There is a chirping sound in the car driving, and the chassis creaks and creaks

Car noise bothers many friends, especially after a few years of vehicle use, there may be various abnormal noise problems inside and outside the car. Recently, a friend said that there is a twitter sound in his car, so how should we solve this kind of problem when it occurs? Let's take a look!

There is a sound of chirping in the carIn fact, there are many reasons that can cause a vehicle to rattle, the most common of which is the abnormal noise of the interior trim and the abnormal sound of the chassis. When the vehicle is used for several years, the cushioning rubber parts of the chassis begin to age or crack, and the aging of the rubber parts means that the chassis parts of the vehicle are not effectively buffered, and the chassis will have various abnormal noises when driving on uneven roads. Secondly, the abnormal sound of the interior trim is mainly caused by the installation of the trim plate is not in place, if you have ever removed the interior trim for maintenance, it greatly increases the probability of abnormal noise in the interior.

In general, when there is a squeak in a vehicle, we need to find the root cause of the squeak first, and then prescribe the right medicine.

What's going on with the chassis creakingThe squeaky sound of the chassis is likely to be caused by problems such as aging shock absorbers, ball joint wear, plane bearings, and control arm cushioning rubber. When the rubber parts of the vehicle chassis deteriorate, we can only solve it by replacing them. If the shock leak is too serious, it will not be worth repairing, and it can only be solved by replacement.

There are many reasons for abnormal chassis noise, and the specific situation can only be judged depending on the actual situation.

Due to the abnormal contact and friction between the brake disc and the brake pad, according to the analysis of previous maintenance cases, most of the cases are caused by the following reasons, one may be due to the phenomenon of poor return of the brake cylinder, resulting in the brake disc and the brake pad are always in slight friction, and the other may be caused by the hard spots on the surface of the brake pad or the foreign matter such as fine sand particles between the brake disc and the brake pad.

Maintenance suggestions: It is recommended to go to a special repair shop to check whether the brake cylinder has a poor return, or to remove the brake pads and polish the friction surface, which will generally be significantly improved.

The balance bar is also called the anti-roll bar and the stabilizer bar, and there are two buckles on the balance bar, and the buckle is the rubber sleeve of the balance bar. It is cold in winter and hot in summer, and with the erosion of soil and dust, it will become harder and harder after aging. As a result, when the vehicle passes over uneven road surfaces, the height of the left and right wheels is inconsistent, and a creaking sound will occur.

Solution: Replace it. This part is not expensive, however, it is cumbersome to replace, and most people are reluctant to replace it.

This thing has no impact on safety, so if it doesn't work, just put up with it. Another way is to buy WD40 (high-efficiency silicone lubricant), but I am not sure how effective it is, and it is said that I can only manage it for a month.

Summary. Then you check the right rear pressure bearing and top rubber to see if the right rear hub bearing clearance and half shaft clearance are suitable.

What is the reason for the creaking sound of the chassis when the car is moving?

Hello, happy to answer your questions.

Hello, in this case, the main check is whether there is a problem with the hub bearing and half shaft clearance, as well as the shock absorber, pressure bearing and top rubber.

The pickup truck creaked as soon as it shook.

Where do you feel the sound?

Rear right shock absorber.

Then you check the right rear pressure bearing and top rubber to see if the right rear hub bearing clearance and half shaft clearance are suitable.

Ok thanks!

You're welcome.

The reasons for the creaking sound of the automobile chassis: 1. The rubber sleeve of the balance bar is corroded or aging; 2. Brake pads are damaged; 3. The connection between the suspension and the shock absorber fails; 4. Abnormal sound of wheel bearings; 5. Deformation of shock absorbing spring; 6. Aging or wear of shock absorbing pressure bearings.

If the problem is still there, you can disassemble and check the meshing clearance between the differential gear and the reducer gear, the preload of the reducer tapered driving gear bearing and the contact trace of the reducer gear to eliminate abnormal noise.

There are many reasons for this problem caused by the creaking sound of the car chassis, including fastening, such as the lower swing arm and brake of the car will have a sound when passing through the uneven road, which is normal, There is also the brake locking, There will also be abnormal noise, the rear axle and the body pay attention to it, the rear sliding column to take a look, whether the buffer block falls off and the exhaust pipe will also produce abnormal noise, and then there is the interference sound, this sound is generally the design of the question, There are several mounts of the engine connected to the body to see if there are signs of loosening, and if there is a new one.

Inspection method for aging and loosening of balance rod opening glue:

Raise the car, grab the balance bar with your hand and shake it vigorously, normally it can't be shaken, if it is loose, you need to replace the balance bar opening glue. (Equalizer bar, also known as anti-roll bar), equalizer rod boom ball head aging. It is necessary to remove the tire and observe whether the rubber at the ball joint of the boom is aging and cracking.

If it is aging, it needs to be replaced directly.
