The wheels are shaking from side to side, what is the problem?

One is that the oscillation becomes stronger with the increase of vehicle speed, and the other is that the oscillation occurs at a higher speed, which causes the steering wheel to shake.

The drive axle can be erected first, the front wheel is plugged with safety plug blocks, the engine is started and gradually shifted into the high-speed gear, so that the drive wheel reaches the final test oscillation speed.

If both the body and steering wheel shake at this time, it is caused by the drivetrain. Because the front axle of the front wheel is in a stationary state at this time, if the final test oscillation speed is reached, the car does not shake, then the reason for the oscillation is that the front axle part of the car is faulty; Check whether the positioning angle and toe of the front wheel meet the requirements, and adjust if it is out of alignment; Set up the front axle and test the wheels to check the dynamic balance of the wheels and whether the tires are too deformed.

If necessary, a good wheel can be replaced for a comparative test; Check whether the front axle and frame are deformed, check whether the transmission shaft is bent, and make the dynamic balance of the transmission shaft when possible. Hope it helps!

When the car is driving in a straight line at a certain speed, the front wheels swing left and right, and its driving trajectory is not in a straight line, and the driving direction is difficult to control. When the car is driving, the front wheel pendulum is a common fault, which is divided into two types: low-speed oscillation and high-speed oscillation. The low-speed oscillation is mostly caused by the loose wear of the steering system parts and the excessive adjustment clearance. In addition to the causes of low-speed oscillation, high-speed oscillation is mainly caused by wheel imbalance, front wheel alignment, front wheel deformation and displacement of leaf springs.

When you lift the car and put your hands on the tires and shake them from side to side, you will feel a gap and a sound that indicates that the chassis is time to be maintained. The ability to shake left and right with your hands is caused by the wear of the ball head of the direction machine.

The tires of the car are not balanced, or the axles are unbalanced, or the speed of the car is too fast, the ground is uneven, and the steering wheel is not steady.

If the wheels are shaking from side to side, it may be that there is no good connection between your axle and the wheel, or the wheel may be high and short on one side, so you can get out of the car and check it quickly, between your wheel and this axle. Is it good to combine? And are there any problems with your wheels and tires?

The car is shaking from side to side because there is a problem with the balance of the car's tires, and it is recommended to go to an auto repair shop and ask the master to help adjust the balance.

The hub is deformed and the hub bearing is damaged.

1. The tires are unbalanced.

In the front wheel alignment, one of the inspection items of the tire, if the tire is unbalanced, it will cause the vehicle to drive, the left and right yaw ** jumping up and down, the phenomenon of steering wheel swing vibration, driving the seat is extremely uncomfortable, and it must be equipped with heavy lead blocks on both sides of the steel rim to make it balanced.

2. Dynamic balance.

The asymmetrical weight distribution generated by the force when the tire is rotated, usually at a higher speed. In a tire factory, a balancing machine mounted on tires and wheels tests the wheels, the component is accelerated to speeds of 300 rpm or higher, and the unbalanced force is measured with a tire rotation sensor.

The inner and outer planes of the wheel, these forces are broken down into static and force couple values compared to the unbalanced tolerance (which is the maximum manufacturing limit allowed). If the tire is not selected, it has the potential to wobbly and perform poorly. Dynamic equilibrium is better (more comprehensive) than static equilibrium.

3. The gap between the suspension and the rotation system is large.

Inspection items: steering knuckle kingpin or independent suspension system, bearing clearance, horizontal tie rod ball joint, front wheel alignment and tire pressure, and then focus on checking whether the front wheel is balanced.

4. The steering wheel swimming gap is too large.

When the steering wheel swimming clearance is too large (free rotation angle is more than 300), the vehicle can feel "direction drifting" in driving, at this time should first check whether the steering wheel, fastening bolts and the spline are loose phenomenon, if necessary, disassemble and inspect the internal parts of the steering gear, find out the cause of its failure.

5. The front axle is bent and deformed.

Horizontal torsion bar ball joint pin and ball head seat wear loose and fastening screws loose, steering knuckle kingpin (vertical shaft) and bushing wear loose, exceed the use limit, the matching clearance is too large, can also cause front wheel oscillation, need to be overhauled and adjusted according to the specification.

There are many reasons why the rear wheels oscillate left and right when the car starts

1.inconsistent tire pressure;

2.The brake pump is not working properly;

3.The most important point;

It should be that the dynamic balance of the tires is not good, especially the front wheels (do a four-wheel alignment). You can observe by yourself first, and if you can solve it by yourself, you can solve it by yourself, and you need to go to a 4S shop or auto repair shop for very professional problems.

The cause of body shaking when driving is caused by the chassis system, such as unbalanced wheels, loose suspension parts, and large steering tooth clearance. The details are as follows: Wheel imbalance:

Wheel imbalance is a problem that many cars have, because the tire and steel rim cannot be manufactured to ensure uniform quality, so the wheel must be dynamically balanced after assembly. And with the use of tires, wear and tear is inevitable, so the tires must be dynamically balanced every certain mileage. The requirements of most manufacturers are to do dynamic balancing every 40,000 kilometers, and the standard of dynamic balancing is that the unbalance of the inner and outer sides is less than or equal to 5 grams, so as to ensure that the wheels will not shake when running at high speed.

Loose suspension frame: The chassis suspension is composed of various connecting rods and support arms, which are connected to each other by ball joints and rubber bushings. Normally, these parts are very tightly connected, but as the wear of the ball joint and bushing increases, the parts will loosen between each other, causing the suspension to loosen, and the body will shake when walking.

Excessive steering gear clearance: The steering system of the car uses the form of a rack and pinion to convert the rotational motion of the steering wheel into the swing of the wheels. When the rack and pinion are used for a long time, they will wear out and produce clearance between each other, that is.

Questions. The four-wheel alignment was also done, the balance was also done, and the front and rear swing arms were also changed, but I couldn't find the reason.

What about the steering gears.

(1) The bearing in the hub shaft is too loose or the bearing is damaged. (2) The lock nut of the wheel bearing trips (the thread is damaged), or falls off. (3) Wheel Yi deformation.

4) Partial damage to the tire or poor quality of the egg. (5) Severe imbalance of wheels. If the rear wheel swings is found, the cause should be found out in time and eliminated in time, otherwise it is easy to cause safety accidents.

The rear wheels of the car sway from side to side, which may be caused by damage to the wheel core bearings or loose screws on the rear wheels.

The tires are worn out and deformed, and the wheels are deformed. will cause the car to swing in the back.

What's going on with the rear wheels of the car swaying from side to side, this phenomenon is very dangerous to drive, it should be good to balance the line!

Hurry up and get it done and check it out.

My car has just been gotten out, it's called positioning or something, and it's a matter of a few minutes to go to the repair shop.

The wheels swing left and right in the left rear wheel of the trolley, and the main reasons for the swing of the rear wheel are:

(1) The bearing in the hub shaft is too loose or the bearing is damaged.

2. The lock nut of the hub bearing trips (the thread is damaged), or falls off.

3. The wheel hub is deformed.

4. Partial damage or poor quality of tires.

5. Serious imbalance of wheels, etc.

Automotive suspension systems.

Springs and shock absorbers between the body and tires form the entire support system. The function of the suspension system should be to support the body and improve the ride feeling, and different suspension settings will make the driver have a different driving experience.

The seemingly simple suspension system combines a variety of forces to determine the stability, comfort and safety of the car, and is one of the key components of a modern car.

The suspension system is a general term for all force transmission connection devices between the frame of the car and the axle or wheel, and its role is to transmit the force and torque acting between the wheel and the frame.

1. The positioning angle of the front wheel is inaccurate, and the toe is too large;

2. The front tire pressure is too high or too low or the tire is unbalanced due to repair and other reasons;

3. Front hub.

deformation or unequal number of tire bolts;

Fourth, the transmission system parts are loosely installed;

5. Transmission shaft.

bending, dynamic imbalance; deformation of the front axle;

6. Shock absorber.

failure, inconsistent front leaf spring rate; Frame deformation, rivet loosening, or front axle deformation.

Diagnosis and exclusion:

1. There are two situations of high-speed oscillation, one is that the oscillation becomes stronger with the increase of vehicle speed; The second is oscillation at a certain higher speed, which causes the steering wheel.

When shaking, the drive axle is erected first, the front wheel is plugged with safety plug blocks, the engine is started and the high-speed gear is gradually changed, so that the drive wheel reaches the final oscillation speed. If the body and steering wheel are shaking at this time, it is a oscillation caused by the transmission system, because the front axle of the front wheels is in a stationary state at this time; If the final test oscillation speed is reached and the car does not shake, the cause of the oscillation is the fault of the front axle part of the car.

If mine is helpful to you, remember to light it up, thank you!

Is it a four-wheel alignment? The tires can also be checked to see if there is a problem with the tire pressure!

Summary. Hello! We will be happy to answer for you: the main reasons for the rear tires of the car to shake from side to side are:

1.Tire pressure is inconsistent when driving the body shakes, the speed is fast shaking badly, deviation, there is a feeling of fluttering, first of all, you should check whether the tire pressure of the left and right tires is consistent, if the tire pressure difference on both sides of the front wheel exceeds, you can clearly feel the shake and vehicle deviation.

Problems with dynamic balance The mass distribution of the wheels is uneven, and the tires will produce force couples that change direction when they rotate, resulting in the movement of the wheels.

Wheel deformation After the wheel hub is deformed and out of roundness, it is prone to vibration, deviation and abnormal tire wear and other fault phenomena during driving. When the tires encounter.

Shock absorber failure of the chassis.

I hope mine can help you and have a great day!

If these are not the reasons, it is recommended that you do a wheel alignment.

The vehicle swayed slightly from side to side when driving, which was mainly caused by the vehicle mistracking. There are many reasons for the vehicle to run through, the lack of air pressure of the tire will deviate, the degree of tread pattern wear will deviate, the suspension system design is problematic or the suspension is injured, deformed, displaced, etc., and the above situations will cause deviation. Generally speaking, the problem of mistracking is mostly caused by the tires and suspension.

The solution to the car shaking from side to side.

If you want to solve the problem of the car swaying from side to side, you need to start from several aspects.

First of all, in terms of tires, you can first check the rated tire pressure given by the factory, most of the family cars are set between to, and the pressure values of the front and rear wheels are also different, if the tire pressure is not equal, it will definitely lead to deviation. In order to better use the tires, the position of the tires should be changed every 20,000 kilometers, so that the wear of the tires becomes a little more even. Because the wear degree of the drive wheel is always greater than that of other wheels, different friction forces will also directly cause mistracking.

The second is the suspension aspect. Generally, after a certain number of years of use, the car is prone to suspension aging, resulting in the occurrence of vehicle deviation. After the vehicle is used for a period of time, there will be frame deformation, front axle displacement, negative toe and vertical arm, two front leaf spring shrapnel are different, and horizontal and straight tie rod ball joint pins are loose and so on.

If the mistracking phenomenon is aggravated during braking, it is important to check the brake system, because the unequal braking force of the left and right wheels will also lead to mistracking. First of all, it is necessary to visually check whether there is oil, water or hardening on the brake disc of the front wheel; Under the condition that the brake disc and disc are normal, check whether there is oil leakage in each brake cylinder, whether the fixed support plate of the brake caliper is loose, and whether the friction plate has any unsmooth return.

Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions, will provide you with a satisfactory answer! We hope you find this service helpful. If it helps you, we look forward to your likes and attention.

First of all, your question is what is the cause of the car swaying from side to side. In this case, it is recommended to first check the tire screws to see if there is any looseness, it is recommended to tighten the tire screws, and then check the tire bearings to see if there is any wear and looseness, resulting in wheel shaking. Finally, the main thing is to check the ball head rubber sleeve and screws of the chassis, first tighten the chassis screws, and see if the screws are loosened and tightened poorly.

Then check the rubber sleeve of the chassis to see if there is any aging, cracking, and loosening. Whether the ball joint is worn out excessively and there is a gap, resulting in too large a gap between the various chassis suspension parts, and the vehicle is loose and loose.

It is advisable to focus on the chassis, suspension, wheel screws and bearings.
