Typical malfunctions Niva VAZ 2121. Features of repair and maintenance. Specialist recommendations

I want to immediately draw your attention to the fact that 80-90% of the cars that come to us for service are cars owned by firms, enterprises, government agencies. And of course they kill them as soon as they can. For example, when problems arise with the fuel pump, you open the tank, and there is such dirt that it is generally not clear what was poured there. Okay, I’m the one who’s distracted.

So, on the engine: In general, the engine with a volume of 1,7 liters can be described as reliable, but there is one relatively weak point. These are hydraulic lifters. When twisting and twisting the hydraulic lifters, certain efforts are required: if they are squeezed, they will wedge, if they are not squeezed, then they will unscrew. Therefore, it’s better not to climb into the engine yourself, and in general it’s better not to climb into the engine once again, as they say, don’t interfere with the car’s work. A malfunction of the hydraulic compensators is manifested by a slight knock, and if the malfunction of the hydraulic bearings is not fixed in time, then the valve camshaft starts to eat. Spontaneous clamping of the hydraulic bearings leads to breakage of the oil supply ramp. By 100 kilometers, the chain is stretched, it is single-row there so that it makes less noise. Moreover, if the damper cuts, and it is already plastic there, and the chain even cuts through the head and part of the valve cover. When the chain is stretched, you will surely hear it begin to rattle. And I also want to note that there are spare parts for the chain of very dubious quality. It is better to dig these spare parts in normal trusted stores.

Okay, now the transmission. Handouts, in principle, have never fooled your head if you follow the oil. But the cardans need to be constantly lubricated, meaning the crosses. Drove 10 km and lubricate, because they fail very quickly. It is very difficult to replace the cross, and often the cardan is deformed during the replacement, therefore, in order not to get to replace the cardan, it is better to lubricate the crosses every 000 thousand. A sore spot, that of bridges, that handouts - this is a leak of oil seals. If the oil seal is leaking and you don’t change or add oil during it, this leads to the failure of the entire transfer case. In the latest Niva models, starting from the spring of 10, German oil seals are installed, then there are no problems with them, they serve perfectly, there are no complaints about them. From 2011 to 2005, there was a defect in cardan shafts, and the defect itself was vibration, but basically all these issues were eliminated under warranty.

By suspension. I don’t know why the design of the hubs has not yet been changed, because water constantly gets into the bearings and the lubricant loses its properties. Lubrication, as it should be for maintenance, needs to be changed every 30 km, and for those who bomb off-road, it’s better even more often, preferably after 000 thousand. Moreover, the most interesting thing is that the failed bearings do not betray themselves in any way and do not emit a hum, as on other machines. And in the end, they begin to eat up the hub, and then you have to change not only the bearings, but also the hub, and this is not the cheapest thing. In addition, the front wheel bearings are tapered-adjustable, that is, you need to know how to adjust them, and if you overtighten, it starts to eat the hub. There are no problems with the semi-axes, they have never been crooked. The only thing that happens is that after a good run of thousands so under 15, if it becomes necessary to remove the axle shafts, then such a serious problem arises, because the bearing simply cannot be removed, and you have to use almost gas welding to heat it up and somehow remove the axle shaft . More front! A very common problem occurs in Niva, this is due to drive covers. They are torn all the time, as the design of the case is very interesting. Even when installed, they seem to be slightly turned, and when rotated, they grind themselves. And this leads to the fact that if the cover is not replaced in time, the lubricant is washed out and the drive fails. And under the influence of corrosion, it very quickly eats up the splines of the shaft, and when replacing it, it often happens that the shaft does not happen in services and you have to change the entire drive assembly. Therefore, the drive covers must be constantly monitored, or changed after a short run. Niva has no problems with the rear suspension, at most, if you bomb off-road, then the rear bars can go up to 150 km. But the ball bearings fly out much faster, they go off-road no more than 100 thousand km, but with careful operation they nurse at least 000 kilometers. And do not forget to follow the steering covers. The steering is quite reliable, and runs without repair for about 50 thousand mileage. The steering trapezoid serves from 100 to 000 thousand kilometers, shock absorbers are at least 100 thousand. There may be problems with the front suspension when driving privately over rough terrain, the upper silent blocks fail. Also, when repairing, it should be borne in mind that the axles of the levers rust directly to the beam and it will be very difficult to dismantle them, you may have to resort to gas welding.

On the brakes on the Niva, there are practically no questions at all. Only after off-roading, the rear brakes must be cleaned. The main brake cylinder never fails at all, and the brake cylinders themselves run about 100 thousand.

By electrical. Approximately in every tenth car, squeaks of the heater fan appear. Most often this manifests itself in the cold. This threatens to replace the fan, it is not repairable. The headlight hydrocorrector also often breaks, the tubes burst, and as a result, even if you lift the corrector up to the end, the headlights still shine below the permissible minimum. Another such thing: the thrust ring of the fuel pump gasket, it falls onto the float and the fuel level in the tank is incorrectly displayed. And to eliminate this problem, it is very often necessary to remove the interior floor, panels, trim in order to dismantle the pump. This repair takes 2 standard hours at the service station.

In principle, according to Lada Niva, probably everything. In general, my opinion is that the current current Niva VAZ 2121, with timely maintenance and normal operation, is up to 100 ki. it is generally a hassle-free car. And the main thing is to constantly monitor the condition of the car and regularly undergo maintenance and change all consumables.

If repair is necessary, it can be done with your own hands, the main thing is the choice of high-quality spare parts. To do this, it is better to always work with trusted suppliers, since now you can order everything from online store of spare partsrather than spending a lot of time searching.
