"Lada-Priora" - front suspension: repair, device, structural features

For the first time, "Priora" went off the assembly line in March 2007 and is still being manufactured. The model was wanted to be removed from production, but at the last moment decided not to do it. "Priora" in its entire history has experienced one restyling and a lot of improvements on the technical side. The only thing that did not reach the hands of the engineers-developers of the car "Lada-Priora" - the front suspension. Consider its design, typical faults and repair methods.

The device of regular front suspension

As a prototype of "Lada-Priora" VAZ-2110 was used. The suspension system as a whole remained without major changes. Engineers simply installed springs of a different type and other shock absorbers.

Front suspension VAZ "Priora" - independent type, telescopic. At the core - shock absorber racks, as well as barrel springs. Suspension "Priora" is also characterized by the presence in it of lower levers, equipped with extensions. There are stabilizers of lateral stability.

Racks - hydraulic, shock-absorbing. The lower part of them is attached to the swivel fist by two bolts. The upper bolt has a feature. With its help, you can adjust the alignment. On the rack, a spring is mounted, as well as a special polyurethane compression stroke buffer. There is also an upper support pillar with the bearing. This part is attached to the body by means of nuts. Thanks to the elastic material, this support significantly reduces vibrations and allows the rack to swing at the moment of operation.

A bearing is mounted in this support. It allows the shock absorber to rotate simultaneously with the steered wheels. The swivel fist and front suspension lever ("Priora-Hatchback" is also equipped) are connected together via a ball joint. The braking as well as the traction force is transmitted by longitudinal stretch marks, which are secured to the lever and the front support of the crossbeams through the rubberblock.

The washers are located at the place where the supports, stretch marks and levers are connected. They are designed to adjust the angle of inclination of the rotation axes. The rotary knuckle has inside the closed bearing. The hub is installed inside the element. Further - the bearing is tightened securely with a nut and has no adjustments.

Stabilizer

In the system of independent front suspension there is a stabilizer of lateral stability. As the bar is used. Her "knees" through the posts with hinges are attached to the lower levers. The torsion part is fixed on the body through special brackets and cushions.

Typical malfunctions

Engineers of the VAZ in 2007 were required to release this car, so, as already noted, the suspension from the VAZ-2110 was used almost one in one. Naturally, the children's illnesses were not corrected, and many VAZ-2170 owners now regularly face them. Let's consider the most typical malfunctions.

Noise or knock

A knock in the front suspension ("Priora" -universal suffers this too), as well as a characteristic noise is one of the signs of a malfunction. This has repeatedly faced all the owners of domestic cars of this family. Specialists in the chassis service say that in this case, rack failure is possible. Also during operation, the bolts on which the stabilizer bar is attached to the car body are relaxed.

Another noise can be associated with the wear of the bar or pillows. In the case of racks to get rid of a nasty knock, you only need to replace worn shock absorbers. If the fastener is loosened, it should be tightened. In case of failure of the pillows, they should be replaced. It is not expensive. Now there are any spare parts for Prioru.

Also, a knock can cause a loosened mount, on which the upper support is mounted to the body. Specialists recommend tightening the support nuts. Another reason for the noise is the worn rubber element in the pole support. You need to buy a new part and install it. Then the characteristic noise will be gone.

In the case of wear of silent blocks on levers, stretches or racks, the suspension will also knock. These parts must be replaced. Other faults include worn ball bearings, spring breakages or deformation, compression buffer wear, unbalanced wheels.

Fluid flow from shock absorbers

This problem is often faced by owners of cars "Priora". The front suspension leaks. This happens due to a worn or damaged shaft seal. Also on the element in the process of exploitation can be formed scuffing, the chromed layer is damaged. The leak is formed due to damage or shrinkage of the O-rings on the body. The solution to these problems is the replacement of the assembly.

The post badly resists at the moment of recoil

This fault is typical when the recoil valve or bypass valve loses its leakage if there is not enough fluid in the shock absorber. This is due to scuffing on the cylinder, the wear of the fluoroplastic layer. Often there is a draft of the spring in the recoil valve. Is it possible to repair? "Lada-Priora" in this case is staffed with a new rack. Similar malfunctions will occur when the suspension does not resist the compression stage. Symptoms - bumps and noises in the cabin.

Breakdown

If the suspension has often broken through, then there are two options. This is a worn out spring or a failed rack. It must be repaired.

"Lada-Priora" and large gaps in the ball mechanism

The reason for this phenomenon is the deterioration of the working surfaces of the ball bearing. This can be caused by contamination or damage to the anther. Replace the worn parts.

The machine pulls aside

This also sometimes happens with the car "Priora". The front suspension is not to blame here. For example, the withdrawal of a car from a straight trajectory is possible in the event of a different pressure in the tires or a disturbed wheel alignment angle. A big difference in rubber wear or unbalanced discs is still possible. Also, the car departs from the straight path if rubber parts are destroyed in one of the pillar supports. Unequal elasticity characteristics in springs are possible.

High tire wear

This happens not only because of suspension problems.

Tires will wear out badly with sudden braking with complete blocking of the wheels. The same effect will be observed when the wheel assembly is incorrectly disassembled and in case of an overload.

Selecting racks

The front suspension ("Lada-Priora" wagon including) is no less important than the engine or transmission. Suspension quenches the vibrations that are transmitted to the body from the road through the wheels. The undercarriage should provide stability to the car when driving at high speeds.

If the suspension is too soft, the car will go perfectly straight, but when entering the turn, significant rolls are observed. In the case when it is very hard, there will be no rolls during bends, but there is no smooth running.

But you can find the best option. Now third-party manufacturers offer racks and other spare parts for Prioru. Often these parts are much superior in quality and performance to factory ones.

Undercarriage SS20

These parts for domestic and foreign cars are produced under the brand "System of Technologies". These racks have become so popular due to their high quality. For "Priora" the manufacturer offers 4 variants of products, which differ in their rigidity. Which stands are better? They need to be selected according to the style of driving. The softest are the racks of the "Standard" series. Also available are the rear shock absorbers from the same series.

To increase the carrying capacity, an enhanced version is proposed. Next - the rack "Comfort". According to many car owners, this is the best option. They are tougher than the "Standard", but the suspension works equally well on bad and good roads.

The "Highway" set is suitable for those who like the rigidity of the suspension and high speed. With these racks you can also go on bad roads, but it will be uncomfortable. "Sport" is the hardest version from this manufacturer for "Priora" cars. The front suspension of such a plan for the city is of little use, but for sports competitions - just right.

Kayaba

For "Priora" this Japanese brand also offers reliable racks. Often the owners of these cars purchase these products designed for the VAZ-2110. But the dealers have spare parts for the "Priora" series "Kayaba" Exel-G. However, there may be some problems with the installation.

"Asomi"

This is a domestic brand. The company offers for "Priora" details for the front and rear suspension. As for the racks, it's "Comfort PRO" with gas oil filling or oil "Comfort-Classic".

Which stands are better?

It is difficult to answer this question. Although manufacturers also have quality certificates, very often spare parts for running can not provide the declared comfort of movement and the set life. Reviews also do not allow you to understand what is best. Everything depends on the preferences of the car owner. Today, the air suspension is installed on Prioru .

This system can be done by oneself or by contacting the service station. This solution shows itself very well in terms of comfort and reliability.
