Every motorist understands how important the front suspension of the VAZ 2110 plays. But this unit may have certain problems, characteristic malfunctions, which almost everyone who has more or less little experience in car repair can know and fix. Therefore, today we will talk specifically about the front suspension of the “tens”.

What does the VAZ suspension consist of?

1 — transverse arm mounting bracket, 2 — stabilizer bar cushion, 3 — bar cushion bracket, 4 — stabilizer bar, 5 — transverse arm, 6 — stabilizer strut, 7 — ball joint, 8 — steering knuckle, 9 — telescopic strut, 10 — transverse arm extension, 11 — front mounting bracket for the transverse arm extension, 12 — cross member.

What should you pay attention to?

If you hear a knock in the front suspension while driving, the main reasons may be:

• — Malfunctions in the rack;
• — The bolts have become loose, the stretch marks or cushions with which the cross member is equipped may have worn out;
• — The attachment to the body is loose;
• — The rubber parts have collapsed, and the knocking has a distinct “metallic” sound;
• — A “limp” or even a broken spring knocks;
• — Wear of hinges;
• — Knocking due to wheel imbalance;
• — Settlement or breakage of the suspension spring;

The car pulls to the side when driving straight. The reasons for this malfunction may include:

• — Each spring has its own compression ratio. In this case, the spring that has lost its elasticity must be replaced;
• — Tires have different pressures. We check and correct;
• — The rubber element near one of the strut supports was destroyed. At the same time, a characteristic knocking sound is also heard while driving. The problem is solved by replacing this element;
• — The wheel alignment angles are incorrect. Increased tire wear may be associated with this malfunction.

Tire wear. This may be due to improper driving (rash acceleration, braking, exceeding the permissible load of the vehicle), or other reasons:

• — violations of wheel alignment angles;
• — high wear of the hinges;
• — wheel imbalance;

When driving with increasing speed, metallic noise increases:

• — Check the wheel bearings;
• — When starting to move, a characteristic “crunch” appears;
• — Inspect the CV joints, such a sound can only be made by balls that roll along the grooves, because have too much output.

Knowing the meaning and design of the suspension, you can check its condition every time you inspect the machine on a pit (overpass) and perform maintenance. Pay special attention to the condition of the protective covers on the ball joints. Check to see if any deformations, cracks or dents have appeared on the suspension due to shaking and bumps. You should also check the tightness of all nuts.

Be sure to check the condition of all rubber and rubber-to-metal parts, as well as the ball joint of each wheel. We must remember: a malfunction noticed and corrected in time is much less evil than repairs when everything is already falling apart.

Buyer's choice: cost of support bearing VAZ 2110, its manufacturers and articles

There are many different options on the market. It is advisable to take original parts - article number: RS-67499 or 2110-2902820-RU. The width of the part is 144 mm, length – 148 mm, and height – 62 mm with a weight of 1260 grams.

However, there are plenty of other options with good reviews. Among the well-proven products are parts from the Balakovo plant, as well as products from the Asomi company. The price fluctuates between 750 – 1800 rubles. When choosing a spare part, you should pay attention to the quality of the processing of the edges of the part, as well as the packaging. In addition, the part must have certificates of conformity and quality certificates.

Main nodes

Let's talk about its device. The most important element of the front suspension is its strut (hydraulic telescopic) - indispensable in the matter of shock absorption, that is, ensuring a comfortable ride, without much shaking (as far as possible) over bumps and potholes on our roads. It is thanks to the rack, or rather its steering knuckle with an upper bolt equipped with an eccentric washer and a belt, that makes it possible to change the camber of the wheel.

The following are installed on the rack:

• Special spring;
• Buffer limiting the compression stroke, made of polyurethane;
• Upper support. Its structure is as follows: it is attached to a stand, to which the mudguard is attached with self-locking nuts. Therefore, if you make repairs yourself, do not miss this moment - you cannot use ordinary nuts;
• A bearing that makes it possible to rotate the stand together with the wheels;
• A shock absorber in which a spring and a plunger are installed for better performance.

The ball joint combines the lower parts: the steering knuckle and the lever. The longitudinal braces, lower arms, and supports that the crossbar has are connected to each other by rubber-metal hinges. With the help of special washers, it becomes possible to adjust the longitudinal inclination of the turning axis. An angular contact, non-adjustable bearing secures the wheel hubs.

The cross member is the rod to which the lower arms are connected. It is attached to the body in the middle, helped by rubber cushions.

This, in a nutshell, is the front suspension design. Now let’s look at possible malfunctions, which in some cases can be fixed with your own hands, in others it is better to contact specialists.

How to determine the need for replacement

The silent blocks of the front levers of the VAZ 2110, at the slightest violation in installation or a certain degree of wear, quite clearly make it clear to the car owner about the problem that has arisen. The very first and most obvious sign will be the distinct sound of iron striking in the front of the car, as well as a clear change in the quality of car control.

However, such clear evidence of a malfunction is preceded by less noticeable ones:

• during the control process, the sounds of rubber squeaking are heard, and the louder, the more advanced the situation;
• while driving, there is a clear and uniform tapping sound in the area of ​​the wheels, which indicates poor fixation of the silent block and its gradual destruction due to this;
• if the knocking becomes distinct, it is better to use a jack and examine the silent block more carefully. Perhaps its destruction has begun, as evidenced by cracks appearing on the surface. If this is the case, you need to start replacing as soon as possible.

If time is lost, the connecting elements will collapse, which will lead to wear and gaps between the elements, and the wheel alignment angles will be disrupted. This will affect the functional condition of the car and will only reduce its service life several times.

Possible breakdowns

Knock

If you hear a knock in the front suspension while driving, the main reasons may be:

• Faults in the rack;
• The bolts have become loose, the stretch marks or cushions with which the cross member is equipped may have worn out;
• The attachment to the body has become loose;
• The rubber parts have collapsed, and the knocking has a distinct “metallic” sound;
• A “limp” or even a broken spring knocks;
• Wear of hinges;
• Knocking due to wheel imbalance.

In principle, in any of the listed cases, repairing the VAZ 2110 front suspension, done by yourself, can help, during which you need to replace a worn part or (in the latter case, the reasons why a knock is heard) - balance the wheel.

Vehicle pull to the side

The car pulls to the side when driving straight. The reasons for this malfunction may include:

• Each spring has its own compression ratio. In this case, the spring that has lost its elasticity must be replaced;
• Tires have different pressures. We check and correct;
• The rubber element near one of the strut supports was destroyed. At the same time, a characteristic knocking sound is also heard while driving. The problem is solved by replacing this element;
• The wheel alignment angles are incorrect. Increased tire wear may be associated with this malfunction. If you can’t handle it yourself, it’s better to entrust this task to specialists.

Which support bearings for the VAZ 2110 are better - Supports from SS20 or SEVI

The main question floating around the internet is which props are better for cars: SEVI or SS20? In their reviews, owners often prefer the second option. SEVI also has its advantages. Firstly, it's the price. The cost of such parts is 800-900 rubles. But the quality of workmanship leaves much to be desired - sometimes the clips can crack after only 10 thousand kilometers.

The SS20 gold element costs a lot of money. Its price is close to 1700-1800 rubles. But such elements are capable of covering significantly greater kilometers. The owners of “ten” on the forums mostly recommend this option. Below is information on how to choose the right ball bearing without running into a fake.

Suspension check

Knowing the meaning and design of the suspension, you will be able to check its condition every time you inspect the machine on a pit (overpass) and perform maintenance. Pay special attention to the condition of the protective covers on the ball joints. Check to see if any deformations, cracks or dents have appeared on the suspension due to shaking and bumps.

Be sure to check the condition of all rubber and rubber-to-metal parts, as well as the ball joint of each wheel. Remember: a malfunction noticed and corrected in time is much less evil than repairs when everything is already falling apart.

Required tools for DIY replacement

In order for the replacement of the front shock absorber struts to be successful with your own hands, it is recommended that you first prepare the following list of tools.

Table - Tools required to replace the front strut

↑ Design description

Front suspension

– independent with telescopic hydraulic shock absorbers, helical coil springs, lower wishbones with braces and a stabilizer bar. The basis of the suspension is a telescopic hydraulic shock absorber strut 16. Its lower part is connected to the steering knuckle 19 with two bolts. The upper bolt 18, passing through the hole in the rack bracket, has an eccentric collar and an eccentric washer. By turning this bolt, the camber of the front wheel is adjusted. The telescopic strut is equipped with: a coil spring 7, a polyurethane foam compression stroke buffer 9, as well as an upper strut support 12 assembled with a bearing 11.

Steering

The steering is rack-and-pinion type, with a movable tip hinge attached to the racks. The principle of operation is very similar to the previously mentioned ball joint. Even the design is largely similar, except for the fact that the steering end is attached to the main rod. This is done using two nuts and a long sleeve with internal thread. They are necessary for precise adjustment of wheel toe angles. If this adjustment is not carried out, excessive tire tread wear will occur. In addition, it is possible that the car will pull to the side when driving even in a straight line. For this reason, it is extremely important to promptly adjust the camber and toe angles of the front wheels. Otherwise, you will have to purchase new tires for your car.

Shock absorber

The basis of the entire structure is the shock absorber strut. It houses the front suspension spring. The operation of the entire mechanism is most efficient if these elements are in good condition. In particular, there must be sufficient oil inside the rack. And the spring should not be “sagging”. If the car is used in harsh conditions for a long time, the length of the spring decreases gradually. Despite its apparent rigidity and strength, the coils become closer to each other. Even half a centimeter of drawdown will make itself felt - the entire suspension will begin to work ineffectively. This is one of the elements that makes up the front suspension of the VAZ 2110. You can even repair it yourself. As for the shock absorber itself, try to keep it clean. In particular, it is imperative to change the boot if cuts or cracks suddenly appear on it. Even a small amount of dust will make itself felt very soon. The seal will certainly collapse and the oil will begin to come out.

Disadvantages of MacPherson strut front suspension

It’s worth starting with the fact that this type of suspension is designed for normal, quiet driving on flat roads. In other words, the VAZ 2110 suspension (front) is ideal for operating the car in city mode. If you drive a lot off-road, the suspension elements quickly fail. From this point of view, the double-lever type is much more effective. It is for this reason that SUVs (for example, Niva cars) use a double wishbone suspension. Despite the fact that it has a more complex design, it works many times more efficiently. Among the disadvantages of the MacPherson suspension, one can highlight its rigidity. If this type of suspension is used, the car must have very good sound insulation. And most importantly, all plastic elements must stay firmly in place. It is even advisable to use softening materials to minimize the number of squeaks and other sounds. Moreover, the cause of extraneous sounds may also be a worn front suspension spring. If it is not long enough, then the operation of the entire structure is ineffective.
