Why can a CV joint suddenly break in the winter?

Constant velocity joints (CV joints) are the most important parts in a car’s undercarriage. The inner one connects the gearbox and the shaft, the outer one connects the shaft and the hub. But in winter there is a risk that these nodes will fail. And it happens along the way and, as always, unexpectedly. The AvtoVzglyad portal tells what could be the cause of the outage.
The CV joint just pulls out due to poor quality repairs. After all, many now began to save. For example, the car owner has replaced the clearance wheel bearing with a new one, but cheaper. And he was married. As a result, when the load on the new spare part started moving, it just crumbled. This created vibrations, which caused one of the hinges to vomit. The result – calling a tow truck because a car with an inverted wheel can fly into a ditch. Everything depends on the speed.
By the way, the hinge has an ominous name – a grenade. Just like the hub bearing, it can also suddenly “explode”. The fact is that now the so-called ball couplings are most commonly used. They consist of a grooved body, a cage and a cage. The separator holds the steel balls on the cage, which roll between the body and the cage. That is, if the separator is worn out, then problems with the car will happen. Especially if the road is wet or has a thin layer of ice.
The fact is that the hinges with equal angular velocities make it possible to transmit torque at an angle. And if the car is driving on a flat road, there are no deviations and the driver does not feel anything unusual. But if in a slippery bend the helmsman did not hold the car and started a skid, then there are increased loads on the CV joints. As a result, the balls start firing, as it were, at the separator living out its life, it falls apart and the balls jump out. At the end of the story, the vehicle ends up on the side of the road.
Another reason for the failure is damage to the protective anther and saving on lubrication. By the way, it also thickens in the cold and needs to be warmed up. That is, move smoothly. Usually this is not checked. Therefore, the anther is torn, the lubricant is contaminated. All this condemns the replacement of an expensive node, as the crackling sound in motion will tell.
