What are the symptoms of a broken shock absorber bearing, and will there be an abnormal sound when t

After the shock absorber bearing is broken, the car will make abnormal noises when passing over speed bumps or some bumpy roads. And when playing the direction, the car may also have abnormal noises. Replacing the shock absorber bearing is more troublesome, so the labor cost is relatively high.

When replacing the shock absorber bearings, you need to put the shock absorbers.

If you remove it, then you need to disassemble the suspension link to remove the shock absorber, so there are more things that need to be removed. After the replacement, the wheel alignment needs to be redone.

After opening the engine cover, you can see the top of the two shock absorber towers, then there is generally a dust cover on the top of this tower, and after opening the dust cover, you can see the shock absorber plane bearing. If your car has an abnormal sound in the direction of the road, and the abnormal noise on the bumpy road, it is most likely that the plane bearing is broken. It is necessary to pay attention to the fact that the shock absorbing bearing also needs to be lubricated, and the grease should be added to the inside of the shock absorbing bearing frequently, and the dust cover must be covered, otherwise it is easy to enter the dust.

Since the replacement of the shock absorber bearing requires disassembling the suspension parts, after the replacement, be sure to redo the four-wheel alignment. Otherwise, the car may deviate or the tires may wear off. Usually, when crossing some speed bumps or bumpy roads, be sure to reduce your speed to pass.

When hitting the direction, don't kill the steering wheel, if you kill it, you can correct it a little. Don't drive your car on the curb rocks on weekdays.

Car front bearing and frontShock absorbersThe difference between abnormal noise is: different sounds, different durations, and different abnormal noise road conditions

First, the sound is different:

1. Abnormal noise of the front bearing: there will be (buzzing sound) when the vehicle is moving.

2. Abnormal sound of the front shock absorber: there will be (when the sound is sound) when the vehicle is moving.

Second, the duration is different:

1. Abnormal sound of the front bearing: the sound is continuous and becomes louder with the increase of vehicle speed.

2. Abnormal sound of the front shock absorber: the sound is intermittent and has nothing to do with the speed of the vehicle.

Notes: 1) "Vehicle" refers to motor vehicles and non-motor vehicles.

2) "Motor vehicle" refers to a wheeled vehicle that is driven or towed by a power unit and driven on the road for personnel or for transporting goods and carrying out special engineering operations.

3) "Non-motorized vehicle" refers to a vehicle driven by human or animal power on the road.

and motorized wheelchairs and electric bicycles for the disabled that are driven by power units but are designed to meet the relevant national standards in terms of maximum speed, empty mass and dimensions.

and other means of transportation.

When the front bearing of the car is damaged, the front wheel will make an abnormal sound when it rotates, and there will be no abnormal sound when the car is stationary. Moreover, the frequency of squeak and squeak tends to be higher at high speeds. When the front shock absorber of the car fails, the car will also have a slight abnormal sound when it is idle and stationary, and when driving on a good road surface, the abnormal noise will occur from time to time, and when the road is bumpy, the abnormal sound is more intensive. ‍

The bearing is a rotating part, which has to play a role as long as it is running, and the frequency of abnormal noise is directly proportional to the speed of the vehicle. The shock absorber mainly plays the role of reducing the upper and lower vibrations, as well as the auxiliary support role, and the frequency of abnormal noise has nothing to do with the speed of the vehicle, but has a relationship with the frequency of bumps.

According to the above knowledge, we can do a small experiment to distinguish whether it is a bearing or a shock absorber: acceleration and deceleration on a good road surface, if the abnormal noise is proportional to the speed of the vehicle, the bearing is more likely; Choose a section of road with undulations or speed bumps to test the car, if the abnormal noise follows the bumps, the shock absorber is more likely.

The above, a point that I have in mind, welcome to add corrections!

1.Turning the steering wheel in place or at low speed will make a "squeak....squeak" sound, and in severe cases, you can feel the steering wheel vibrate. 2. When driving, the tire noise becomes significantly larger, and there will be "hum..."Buzz".

3. When driving on bumpy roads or passing speed bumps, you will hear "Knock..."Knock" sound. 4. Vehicle deviation can also be caused by damage to the pressure bearing. As.

Symptoms of broken bearings: 1. Turn the steering wheel in place or at low speed.

"Squeak..."squeak" sound, and in severe cases, you can feel the steering wheel vibrate. 2. When driving, the tire noise becomes significantly larger, and there will be "hum..."Buzz". 3. When driving on bumpy roads or passing speed bumps, you will hear "Knock..."Knock" sound.

4. Vehicle deviation can also be caused by damage to the pressure bearing. How to repair: 1:

Removing the tires allows you to see the car's brake discs.

and brake calipers, remove them to see the front wheel bearings. 2: Remove the outer dust cover of the bearing with the opening, and you can see the large nut that fixes the bearing.

Remove the nut with a sleeve of 30. 3: With an 18 torx wrench.

Remove the two screws that hold the brake caliper in place and slowly remove the caliper to prevent the brake hose from breaking. 4: Remove the brake disc on the outside, if the brake disc cannot be removed, you can use two screws to screw the brake disc hole, and tighten the screws with the corresponding wrench, you can remove the brake disc.

5: The strong nut on the outside of the bearing has been removed, and the bearing can be removed by pulling it out with both hands. 6:

Install the new bearing, replace the new strong nut, after tightening the nut, rivet the edge of the nut with an opening, so that the nut is stronger, and install the dust cover. 7: Install the brake disc and brake caliper, and the bearing will be replaced this time.

Hello, the bearing you asked is used in **, I provide a car front wheel bearing bad column, I hope to help you. Hello! If the front wheel bearing is damaged, if it is not very serious, the noise will be very loud and it will make a buzzing sound after driving, which is different from the tire noise.

You can drive for half an hour, get out of the car, and touch the hub with the back of your hand where you think the bearing is damaged

Once the bearing problem is very serious, the wheel mechanism may be damaged due to bearing failure when the vehicle is driving, resulting in the wheel hub falling off and causing serious traffic accidents. Therefore, car owners must learn to check and judge whether there is a fault in the car bearing, so what are the symptoms of a broken car bearing?

1. When the vehicle is driving, the noise is too loud, and the sound of "buzzing" is scattered.

2. The vehicle deviates and the wheels are abnormal.

3. When turning the steering wheel, there is a vibration, or a "squeak" sound.

4. The body shakes and the power weakens at high speed.

5. The temperature of the hub is abnormal after driving, and the surface of the hub is hot.

If your car has any of the above conditions, please be sure to carefully check the car for bearing faults, and if you find a fault, you must repair it immediately.

The abnormal noise of the front bearing and the front shock absorber of the automobile may be different: the sound is different, the duration is different, and the abnormal noise road conditions are different.

1. The silver tone of the transcript group is different.

1. Abnormal noise of the front bearing: there will be (buzzing sound) when the vehicle is moving.

2. Abnormal sound of the front shock absorber: there will be (when the sound is sound) when the vehicle is moving.

Second, the duration is different:

1. Abnormal sound of the front bearing: the sound is continuous and becomes louder with the increase of vehicle speed.

2. Abnormal sound of the front shock absorber: the sound is intermittent and has nothing to do with the speed of the vehicle.

3. Different road conditions with abnormal noises.

1. Abnormal sound of the front bearing: the flatter the road, the more obvious it is.

2. Abnormal noise of the front shock absorber: the more bumpy the road surface, the more obvious the key banquet.

If the car bearing is damaged, the car owner will hear a continuous humming sound in the car while the car is moving, and the faster the speed, the louder the sound. The method of judging bearing damage is as follows:

Method 1: Open the window and listen to see if the sound is coming from outside the car;

Method 2: After increasing the speed, put the gear position in neutral gear to let the vehicle slide, observe whether the noise comes from the engine, if the hum does not change when coasting in neutral, it is most likely that there is a problem with the wheel bearing;

Method 3: Stop temporarily, get out of the car and check whether the temperature of the axle is normal. Touch the following four wheels with your hands, roughly feel whether their temperature is the same, if the difference is not big, you can continue to drive slowly to the pit station;

Method four: use the lift to lift the car, when there is no lift, you can use the jack to lift the wheels one by one, manpower quickly rotates the four wheels respectively, when encountering the problem of the axle, it will make a sound, and other axles are different, use this method to distinguish which axle is the problem.

Note: The worn or damaged hub bearing or hub unit of the automobile bearing will cause the vehicle to fail inappropriately and costly on the road, and even cause harm to the safety of the car owner, therefore, the car owner needs to pay attention to the use of the car bearing.

I'm here to answer your questions. The first is that the wheel of the car is damaged, and the wheel shakes when the car runs, and the shaking of the whole vehicle is aggravated, and the second is that the bearing is damaged, and there will be abnormal noise. The third, the rolling is not smooth, which leads to a drop in power.

The biggest impact is the intensification of body shake and abnormal noise. Replacement is recommended.

Automobile bearing is a general term for the category of bearings for automobiles, including automotive engine bearings, driving bearings, auxiliary electrical bearings, etc. Many categories of bearings.

The main function of the wheel bearing is to bear the load and provide precise guidance for the rotation of the wheel hub, it bears both axial and radial loads, and is a very important component. The traditional bearings for automobile wheels are composed of two sets of tapered roller bearings or ball bearings, and the bearings are installed, oiled, sealed and the clearance adjustment are carried out in the automobile production line.

Abnormal noise, large gap, hot, unbalanced, chaotic swinging.

When the shock absorber is broken, the car will make noise when it passes over speed bumps or partially bumpy roads. And there may be noise when the car is driving in that direction.

It is more troublesome to replace the shock absorbing bearing, so the labor cost is relatively high. When replacing the shock absorber bearing, the shock absorber needs to be removed, so removing the shock absorber requires removing the suspension connecting rod, so there are quite a lot of things to dismantle. After replacement, the wheel alignment should be re-aligned.

When you open the bonnet, you can see the top of the two shock absorbers, so most of them have dust covers on top of this tower. When the dust cover is opened, the flat bearings of the shock absorber can be seen.

If your car is making noise in the direction of travel, or on a bumpy road, it's most likely that the flat bearing is broken.

When using the car, it is necessary to pay attention to the lubrication of the shock absorbing bearings. The shock-absorbing bearing should be lubricated frequently, and the dust cover must be covered, otherwise it is easy to enter the dust.

Because the suspension parts need to be removed when replacing the shock absorber bearings, the wheel alignment needs to be done again after replacement. Otherwise, there may be a phenomenon of car deviation or tire misalignment.

In normal times, when passing through a part of a speed bump or a bumpy road, it is necessary to pass at a descending speed. When playing the direction, you must not kill the steering wheel. If you have one, you can straighten it. Do not drive along roads or rocks on a regular basis.
