When the car stops and starts, there is a sound on the right rear wheel, and I think 25

Hello, this should be caused by a shock absorber problem, you can take a look and then check if there is a problem with the tire bearing

This is mainly the sound of the friction between the brake disc and the brake pad, mainly the rust on the brake disc, so it will cause the sound of abnormal noise, it is recommended that you remove the brake pad and polish it with coarse sandpaper.

Hello, you see if the brake disc has rust, if there is embroidery, this is a normal phenomenon, there is no problem.

It seems that this situation is generally caused by the poor return of the brake cylinder, so it is recommended that you go to the repair shop or 4S shop to check the brake cylinder, and at the same time check whether the brake pads are worn.

If the vehicle is parked for one night or a few days and there is an abnormal noise at the starting time, it is normal for the brake pads and brake discs to be worn, and it is no problem to check that the brake pads are not obviously worn and grooved.

Hello, this is generally because of the problem of the brake disc of the car, it is estimated that it is eccentric grinding can be checked.

Hello, this may be caused by the hard material of the brake pads, mine is like this, every day the first few brakes have movement.

If it is parked for too long, there is no problem with the rust of the brakes, and the rust can be cleaned after a while.

Hello, put it for a long time, it is possible that the brake pads and brake discs are sticky. In addition, it is caused by rusty brake discs.

Hello! You check if the brake disc has small stones or something, and if so, clean it up.

If there is an abnormal sound on the right rear wheel when parking and starting, it is recommended to check whether it is caused by a brake problem

It is possible that there are several scenarios:

1. Metal hard spots appear on the brake pads. There will be some fine metal particles inside the brake pads, and the light pressure on the brakes will make a sharp and piercing sound, this kind of problem can be slammed a few feet of the brake or the brake pads can be removed and re-polished, or replaced with better brake pads.

2. The brake disc is seriously worn。The wear of the brake disc will form a deep groove around the disc, and the friction between the brake pad and the edge of the groove will produce abnormal noise. If the groove is not particularly deep, it can be solved by grinding the edge of the brake pad to avoid the friction between the brake pad and the edge of the groove, and if the groove is already deep, it is recommended to replace the brake disc.

It is generally recommended to replace the brake disc once after changing the brake pads twice.

3. The assembly problem of brake pads。Try to reinstall the brake pads and apply butter or special lubricating oil to the connection between the brake pads and the brake caliper. It is also possible that the brake pads are installed in reverse and can be reassembled.

Especially car owners who have replaced brake pads at roadside stalls should pay more attention to this.

4. There is a harsh abnormal sound when reversing and stepping on the brakes. Considering that most of the working time of the brakes is in the process of driving forward, the brake pads wear in one direction for a long time will cause some burrs on the reversing surface, and the friction between the burrs and the brake disc will produce abnormal noise. In this case, you can remove and polish the brake pads, or you can replace them with better brake pads.

5. There are small pebbles or water films between the brake discs. For example, if you are walking on a gravel road, in windy and sandy weather, or just after washing your car, just step on the brakes a few more times, or remove small pebbles.

There may be several reasons for this:

1. The clutch sounds;

2. The transmission shaft supports the bearing;

3. Abnormal sound of drive axle;

4. Abnormal noise of the differential;

5. Abnormal tire noise;

6. A certain part of the vehicle loosens the vehicle resonance.

It depends on what the sound and the sound ** can be judged, it is recommended to go to 4S or a repair shop to check.

This is caused by the large gap between the brake pads and the brake cylinder. In this case, you need to go to a nearby repair shop to check it, it may be the normal wear of the brake pads, or it may be a place where there is damage to the suspension. The brakes are accomplished by the intense friction between the brake pads and the brake drums.

When driving in water, the wheels are almost immersed in water, leaving a layer of water film between the brake pads and the brake drum, just like applying lubricating oil, so that the friction between the brake pads and the brake drum is reduced, and the car cannot be controlled to stop, and the water in the drum is not easy to disperse. This phenomenon of brake failure comes very quickly, after walking away from the water while stepping on the brakes, several times in a row, the water droplets between the brake pads and the brake drum will be wiped off, at the same time, the heat generated by the friction will dry it, so that the brakes will quickly return to the original sensitivity. This kind of brake failure is almost impossible for cars with disc brake systems, because the brake pads are small and the periphery of the disc is completely exposed, leaving no water droplets.

Due to the centrifugal force when the wheels rotate, the water droplets on the disc are automatically dissipated without affecting the function of the braking system. Many small cars that are usually used have front disc and rear drum brakes, so some brakes fail after wading, and some brakes will weaken a lot.

It is very likely that some bolts in the connection of the engine are loose and can be checked by a nearby repair shop, or it may be a noise from the wear of the brake pads, and there may be damage to the suspension.

This doesn't have much of an impact, and it's likely just a sound of inertia. If it's too loud, you'll want to stop on the side of the road to check for a flat tire.

The rattling of the right rear wheel of the car, if it is only when passing over a pothole, it should be a problem with the suspension system. The owner can check whether the upper and lower pads of the spring are aging, causing the spring to collide with the metal support and make a sound. Also check the degree of deterioration of the rubber parts at the joints of the various connecting rods of the suspension.

It is also necessary to check whether there is oil seepage after the shock absorption, if there is oil seepage after the shock absorption, it has not played the role of shock absorption. Check whether the rubber sleeve of the screws fixed up and down the shock absorber is loose, if so, it needs to be replaced or found a way to fix it.

Check whether the screws of the chassis, rear axle, tires and other screws are loose, and check and tighten all the screws that may cause abnormal noise. If the dust cover becomes stiff and long, the excess dust cover needs to be cut off due to the sound generated by friction.

The cause of the failure of the shock absorber will make a noise in actual use.

If the shock absorber collides with leaf springs, frames or shafts, the rubber pad is damaged or falls off, the shock absorber dust cylinder is deformed, and the oil is insufficient, the cause should be identified and repaired.

The owner can drive the car to stop after driving 10km on the road surface with poor road conditions, touch the shock absorber shell with his hands, if it is not hot enough, it means that there is no resistance inside the shock absorber, and the shock absorber does not work. Appropriate lubricating oil can be added, and then the test is carried out, if the shell is hot, it is a lack of oil inside the shock absorber, and sufficient oil should be added; Otherwise, the shock absorber is out of order.

Mine is also clucking low-speed sound running fast not loud for more than half a month went to the 4s shop and did not find the problem The repairman tightened the screws of the chassis and the rear axle The problem was still not solved Later, I bought the brake pads on the Internet and changed them myself In the process of changing, I found out that the reason was that the tire screws were loose I hope it can help you.

Check the tires first for problems.

This phenomenon can be caused by abnormal wear of the tire, or by nails or stones sticking to the tire, or by foreign objects (nails, stones, etc.). Stepping on the countertop may make the tires make abnormal noise during driving, so it is recommended to go to a tire shop to check.

If there are intermittent gurgling or knocking sounds when cornering, climbing, or walking poorly, it may be a broken cage and shock absorber outside the left front half shaft or a worn chassis suspension ball joint and bushing. Go to the repair shop as soon as possible to check and eliminate potential safety hazards.

Test process: Lift the vehicle with a lift and check whether the screws and rubber parts in the front of the chassis are loose. Remove the front shock absorber to check if the shock absorber is in good condition, remove the front wheel and check the front wheel bearing.

Check that the front-wheel drive half-shaft is not loose. Finally, determine the cause of the failure and replace the parts. No matter what the cause of the abnormal noise of the front wheels of the car, it is best to go to the repair shop to find a professional repairman for inspection and repair to avoid safety accidents.

Due to the abnormal noise of the brakes, the brake pads of the front wheels may wear out. It is recommended that you check the brake pads of the front wheels. If the thickness of the brake pads is less than 3 mm, they need to be replaced. When replacing brake pads, be sure to lubricate the screws of the brake cylinder.

According to the structural form, automobile frames can be divided into side beam frames, middle beam frames, integral frames and beamless frames. Many cars and coaches do not have a separate frame, but instead attach the main components to the body, known as a load-bearing body. The underbody of this structure is reinforced by longitudinal members and beams.

The body is rigid and lightweight, but the manufacturing requirements are high.

It is difficult for ordinary car owners to distinguish between faulty abnormal noise and reasonable abnormal noise. When we went to the repair shop to inspect the squeak and squeak vehicles, only about 20% of the vehicles were really problematic. There is definitely a difference in the sound of a turbocharged engine and a naturally aspirated engine.

Models with engine guards installed.

If you hear a noticeable buzzing sound while driving, the faster you go, the louder it gets, and it's likely that the left front hub bearing is broken. To solve the abnormal noise, it is best to drive to the repair shop and let the maintenance master actually check it.

This phenomenon may be caused by abnormal wear of the tire, either the tire has nails, or it is stuck with stones, or there are foreign objects on the tread, which may make the tire make abnormal noise during driving, and it is recommended to go to the tire shop for inspection.

It may be because of small stones stuck in the tire, or it may be that the tire has skidding.

It may be that the wheel alignment is inaccurate, or the tires are causing some wear, or it may be the noise caused by the bearings.

Is it that the handbrake behind you is pulled too tightly, and then there is water on that rear wheel.

Check the brake pads, some brake pads may have abnormal noise in the later stage.

Summary. Hello. I've found the answer for you and I'm back, and the correct explanation is as follows Oh The squeak of the rear wheels when the car first starts is caused by a variety of factors, common ones may include:

1. Brake disc The surface of the brake drum is rusty: the surface of the brake disc or brake drum may rust when the parking time is long, and when the brake pedal is pressed, the friction will make the rusty surface rub and make a squeaky sound. 2. Brake pads Brake drum wear:

A squeaking sound may also occur if the brake pads or brake drum have been worn to a certain extent. 3 Rear wheel bearing problem: If there is a problem with the rear wheel bearing, it will also squeak.

If the sound is loud or lasts for a long time, it is recommended to go to the repair shop for inspection in time. 4 Loose rear brakes: Loose rear brakes may cause poor friction of brake components, resulting in a squeaky sound.

Tell me the details and I'll help you analyze it!

When the car first started, there was a sparse sound on the rear wheels, and after driving for a while, it disappeared for a while.

Hello. I'll find the answer for you and come back, and I'll answer Lu Zhaozheng as follows Oh The squeak of the rear wheel when the car just started is caused by a variety of factors, and the common ones may include: 1 brake disc The surface of the brake drum is rusty:

When the brake pedal is pressed down, the friction will cause the rusty surface to squeak when the brake disc or brake drum is parked for a long time. 2 Brake pads Worn brake drums: If the brake pads or brake drums have been worn to a certain extent, there may also be a squeak.

3 Rear wheel bearing problem: If there is a problem with the rear wheel bearing, it will also squeak. If the sound is loud or lasts for a long time, it is recommended to go to the repair shop for inspection in time.

4 Loose rear brakes: Loose rear brakes may cause poor friction of brake components, resulting in a squeaky sound.

You don't need to apply the brakes at all, just when you start, you can hear this sound after walking for a few minutes, and it disappears after a while.

Insufficient engine belt tension: The belt may hiss when the engine starts to grind. If the sound fades after a few minutes, it may be that the belt gradually warms up after activation, and then slowly regains tension.

So what should be done.

But the part that makes the noise is on the tire.

Adjust belt tensioning: Insufficient belt tensioning may be caused by belt tensioner failure or loosening. In a professional auto repair shop, the problem of loose belts can be solved by adjusting the belt tensioner or replacing the belt.

Replace the belt: If the belt has been worn or aged and can no longer return to normal tension, then it needs to be replaced with a new belt. Regular maintenance:

Regular car maintenance, especially the replacement of the engine belt cycle must be followed, in order to maintain the tension and service life of the belt.

If it is on the tire, it is caused by uneven tire tread wear, insufficient tire pressure, tire wear, tire breakage, etc.

There are several possible causes:

1. The brake disc is mixed with fine stones, which leads to abnormal friction during driving.

2. Caused by abnormal wear of tire bearings, due to lack of oil or fatigue wear.

3. The main material of the brake pad is heavy metal, and there will be metal hard spots, which may make abnormal noises during driving.

4. The back plate of the brake pad is metal, and there will be abnormal noise when running.

5. If the brake pad baffle is deformed, it will rub against the rotating tires.
