Diagnostics of the condition of ball joints

Diagnostics of ball joints is required if the following symptoms of malfunction appear:

• when driving, a knocking and grinding noise is clearly audible from the wheel side, which intensifies when driving over uneven road surfaces;
• the increase in speed is accompanied by the wheel rim swinging in different directions;
• turning the steering wheel is accompanied by creaking and grinding sounds;
• uneven tire wear;
• noticeable heaviness when turning the steering wheel;
• the handling of the VAZ 2107 has deteriorated;
• the car has become unstable, which is especially noticeable when overcoming uneven roads.

If the above symptoms are present, the condition of the ball joint must be checked. The easiest way to identify a faulty unit is by ear. To do this, turn off the engine of the VAZ 2107 and, standing with an assistant on both sides of the hood, rock the car. If the ball is worn out or damaged, a distinct sound will be heard from the wheel arch, which will make it easy to identify the fault.

You can more accurately check the condition of the support by the presence of play. To do this, you need to use the instructions below.

1. Jack up the front wheel.
2. Depress the brake pedal all the way and hold it there until the test is completed.
3. Rock the wheel forcefully in a vertical plane. Movements should be made initially up and down, and then left and right. The presence of minimal play indicates that the ball needs to be replaced.

Detection of ball joint play

The latest VAZ 2107 models have special inspection holes. Through them it is easy to check the wear of the ball pin without the need to disassemble the unit.

An indirect sign of ball failure is the rupture of the boot. The performance of the support directly depends on the quality and quantity of lubricant. If there is damage to the cuff, moisture and abrasive debris get underneath it. Therefore, if cracks, tears or other holes are found on the boot, it is recommended to replace the unit with a new one.

The movable connection of the wheel hub with the lever is ensured by a ball joint. This unit is a two-part structure. Inside the case there is a metal ball with a finger on which there is a thread. To eliminate backlash in the assembly, polymer inserts are used, and a special lubricant helps reduce friction during turns.

Types of levers. Automakers use several types of articulated joints.

1. Collapsible control arms feature an inexpensive replacement ball joint. During repairs, the lever along with the support is removed from the car’s suspension, and then a new spare part is installed in place of the worn unit. The only drawback of this design is the need to adjust the wheel toe angle after repairs.
2. Non-separable levers are supplied to the retail chain together with a pressed-in ball joint. On the one hand, no additional adjustments are required, and the process of replacing the lever assembly looks simpler. But the cost of the unit often exceeds all the costs of repair work.

Number of ball joints. After diagnosing the suspension at a service station, a motorist may be unpleasantly surprised by the need to replace several ball joints.

1. The simplest design is the MacPherson strut front suspension, which uses one ball joint on each side. Usually it has a lower location.
2. If the suspension is multi-link, then there is a lower and upper ball joint on each side.
3. There are special rear suspension designs that also use wishbones with ball joints. Most often they are installed on top.

Accessories. Some additional components are supplied with the ball joint.

1. Rubber corrugated boots are used to protect the hinge joint from moisture and dust. The durability of the ball joint often depends on the quality of these elements. If the motorist misses the moment when the rubber cracks, then the days of the hinge are numbered.
2. The locking ring should securely fix the boot on the ball joint. Some manufacturers forget about this element, which leads to the boot jumping off the mounting socket.
3. To install the ball joint on the lever, fasteners are also required. These are bolts with nuts, as well as a special pin nut with a polymer stopper.

Symptoms of wear. The safety of the driver and passengers depends on timely detection of ball joint wear. Before the knot falls apart, the following warning points appear.

1. Most often, a knock occurs in the suspension; it is especially clearly heard when turning, if there are irregularities on the road.
2. In frosty weather, wear of the unit may be indicated by a strong creaking noise while driving.

We have selected 12 of the best manufacturers of ball joints for review. Their products are supplied to all regions of Russia. When allocating seats, the opinion of the expert community and reviews of domestic car owners were taken into account.

Ball joints are one of the most important components of a car, because a sudden failure of the joint can create an emergency situation on the road. This is exactly the detail on which it is completely impractical to save. Our review presents manufacturers who produce balls with the best performance characteristics.

To repair foreign cars and replace faulty components, the best solution is to use ball joints made abroad. In addition, some companies will delight owners of domestic cars with their assortment. This category presents manufacturers whose ball joints have the highest characteristics and are in demand on the market.

5 Sidem

Best Buyer's Choice Country: Belgium (produced in Hungary, Romania) Rating (2019): 4.7

The manufacturer Sidem has its factories exclusively in the European Union, so there is no doubt about the quality of its products. Modern organization of the work process, multi-level control at different stages of production of parts, as well as careful preparation of raw materials determine the excellent characteristics of the product, which, in turn, ensures stable demand in the market for spare parts for automobiles.

Ball joints use a more than durable boot, the upper part of which does not have a retaining ring and is made in the form of an oil seal. This design maintains mobility on the joint while preventing water and dirt from entering the lubricant. The latter is based on polyurea and has excellent water-repellent characteristics.

In addition, the range of products such as ball joints is produced not only for foreign cars. In the majority of reviews left, owners of domestic cars consider the use of Sidem components in repairs to be the right decision - better quality and longer service life easily compensate for the price difference. In addition, almost complete identity of the ball joints with more expensive Moog brand products was noticed.

The widest rangeCountry: GermanyRating (2019): 4.9

For almost a hundred years, this American company successfully conquered the international market for auto parts, but ultimately could not survive and was absorbed by the ZM Friedrichshafen concern from Germany. The Germans introduced traditional order and tightened quality control of products, as a result of which the manufacturer became one of the most popular brands.

The company organized the production of not only the best ball joints - the available range of parts allows them to be used in most automobile models (covers 90% of the market). The quality is so high that in many foreign cars TRW balls are installed on the factory assembly line. Owners of VAZ cars who have chosen bearings of this brand (this part is produced for almost all popular Russian brands) in their reviews express sincere admiration for the quality and reliability of these ball bearings.

Optimal value for moneyCountry: South KoreaRating (2019): 5.0

Despite the wide range of products, it is ball joints from this manufacturer that are most popular on the domestic spare parts market. Having started its activities as one of the divisions of GMB, CTR quickly turned into a separate large company.

Reviews from owners of foreign cars who carried out repair work to replace ball joints with CTR products are satisfied with the results obtained. Data on mileages of more than 60 thousand km speak for themselves - excellent efficiency for spare parts that also have a very affordable price.

2 Delphi

Extended service lifeCountry: USA

More stringent quality control, modern equipment and a carefully selected raw material base provide a high margin of safety and extended service life of Delphi ball joints. If you listen to the opinions of drivers, the company’s products are one of the best in the world. In reviews from owners of various brands of middle-class cars, these American ball joints are in no way worse than the original joints, and in some cases have superior characteristics (especially if used for installation on budget models).

The high quality is also evidenced by the fact that the manufacturer undertakes a warranty during the first year of operation (no more than 50,000 km). But the same reviews confirm a successful trouble-free mileage that is twice as long as the warranty. In this case, we are talking exclusively about original ball joints, which, unlike a fake, physically cannot fail after 10-20 thousand kilometers.

1 Lemforder

Largest safety marginCountry: Germany

This manufacturer specializes in the production of products for repair work, but many car brands use the Lemforder range of parts on their assembly lines. It is this fact that determines the original quality and popularity among consumers.

Required tools and materials for DIY replacement

The table below shows the tools and materials that need to be prepared before replacing the ball joint on a VAZ 2107.

Replacement

You have decided that you will carry out the replacement work yourself. Well, that's right. Extra money saved is never a bad idea.

Today, the service for replacing ball joints costs an average of 2-3 thousand rubles.

Replacement consists of two stages:

• Dismantling old ball joints;
• Installation of new elements.

We will start, of course, with the removal:

• Put the car on the handbrake, disconnect the negative terminal on the battery, place anti-roll bars under the wheels and lift the car using a jack on the problem wheel. You need to think about safety first if you are doing car repairs yourself;
• Loosen the wheel mounting bolts and then remove it;
• Remove the nut that holds the ball pin;
• Using a puller, press the support pin out of its seat. If you don't have a puller, use a pry bar and a hammer. The support is pryed up with a pry bar, several blows are applied with a hammer, as a result of which the problematic part comes out;
• Using any strong lever you can find in the garage, move the suspension arm down a little;
• Now the ball is easily removed from its place. This stage requires the presence of an assistant, since it is quite difficult to complete the entire range of dismantling work with two hands. To be more precise, it is inconvenient.

That's it, the old ball joint has been dismantled, so you can start installation. We can say that the installation takes place in a clear reverse order. But there are some nuances here.

When choosing a support, inspect it carefully for defects. This is especially true for the boot, since the service life of the support as a whole depends on it. The average price of a ball is 300-500 rubles.

Installation

Reassembly is no more difficult than dismantling. But we still advise you to be attentive, careful and consistent.

1. Insert the new ball into its seat on the steering knuckle. To do this, use the appropriate bolts. IMPORTANT! While the car is jacked up, these bolts cannot be tightened completely.
2. Push the suspension arm down, insert the pin of the element being installed into the existing eye, and then secure the pin using the fastening nut. Again, not completely.
3. Lower the car, remove the jack, then rock the car vigorously several times in different directions. Only now all the fastening nuts are tightened until they stop.
4. For the pin nut, a force should be applied in the range from 65 to 95 Nm, and as for the steering knuckle bolts, the force should not exceed 50-65 Nm.

After driving approximately 100 kilometers after replacing the ball joints, be sure to check the tightening of the bolts. When rolling, they may loosen a little, so you will have to tighten them.

As you can see, even replacing a ball joint with your own hands is not difficult. This requires a minimum of knowledge and an additional pair of hands at certain stages of dismantling and reassembly.

Use only high-quality parts purchased from trusted manufacturers and reliable auto parts stores. And never delay repairs if you notice that the ball joint is almost on the verge of complete wear. The consequences may be the most unpredictable.

As often happens, the most popular spare parts are produced by all and sundry, to the detriment of quality and in favor of price. The service life of a VAZ-2110 ball joint rarely exceeds the hundred thousand mark, so there is always a demand for this part. And since there is demand, there is more than enough supply on the market. In order not to throw money away and not experiment with your car and safety, let’s look at the issues of buying a ball for tens in more detail.

Structurally, the support, as one of the main elements of the suspension, bears a huge load.

Not the same as in the classic double-wishbone suspension, but even in the MacPherson suspension it gets a lot of mileage. The main purpose of the unit is to transfer force to the steering knuckle without losing the possibility of angular movements in all planes

. The simplest technological solution for this was a design based on a threaded ball pin, rolled into the body through plastic inserts.

As can be seen from the diagram, it is almost impossible to spoil anything in the simplest design. However, some manufacturers and artisanal cooperative enterprises manage to mess up here too.

Differences between a good ball and a low quality fake

Fortunately, we know how to distinguish a good support for a VAZ-2110 from a cheap fake, not only by brand (more on them later), but also visually:

1. Let's look at the finger
   . The thread on it cannot under any circumstances be cut on a machine. It should only be forged or rolled. Pay attention to the color, it should be ashen with scale. This indicates the correct production technology and heat treatment of the finger.
2. Frame
   . On dozens, the body is ball-welded, but we should see the welding points only on one of the halves. The halves fit neatly, distortions are excluded. The top cover should have a slot in the form of a neat hemisphere, but not an oval or other shape. It is important that the top cover must be made of hardened metal. This can be checked easily - two or three movements with a file, and a damp, low-quality lid will give itself away. The lower part of the body must be strictly cylindrical, and a cadmium-plated grease fitting is screwed into the lower part
3. There is also a hemisphere on the finger, which should also be made of hardened metal.
4. Support work
   . We take the ball in our hands, hold the body and rotate the finger, swaying it from side to side. It is strictly unacceptable for the finger to get jammed - it must turn with a uniform, slight force. If the effort is uneven, it turns with jamming, we immediately look for another option, it’s a fake. If the finger is stuck to the liners and does not give in, we also leave this support, we can do without broken lower arms.
5. Boot and fasteners
   . The boot is made of elastic but durable rubber; it has a metal ring at the bottom for pressing onto the body. Correct supports are sold with fasteners - the nut should be cadmium plated, with a light plastic insert.

Options

As you can see, the quality and durability of a ball joint for any car is built on these important details. And for the VAZ-2110, the support should have the following parameters, if you can check them:

• finger angle - minimum 50°
  ;
• finger swing moment - 0.4-0.8 kGs/m
  ;
• moment of finger scrolling - 0.4-0.8 kGs/m
  ;
• the force of destruction of the top cover (pulling out a finger) is 2900 kgf
