Replacing Priora front struts: tools, instructions

Front suspension strut - disassembly and assembly

You will need spring ties to get the job done.

1. Remove the rack from the car.

2. Clamp the stand in a vice.

Be careful! A compressed spring has great force and when the tie breaks, it straightens out and can cause injury.

3. Install the couplers and tighten the spring evenly, without distortions, until the load is removed from the upper spring cup.

4. While holding the shock absorber rod from turning with a 6 mm hex wrench, use a 22 mm wrench to unscrew its nut. 5. Remove the limit washer from the upper support of the rebound stroke from the strut rod. 6. Remove the upper compression stroke limiter and the upper support from the rack. 7. Remove the bearing from the upper support.

8. Remove the upper spring cup and rubber gasket.

9. Remove the spring from the rack.

10. Remove the compression stroke buffer and the protective casing of the shock absorber rod.

11. To replace the spring, loosen the spring ties.

We assemble the front suspension strut in the reverse order.

Before assembling the strut, by fully extending and retracting the rod by hand, make sure that the shock absorber is in good condition. If you feel dips, jerks, or hear strange sounds when moving the rod, replace the shock absorber. Check the integrity and serviceability of all elements installed on the rack. Replace a damaged or cracked shock absorber rod guard, damaged compression stroke bumper, or cracked or weakened suspension spring.

Front suspension springs are divided into classes according to their stiffness. The class of the spring is indicated by paint on the outside of one of its coils. The front suspension must have springs of the same class installed.

Basic faults

The main sign of a failed “support” is a knocking sound at the top of the support when driving on an uneven road. It may be a consequence of deformation or mechanical damage to the bearing gaskets, as well as a violation of the integrity of the bearing itself.

A malfunction of the “support” can be caused by:

• long service life;
• exceeding permissible dynamic loads;
• moisture or dirt entering the structure.

You can determine that the support bearing has become unusable in the following way. Lift the hood, remove the protective cover on the “glass” of the pillar, place your palm on its support, and rock the car up and down. If the bearing is faulty, you will hear a characteristic knocking sound accompanied by corresponding vibration. In this case, the “support” must be replaced.

The maximum bearing life for the Priora is 100 thousand km, however, given our roads, it wears out much faster. Therefore, the optimal mileage from replacement to replacement is 50 thousand km. In addition, the bearing must be replaced if any of the above faults are detected.

Useful instructions on how to replace the front struts of a VAZ Lada Priora

Replacing the front struts of a Lada Priora is a rather labor-intensive and complex process, but it can be done at home. You will see this for yourself by reading this article.

The front struts of the Lada Priora are one of the fundamental mechanisms for ensuring control of the car's wheels. If the front struts come out of alignment, it threatens not only with unpleasant dull knocks and squeaks coming from under the wheel arches, but also with a complete loss of vehicle control and destruction of other elements of the front suspension.

It is impossible and incorrect to diagnose the failure of the front struts of a Lada Priora by creaks and clicks near the wheel arches alone. Sounds can also come from faulty ball joints or other mechanisms. Before you begin repairing the struts, it is necessary to conduct a thorough inspection of the entire front suspension, steering rods, levers, ball joints and other parts. When inspecting the front struts, try to move the shock absorber, make sure that it is firmly fixed and there is no play in the connections. Oil smudges on the shock absorber strut are a very bad sign. Traces of oil in the event of a strut malfunction are usually visible on the boot and piston. If you notice something wrong, re-inspect the telescopic stand with the wheel hanging out. This will make any damage easier to notice.

When you are convinced that the cause of unpleasant knocks and squeaks while driving is the front struts of the Lada Priora, collect the necessary set of materials, tools and new spare parts for repairs.

To replace the front struts of a Lada Priora you will need:

• new front struts - you can choose any set from hard and reliable domestic ones to softer, more comfortable, but no less reliable foreign ones. An excellent option for a combination of price, quality, comfort and reliability is hydraulic collapsible front struts from Asomi (Togliati);
• set of socket wrenches for 13, 17, 19;
• set of spanners for 17,19, 22;
• hex key 6;
• tensioning devices for springs - for removing the spring from the rack;
• puller for steering tips;
• hammer, pliers;
• WD-40 liquid;
• jack.

As you can see, the set of tools is not so small. It is unlikely that a novice motorist will have all these tools, but at some point he will still have to acquire them. If you are faced with such a serious matter as replacing the front struts of a Lada Priora, then why not buy them now. Still, buying tools will cost less than repairing them at a service station. Replacing the racks should be made as comfortable as possible so that you are not constrained by the means at hand. They will definitely come in handy in the future.

Which ones to choose and their price

Having decided to replace the rear struts, you will have to choose among today's abundance of original spare parts and their analogues on sale. You can, of course, not bother and buy stock oil shock absorbers from the SAAZ plant, exactly the same as those installed on the Priora on the assembly line.

Part numbers:

• 217002915002;
• 217002915003;
• 217002915004;

Their prices vary from 1200 to 1400 rubles (for one rack) .

If you want to change the characteristics of the suspension, namely make it softer or stiffer, you can purchase alternative struts. The most popular shock absorbers among Prior owners are SS20.

They are distinguished by high reliability, and in addition, a variety of designs that allow you to change the stiffness of the suspension. There are four modifications of SS20 for Priora on sale: “Comfort”, “Standard”, “Highway” and “Sport”, differing in rigidity in ascending order. The cost of a pair of such racks is about 3,700 rubles.

"Technology System" – SS20

As for foreign analogues, the best shock absorbers are Japanese products. They also differ in rigidity and size, which also allows you to adjust the ride height. You can buy such racks at a price of 2,700 rubles per piece.

"Kayaba"

Important: it is recommended to replace shock absorbers in pairs, i.e. if you change it, then change it on both sides of one axis!

How to disassemble an existing structure

1. At this stage, you will need pre-prepared spring ties. They need to be installed on the second coil of the spring. The second tie is installed in exactly the same way, only on the other side.

1. Reduce the spring by twisting the coupling bolts of the first tie. This must be done until the moment when the second tie begins to move freely on the coils. Repeat all these steps on the second screed.

Shock absorber manufacturing plants

There is a huge selection of companies that are better at producing these parts for Priora. And all of them are highly appreciated by our car owners.

• Koyaba;
• Horses;
• Monroe;
• SS20;
• SAAZ.

If the first three companies are foreign manufacturers, then SAAZ and SS20 are purely domestic enterprises. Moreover, SS20 is named so because most of the engineering employees of this company previously worked in the defense industry, and as you know, those who understand their business best have always worked there. And in honor of the famous missile system, which is distinguished by its amazing reliability, the enterprise was named.

Two and one tube shock absorbers

There is also a division of these unevenness compensators according to one more characteristic. These are the so-called two-pipe and single-pipe devices. From the name it is clear that “pipes” are cylinders filled with a compensating composition. In the single-pipe version, this is the same “syringe” in which the rod with the piston moves. In a two-pipe system, the role of the rod is played by a second, hollow cylinder inserted inside the first, which has a valve system at the end for better movement of the compensating material.

Typically, single-pipe systems use a single material, gas or oil. But double-pipe struts most often have a double filler and are gas-oil.

Brief summary

As you can see, replacing the rear struts on a Priora is not particularly difficult. The main thing is to make the right choice and purchase shock absorbers that will last for many years, as well as diagnose them in a timely manner and prevent critical malfunctions.

The rear struts on the Priora, meaning high-quality factory ones, can last more than 200,000 km under normal operating conditions. Of course, not every car can boast of such mileage before replacing rear shock absorbers. If the racks no longer hold, and the back of your Priora begins to float, or its body is covered in oil (leaked), then they need to be replaced with new ones.

Each owner can replace these parts independently; the main thing is to have the necessary tools at hand. In this case, to perform this repair you will need:

• Open-end wrench 19 mm
• 19 mm head
• Ratchet handle or crank
• Hammer
• Penetrating lubricant
• Special key for holding the strut rod

Tips for newbies on replacement

1. Before you begin replacing a part, be sure to check that all components are present.
2. Follow the step-by-step instructions, remember which parts were removed from where, and in what order.
3. When tightening the bolts and fastening the parts, there should be no differences from the original: no gaps, tight and even.
4. It is better to replace the old ones with hydraulic structures; they can be disassembled, it is easier to replace some parts than to dismantle the entire structure later.
5. Don't neglect to use WD-40 before starting work. This will preserve the thread and save effort.
6. If you have doubts about whether it will work, it is better to ask an experienced car mechanic to observe and be present.

Rear shock absorbers on Priora

The rear wheels of the Lada Priora factory also come with non-separable shock absorbers. Their characteristics are similar to the front ones. As many drivers note, these shock absorbers are very soft and do not hold the road well at high speeds.

Analogs of Priora front shock absorbers

Replacements for shock absorbers on the rear wheels of Priors are slightly less popular than those on the front wheels. Often, many drivers install analogues on the front wheels, and leave original spare parts on the rear wheels. Nevertheless, the most popular analogues of rear shock absorbers are presented below.

SS20144

Fenox A12288C3

Kraft KT 073542

Which shock absorber struts for Priora are better? For moderate driving, and at a low price, it is better to take the original SAAZ. Also, shock absorbers from the Russian company SS20 deserve special attention. They produce high-quality and technologically advanced products at a relatively low price. The range is represented by several lines of shock absorbers (differing in level of rigidity). But the most popular for the VAZ 2170 is the “Comfort” series. They are a little stiffer than the factory ones, which is especially noticeable at speeds up to 50 km/h. But after this mark they perfectly reveal their full potential on uneven roads. When entering the pit, the sound is practically inaudible, and most of the vibrational energy is absorbed.

Also of particular interest are shock absorber struts from the Japanese Kayaba (KYB), the big advantage of which is their versatility. They perform well both on smooth highways and off-road. The company has developed gas-oil shock absorbers labeled Exel-G, especially for Priora. But, due to the novelty of these spare parts, they are now quite rare on sale.
