the eye (and if the rubber was also removed, then a new silent block is installed). It is pressed into the eye using a special tool.
   

   It is most convenient to install bushings in jet thrust using a special press tool
5. If there was no press tool at hand, you can use the same beard. However, you will have to act very carefully so as not to damage the inner surface of the sleeve.
   

   You need to hit the beard very carefully so as not to damage the bushing from the inside.

So, to replace the jet rods with a VAZ 2107, the car owner will not have to drive the car to the nearest service center. All work can be done by hand. Even a novice motorist who at least once held a hammer and a wrench in his hands will cope with this. All you need to do is follow the above instructions exactly.
