Have you encountered elements of a car body that are made of plastic? No? For example, plastic fenders on the Lada Vesta Sport are installed from the factory. Manufacturers of such parts assure that a plastic hood, fenders and even doors have a number of advantages over conventional metal ones. And they are installed in standard places using factory fastening elements. Is it really?
Replacing the outer CV joint
In the process of replacing the outer CV joint
The work of replacing an outer or inner CV joint is not very difficult and can be done by any motorist who has at least once repaired a car with his own hands. And in order for the repair to be easier and faster, you need to prepare the following tools:
- Socket heads for “17” and “30”.
- Driver or ratchet.
- Extension for the wrench.
- Jack.
- Wheel chocks.
- Hammer.
- Vise.
Step-by-step disassembly procedure
After you are convinced of the malfunction of one or another CV joint, you can begin to work.
- First of all, we tear off the mounting bolts from the wheel and the hub nut, then we set the wheel chocks under the rear wheels. (To make it easier to tear off the nuts, it is better to use an extension for the wrench - approx.).
- We put the car on a jack and hang the wheel.
- We remove the wheel and, for greater reliability, place it under the car next to the jack.
- Now that this picture appears before you, all that remains is to unscrew the 2 bolts that secure the ball joint to the steering knuckle.
Unscrew the bolts marked with a red marker on both sides.

CV Joint Review
(grenades) for VAZ 2108-2115.
Without causing strong blows, the CV joint will move out of place
If the internal CV joint is supposed to be replaced, then work 1 to 6 should be performed as well, after which, using a pry bar, we remove it from the gearbox and take out the entire assembly.
We take the inner CV joint assembled with the axle shaft to a vice where we clamp it and dismantle it.
- After the “bare” axle shaft appeared before us, the work on removing the CV joint can be considered completed.
Step-by-step assembly procedure
Work on assembling all parts should be carried out in the same order as removal, however, there are some nuances in these works.
- First of all, we put the new boot on the axle shaft; this may cause some difficulties. To make the task easier, the axle shaft can be coated with lubricant.
- Then add lubricant to the CV joint.
New lubricant added to CV joint
All work on changing the CV joint, if the work is carried out correctly, will not take more than 1.5-2 hours. You can check the quality of the work performed immediately after the repair. If you start driving with the wheels turned to the side and there is no crackling, squeaking or noise, it means that the repair was carried out correctly and the car can be safely operated further.
Manufacturing
Currently, there are many enterprises that produce plastic body parts. Therefore, production methods may vary.
For example, the plastic products plant “Avtoritet Plast Plus” produces plastic wings using vacuum molding from ABS plastic 3.5 mm thick. At the points of attachment to the body, they have technological amplifiers connected to the wing using high-strength ultrasonic soldering.
Signs of CV joint failure
The first signs of a faulty grenade are crunching sounds in the area of the front wheel on turned out wheels when starting to move. When the fault is severe, noise appears at less significant loads.
The anther begins to crawl
In order to prevent such damage in advance, you should periodically inspect the anthers from the outside for cracks and integrity in general.
Installation
It was decided to install the injectors not under the headlights, but to the side (we remove the radiator grille and make holes in the bumper). We find a place in the engine compartment to install an additional washer reservoir.
We run a hose from it to the radiator grille, install a tee at the same distance from the injectors so that the liquid flows to them evenly. To avoid delays in the supply of liquid, we install a check valve.
We place the button for washing the headlights in a convenient place in the cabin, for example, on the tunnel. We route the wires from the engine compartment (from the pump in the reservoir) into the passenger compartment through the standard hole in the engine panel (above the pedals).
On a note!
Constant velocity joints, which are sold in the store in sets, include grease, a boot and all the necessary clamps in their sets. Pay special attention to this fact so as not to overpay for additional spare parts and accessories.
I had to change more than one CV joint. Of course, I had to tinker with the first one for a couple of hours, since I didn’t really know all the subtleties, but I changed the subsequent ones almost with my eyes closed.
I bought a grenade for viburnum. The assembly includes the grenade itself, a finger guard and clamps. You can change it in an hour without rushing, it can be done faster. But why rush in such a matter?

Advantages and disadvantages
pros
:
- Price. Plastic parts are much cheaper than metal ones. For example, an unpainted original wing for a Lada Vesta costs 6,000 rubles, and a plastic one costs 3,900 rubles.
- Plastic parts are protected from corrosion and are not afraid of rust.
- Plastic parts are much stronger than metal ones and do not lose their shape after impact. Unlike a metal wing, plastic wings withstand direct and tangential impacts, returning to their original position after contact.
- Plastic parts are more resistant to paint chips. ABS plastic dampens impacts from road gravel, preserving the car’s expensive paint.
- Plastic parts are much lighter than metal ones.
Minuses
:
- The thickness of the plastic element is greater than that of the metal one. Because of this, local modifications may be required during the assembly of body elements.
exhaust pipe of Lada Kalina
Soon there were interruptions in engine operation - the warning light blinked. We connected the DST-12 scanner and made sure that the second and third cylinders were shirking work. Why? The simplest explanation is a defective ignition coil. It is four-pin. One channel is responsible for the first and fourth cylinders, the other for the second and third. Probes on high-voltage wires left no doubt: instead of powerful spark discharges between the electrodes, there was a barely audible buzzing. So, change the coil! After this, the engine started running smoothly.
At 90 thousand the ball joints creaked. Domestic-made units do not last long - on average 20 thousand. This is usually due to rupture of the protective cover and contamination of the friction surfaces. But ours are intact! This means that they have simply exhausted a modest resource. It would be interesting to know whether this resource was assigned by the manufacturer (that is, he is satisfied with the situation on the market) or did everything just turn out “as always”?

The first method of modernization
You can improve the expansion tank cap on the Lada Kalina using the method presented below. It is necessary to purchase a FEBI cover (02269)
. The price of the issue will be no more than 150 rubles. The standard Kalina cover should be disassembled and the valve mechanism removed from it. A similar procedure is carried out with the purchased part.
The original valve assembly is sawed down and removed along with the bead that helps center the spring. The Faby valve needs to be ground off no more than one millimeter. This manipulation will allow you to put him in a new place without any problems. The new valve is installed on the standard cover along with a rubber gasket. The part is screwed onto the neck of the expansion tank. The result is a frost-free lid, the production of which took no more than half an hour and quite reasonable financial costs.
Lada Kalina
Most of Kalina's problems are typical for AVTOVAZ cars. It would seem that if these weaknesses are studied inside and out, then repairing equipment is easy. However, there are fewer and fewer romantics - people who like to tinker with cars - over the years. On the other hand, if the shortcomings of the Kalina have been known almost since the first Zhiguli, then why have they not been eliminated by the plant? Presumably, according to an unkind factory tradition, the patriotic buyer is given the opportunity to continue to perform heroic deeds. But won't he change the Kalina with some foreign car?
Belt Lada Kalina
At the 84th thousand the pump bearing made noise. Investigating its survivability is more expensive for yourself: this way you can even get to the point of overhaul! While changing the pump, we discovered that the timing belt had worn off almost a third on the side surfaces of the pulley and tension roller. Perhaps the pump itself is to blame, warped on a crumpled gasket. But tension rollers with a single-row bearing are not known for their reliability, so they also replaced the roller and the pin.
Old age is not a joy, especially for plastic. Of course, four years is not a long time for decent plastic, but recently the plastic lining of the trunk lid unexpectedly remained in the hand of the “tester” - it crumbled from disrepair. Fortunately, it all came down to a couple of strong words and 160 rubles paid for a new corporate design detail.
What non-standard sizes can be supplied?
Many Lada Kalina car owners want to make the design of their cars more presentable by installing wheels of non-standard width and diameter. The manufacturer allows the installation of wheels with non-standard sizes on the car:
- 175/65 R14;
- 185/60 R14;
- 185/55 R15.
When choosing new wheels, it is important to keep the rim width in mind. It is advisable to purchase only tires recommended by AvtoVAZ. It is important to remember that tire size affects handling. For example, when increasing the bus:
- the car behaves more stable on the road;
- controllability improves;
- The car turns easier.
Simultaneously with the increase in wheel width, the tread begins to drain water from the contact patch worse. As a result, the car handles much worse and other problems arise. Comfort on uneven roads also deteriorates when using low-profile tires. Since low height leads to constant shock to the suspension.
