Tie rods are important parts of the Chevrolet Niva suspension. They limit the movement of the rear axle, preventing it from moving forward or backward.
When driving off-road, the rods are subject to a high load. This may cause their deformation, wear of the silent blocks or breakage of the fastening.
As a result, the position of the rear axle is disrupted, the car begins to pull to the sides and tire wear accelerates. Therefore, you need to monitor the condition of the torque rods and silent blocks of the rear suspension.
What links are included in the rear suspension?
The Chevy Niva bridge is held in place using five parts. To prevent longitudinal and transverse displacement, four longitudinal rods (two each: front and rear) and one transverse rod are used. At the ends of the products there are eyes into which silent blocks are inserted to prevent knocking in the suspension. One end of the rod is attached to the bridge, the other to the car body.
The parts have the same diameter and differ only in length. The longest is the transverse thrust. The length of the elements ensures vertical mobility of the rear axle. Thanks to this, the silent blocks do not twist, even if the suspension moves by the full stroke of the shock absorber.
Types of breakdowns and their causes
The parts are made of high-strength alloy steel, so they are practically not subject to deformation.
The jet rod can only bend as a result of hitting large stones or tree stumps off-road.
More often, car owners have to deal with other problems:
- Cracks in the welds between the rod base and the eyes. If a breakdown is not detected in time, the part may fall apart while moving.
- Corrosion of rods. A rusted base loses strength and is easily deformed or broken.
- Wear and damage to rubber bushings of silent blocks. Over time, rubber dries out and cracks. This process is enhanced by physical activity. As a result, play appears in the connection of the rod with the bridge and the body. This worsens the car's directional stability and can lead to the lugs coming off.
Important: the appearance of a knock in the rear suspension may indicate wear of the torque rod silent blocks. If the malfunction is not corrected in time, the lugs will quickly come off under the influence of increased shock loads.
Which ones are better?
There are parts from several manufacturers on the market, among which the following options can be distinguished:
- Cross and Detal-Resurs are two budget brands that produce suspension parts for the Niva. Price - from 1600 rub. per set.
- Sitek - budget spare parts with rubber or polyurethane silent blocks. They are distinguished by their small wall thickness and low weight. Suitable for those whose route mainly runs on asphalt. Price - 2200 rub.
- Niva Urban - inexpensive high-quality spare parts for Niva Chevrolet. The manufacturer produces rods for the entire VAZ family. Price - 2600 rub.
- UG is another budget rod from a little-known company. Like Sitek, they are not intended for active off-road running. Price 3000 rub.
- SC is a more expensive model, characterized by a rectangular cross-section. Judging by the mass, the manufacturer did not spare the metal. The quality of the seam does not cause any complaints from car owners. Price - 3400 rub.
- Niva Extreme - reliable, durable suspension parts that are preferred by fans of extreme racing. The only drawback is the price, which is almost 5,000 rubles.
Note: the high price of Niva Extreme parts is due to their non-standard design. These are enhanced traction.
Reinforced rods
The appearance of cracks between the rod base and the lugs will shorten the service life of the parts. This problem can even cause an accident - the car suddenly pulls to the side when the traction breaks.
To avoid unpleasant surprises, special reinforced parts are installed in the rear suspension. They are made of alloy or cold-rolled steel and differ from conventional ones in the diamond-shaped section of the base and powerful welding seams that hold the lugs.
Reinforced rods differ from standard ones in the following characteristics:
- Reduced weight of parts.
- Improved paint coating that prevents corrosion of elements.
- High strength welded seams.
- Increased resistance to torsion, compression and tension.
Installation of reinforced rods is recommended for full use of the Chevrolet Niva off-road. They don't offer much benefit for city or highway driving. Under gentle operating conditions, the strength of standard rods is quite sufficient, so there is no point in overpaying for reinforced parts.
Advantages and disadvantages
The car demonstrates good off-road qualities. They clearly appear after lifting to install rubber with an increased outer diameter.
Comfort in the cabin is preserved not only on asphalt. This is facilitated by the independent front suspension along with fairly soft springs.
However, many owners of the Chevrolet Niva note the insufficient strength of the reaction rods holding the rear axle.
Those who plan active off-road trips should take care of reinforcing the parts. Kits of reinforced reaction rods are sold for this purpose.
Also in need of attention are ball joints with silent blocks, which are not durable. To extend the service life of the hinges, it is necessary to monitor the condition of the anthers in order to change them on time.
Replacing jet rods
The work is carried out on an overpass or inspection ditch. To replace jet rods you need to prepare:
- hammer;
- a pair of spanners 19;
- metal brush for cleaning threads;
- mounting blade;
- WD-40 liquid.
Reaction rods need to be changed in the following sequence: transverse, front, rear. You should not lift the rear axle with a jack, otherwise there will be difficulties in aligning the holes of the silent blocks and mounting brackets.
Purpose of jet thrust
The reaction bar for the Chevrolet Niva car is a suspension element, the purpose of which is to limit the movement of the front steering knuckle or rear axle, depending on their location.
Tie rods are part of the suspension design, and their main purpose is to hold the wheel in place in the longitudinal direction. The rods are designed in such a way that allows the lever to move freely to the upper or lower position. The fastening to the lever is provided by a rigid tie at two points, and to the body by bolts that are threaded and secured into silent blocks.
Rear torque rods are used primarily in the design of independent multi-link suspension. They are designed to retain oscillatory influences in the transverse direction of the bridge. The rear reaction rods are attached to the suspension due to the fact that both ends are mounted through silent blocks. One edge is attached to the body, and the other to the axle of the Niva Chevrolet.
Transverse jet thrust has a longer structure than longitudinal ones. This is due to the fact that the possibility of moving the bridge can be quite significant. Thus, in order to achieve significant mobility, these elements are lengthened. Even if a situation arises when the bridge moves over the entire length of the shock absorber, the structural elements of the product (silent blocks) practically remain motionless (do not twist).
What are they made of and why do they need to be changed?
Tie rods are made primarily of cast elastic steel, designed to withstand high loads over a long period of operation. But if they consisted only of a cast steel base, then they would almost never need to be replaced. But an important element of this product are silent blocks or eyes. They are an integral part of the rods, which are attached by welding. Silent blocks are not poured together with the production of rods, so I rightfully recognize them as the weak link of this product. A small crack in a weld can cause the product to disintegrate on the road, so it is necessary to monitor and replace them at the first sign of trouble.

We will tell you how to properly perform tuning modifications in this material.
Do-it-yourself elevator - drawings, diagrams, sizes, types of kits. Lifting varies in the degree of intervention in the standard structure. For some, it is enough to raise the SUV by a few centimeters, and for others by as much as 20.
Extreme tuning – maximizing cross-country ability for traveling on severe off-road conditions.
- Regular jack
- Hijack jack
- Spring puller
- Balloon wrench
- Ratchet socket set
- Set of open-end wrenches
- Mount
- Wooden deck (stump)
It is advisable to perform such work with a partner. First of all, it's safer. Secondly, some lifting work is performed with four hands. Let's take the front suspension as an example.
Raise the front end. You can safely cling to the standard bumper, only the jack is installed under the pipe securing it. By removing the wheel, we get full access to the lever and spring. The front suspension 21214 is made using a double wishbone design, which simplifies the task.
The lever travel is limited by the shock absorber. Unscrew its fastening and move it to the side. Next you need to free the suspension from the anti-roll bar. The mounting bolts may become stuck due to corrosion, so we will use a penetrating liquid (such as WD-40). The stabilizer silent block clamp can be pryed off with a pry bar.
Then disconnect the hub from the lower arm. To do this, you need to jack up the suspension and fix the steering knuckle of the wheel. You can tie it with wire. Then unscrew the 3 mounting bolts and release the ball joint.
We fix the spring with ties and lower the jack. We remove the old elastic element. In some cases, it is enough to simply lower the lever with your foot, and the spring will come out without the use of ties.
Remove the upper support rings from the old springs. With their help, the elastic element is centered in the cups.
They come together easily with a hammer and screwdriver. We install the rings on new, longer springs. We put the elastic elements in their regular places and jack up the lower arm until it is completely aligned with the lower cup. At the same time, an assistant centers the shock absorber eye and moves the steering knuckle to the mounting location of the lower ball joint. We tighten the ball “triangle” and attach the shock absorber mounting axis.
By manipulating the jack, we “catch” the mounting holes for the stabilizer bar clamp. With its bolts it should get into the normal place without distortion. After such modernization, the clearance increases by 30-50 mm. This is enough to install wheels of larger diameter, and the bottom will still rise above the ground.
The rear axle of the Niva can be lifted by installing spacer supports of increased height. When using a size of up to 50 mm (according to changes in front end height), no modifications to the rear axle are required. By lifting the rear axle, maintenance can be carried out on the axle and brake system.

The handbrake cable may need to be replaced. It is lengthened by a couple of centimeters. Otherwise, the Niva lift will lead to increased wear of the brake pads in the rear drums. Disconnect the lower shock absorber mounts and lower them until the springs stretch.
We take out the elastic elements and knock off the support rings from them. We clean the upper cup and carry out anticorrosive treatment. We install new supports of increased size and seat the springs using a jack. We fasten the shock absorbers, assemble the axle, and mount the wheels.
Such a lift will not arouse suspicion among traffic police inspectors, and the cross-country ability of your NIVA 2121 will improve. No drawings, much less homemade parts, are required. You buy new springs and about the rates, the rest is a matter of technology. Labor costs for an elevator of one NIVA are two people/one day off.
Making a Niva-2121 elevator with your own hands, the drawings, the dimensions of which are freely available, will not be difficult. Thanks to such a trick, you can make your car more stable on the road and overcome a lot of obstacles with it. Of course, to bring a truly high-quality Niva elevator to life with your own hands, you will have to work hard.
The process will take time and require effort, because even the easiest elevator requires a significant immersion in the technical aspects of the issue. However, the end result will live up to all expectations, allowing the modest Niva to show its exceptional side.
For lovers of hunting, fishing and country travel, as well as those eager to try themselves and their own “Niva” in driving a vehicle in difficult-to-pass places, we have the opportunity to offer an increase in ground clearance, which increases the cross-country ability of your car.
Niva tuning – suspension lifting.
At the moment, there are at least 6 types of suspension lifting for Niva and Sh/Niva, each is interesting in its own right and is negotiated during the preparation of the car for “off-road” at the request of the visitor, taking into account the distinctive features of the operation of his car and the sizes of wheels and tires he uses wants to put it on his car.
We often use a kit from the Russian club 'Korovka' as a base. This lift kit was made at the factory and was tested at competitions in Russia. The ground clearance increases by 5 centimeters, which actually makes it possible to install R15 235/75 or R16 235/70 tires (on the right wheels). In addition, this will provide a rise of another 4 centimeters.
In total, the increase in ground clearance will be 9-10 cm! In this version, “NIVA”, without loss of comfortable qualities, has the ability to be used both on paved highways and off-road, being in no way inferior to foreign-made SUVs.
Consequently, at the lower point of the RZM the clearance is 25 cm, and at the cut of the threshold - 44.5 cm.
Front suspension lift.
The lift is performed by installing targeted washers under the lower spring pad (they create a sufficient angle for the front spring). Under the upper arm (between it and the ball) another spacer washer is placed (i.e., we unload the arm).
The levers of the steering knuckles are swapped and the tips of the control rods already go from top to bottom (since subsequently the work done before, when the rod is fully turned, they will rest against the stabilizer, although at the request of the visitor it is possible to leave it as it was by changing the fastening of the stabilizer).
During lifting work, it is often necessary to change shock absorbers, springs, and resins on request. spacers, internal CV joint boots on tuning suspensions modified for this type of lift and create adjustments. spring bumpers.
Lifting the Niva suspension at the rear.
The lift is carried out by installing new rear spring cups, which are bolted on top of the standard ones, and brackets for moving the mounting points of the rear shock absorbers up 5 centimeters (bolted).
The short upper rods of the rear axle are lengthened or made adjustable (for easy rotation of the shank, so as not to bite the crosspiece), the reaction rods of the rear axle are either reinforced with an angle or installed double; at the request of the visitor, a rear axle stabilizer “Tehnomaster” (Tolyatti) is added, although it will be needed adjust to the elevator machine, digest.
Similarly, it is preferable, on lifted cars, to use a rear CV joint. Those who begin to lift old or worn-out cars need to remember about the internal CV joints (the balls leave their place) and will need to prepare for their replacement. The solution to this difficulty is quite possible by reducing the drive angle by untying the front axle.
The outer CV joints are too little susceptible to this, it will be worse for them if the wheel becomes larger in offset, width and weight, and then they can “crunch”. Although even then the hub bearing has a hard time, especially if it had play before.

Although we have avoided this problem, since we install steering knuckles with 2 ball bearings (from the rear axle shaft), they do not need to be adjusted; they are tightened all the way, although it is much better with a torque wrench. The unit comes out maintenance-free, the hub is unloaded, rolling is easier and the dynamics of the car are much better. Steering knuckles are naturally of domestic production and with a guarantee.
When installing wide wheels after a lift, you will need to keep in mind the ball ones (when the weak ones “fly”), the pendulum will also be able to fly, and the installation of the latest gas shock absorbers results in a stiffening of the upper bracket of the lane. shock absorber (otherwise it tears, especially when the front end is heavier), the mounting of the rear shock absorbers can also be strengthened. It is preferable when lifting, replace the suspension with p/urethane instead of rubber.
Economical Niva suspension lift of 1.5-2 centimeters. In such a situation, we resort to replacing the rubber spacers for the springs with tuning ones (of greater thickness), installing washers, spacers for the upper ball joints and adjusting the spring bumpers (at the visitor’s request). In this implementation, the Niva gets wheels (correct) in size R15 215/75.
Purpose of jet thrusts.
In the Chevrolet Niva, torque rods are a suspension element. Rods are installed to limit the movement of the rear axle or steering knuckle. The wheel is fixed in the longitudinal direction, but at the same time moves freely up and down. Fastening is carried out using bolts on the lever on one side and using silent blocks on the body on the other.
Rear links are used if the car is equipped with a multi-link suspension. They perform the same function - they hold the longitudinal movement of the bridge. They are attached using silent blocks to the bridge and car body.
Depending on the location they have different lengths. Longitudinal rods are usually shorter than transverse rods. This is because the bridge can deviate over a considerable distance.

Why is there a need for replacement?
The thrust rods themselves are made of high-strength material to withstand high loads that occur during movement and long-term operation of the vehicle. But using only one metal in the manufacture of rods is impossible. At the mounting points, special eyes are made into which silent blocks are installed. They are installed in the rods directly at the factory and secured by welding. Therefore, they are the weak point of the system. If errors were made during manufacturing and microcracks appeared, this could eventually lead to destruction of the product. Therefore, it is important to correct the malfunction in a timely manner and periodically diagnose the car.
The design also includes rubber bands that protect against dust. If the seals are damaged, the rubber bands bear increased load. They begin to deform and tear. Over time, this can cause the rod to come off.
But it is impossible to constructively do without oil seals. Therefore, the rod must rotate slightly to compensate for the movement of the suspension.

In every car, the weakest point is the chassis. When driving on asphalt, the car's suspension experiences virtually no stress. But when traveling off-road, traction is most often affected. This is especially true when operating an SUV such as the Chevrolet Niva. Therefore, it is better to take care of strengthening the reaction rods or rods in advance.
Installation of reinforced rods
To increase the life of the suspension, to be more confident in the condition of the car, you have to use higher quality, but also more expensive parts. Reinforced thrust rods of the Niva Chevrolet are made of more durable materials. In addition, the place of welding seams is processed more carefully to prevent the occurrence of cracks. Some reinforced rods are specially made not round, but diamond-shaped. According to experts, such angles of rigidity allow them to withstand stronger loads.
In general, there are several criteria that distinguish enhanced jet thrusts:
- lower weight
- high quality production. The special shape allows protection against twisting and compression, which gives an advantage when driving off-road.
- factory production
- Technological painting. The use of powder coating helps prevent corrosion due to higher adhesion to the metal. This also protects against the occurrence of microcracks.
Signs that the rods require replacement
Typically, a problem with torque rods manifests itself in the form of vibrations when starting off or changing gears. If these symptoms occur, it is necessary to carry out an external inspection of the rods for malfunctions. To do this, the car is placed on a pit or viewing platform and the welding points and the condition of the rubber bands are examined. It is also necessary to check the backlash of the reaction rods. If there are problems, replacement is required.
As a rule, the entire set is changed completely, since the load on them is distributed evenly and if there are problems with one, it may soon be necessary to replace the other rod.
Is it worth doing the repairs yourself?
Any repair requires not only experience, plumbing skills and a standard set of tools. Most operations are performed on an inspection pit or overpass.
To replace ball joints and silent blocks, pullers are required, and checking and adjusting the alignment angles of the front wheels is carried out only on special stands.
Repairing a car yourself is worth it only if you have the necessary equipment and tools. It is often cheaper to go to a service station than to buy pullers or keys for a one-time job.
Suspension repair is a serious process on which your safety on the road depends. If you are not confident in your abilities or do not have the necessary tools, it is better to turn to professionals.
