The car can snoop or behave unstable, and in such circumstances, its behavior becomes unpredictable, especially during maneuvers. And if you let go of the steering wheel on a straight line, the vehicle will immediately begin to move aside.
There can be several reasons why your car behaves that way. However, the diagnosis of suspension faults should only be made by specialists at a reputable service.
Why does my car feel like swaying?
There may be different problems that lead to vehicle swaying. They are:
- Shock absorber
It is possible that these symptoms produce a malfunction of shock absorbers, which should dampen shocks and vibrations while driving on rough roads. If they are damaged, the car becomes unstable and begins to swing at speed and lose its trajectory. Shock absorbers can break down due to excessive service life, excessive load on the shock absorber shell due to broken baffle, tires hitting the pit at high speed, untimely replacement of the support bearing.
The number of silentblocks in a vehicle depends on the suspension device of a particular model. Usually these parts are equipped with levers, stabilizer stands, underframe and beam. Even if one single silent block is damaged, it can lead to car swaying. Most often they break down due to the destruction of the rubber component, which can be visually determined.
- Ball sockets and steering rod end
They also affect the stability in motion, and any malfunction will cause the car to behave unstable. Most often, they fail due to a ruptured duster, loss of lubrication and contamination of the hinge.
- Hub bearing
As a rule, this element is damaged due to moisture and dirt entering through the torn dust collector. For some vehicle models, the hub bearing is not sold separately and the hub has to be replaced as a complete unit.
- Wheel alignment camber
It is the setting of wheel alignment angles, which determine the steering of the vehicle and its stability in motion. If not set correctly, the vehicle is also usually driven off a straight line or thrown when the steering wheel is in motion.
What is it called when the rear end of your car sways back and forth from side to side?
When the rear end of a car feels it’s being blown by wind, this is known as fishtailing. It usually includes only the rears. You have this problem when the tires skid on the road surface. Actually, it is very dangerous, because a driver loses control of his vehicle. However, it is not always because of bad driving, sometimes conditions like black ice can lead fishtailing. It is typical of vehicles with rear drive. However, front wheel drive vehicles can also have this issue.
Can bad tires cause swaying?
Swaying can be caused by a usual problem with tires like their wear and tear, impaired balance, uneven pressure in the tires. Do not forget that about the tread depth limit, and thus its pattern should be even across all area of a wheel, without stains and strips. You can turn the tires slowly and check the tread which will help locate the problem.
Why does my car drive side to side?
If your car starts pulling in any direction, there are common reasons for that. Of course, there are many factors that affect it such as the fault of the vehicle or the road surface, but more often it happens because of a malfunction such as:
- Wheel alignment
The most common reason that it starts pulling to the right or left is a problem with alignment (descending and falling apart). The most common reason your car sways side to side may be because the tires are too worn out. This can also indicate that the steering wheel is in the wrong position (when the wheels are straight, the steering wheel is in the wrong center).
- Low tire pressure
Another very common reason why the car is pulled to the side is the uneven pressure in the tires. The fact is that if one of the tires has a low pressure, then your vehicle will pull to the side where there is a lack of pressure in the tire. You should check the pressure in all the wheels. If at least one has lower pressure than the other wheels, then insufficient pressure in one of the them may be the probable cause of your car moving to the side.
- Uneven tire wear
If your vehicle is always pulling in the same direction, and the car starts pulling even more as the speed increases, this may indicate uneven wear on the tread or due to the cone-shaped tire.
