Does anyone know about the sedan Focus s abnormal noise under the car?

Hello, when driving normally, or when it is bumpy, thank you.

Loose chassis generally occurs in older cars, when the car is driving in bad road conditions, the steering wheel will feel unstable, the bottom of the car will also come out of the abnormal sound, usually the old driver can feel the overall a little loose, when encountering such a situation, it means that the chassis may be loose, and the reasons for this situation are divided into several, only by understanding the reasons, can we better prevent this problem from happening.

The first reason is the aging of rubber parts, we all know that the elasticity of rubber is particularly good, which can buffer the friction between parts and reduce noise at the same time. However, this kind of thing has a lifespan, and it will age after a long time, and the elasticity is not as good as before, so the buffering capacity will decrease, resulting in abnormal noise in each part, so it is necessary to check these rubber parts regularly and replace them in time.

The second possibility is the reason for the shock absorber, the main role of this part is to inhibit **, when the car is driving in the dustpan section, it will have an impact with the road surface, and the shock absorber can well ensure the smoothness of the car, if the shock absorber is damaged, there will be a scoop phenomenon, so that the chassis is loose, so usually check the shock absorber, if there is a leakage to repair in time.

The third is the clearance of the parts, that is to say, the ball head may be loose, this part is like the joint of the human body, if the ball head is loose, there will be a large gap between the lever and other connected parts, if the gap is too large, when crossing some dustpan roads, the screws between the subframe and the suspension will be loose, then the chassis will become loose, so usually check these two parts.

Thank you for adopting.

Check the transparent plastic cover of the reading lamp, buckle it down and paste some double-sided tape and then install it, I encountered an abnormal noise here, looking for more than a month, I always thought it was a pillar, the abnormal sound in the car was reflected, and it was difficult to distinguish the position of the driver's seat.

Here's what causes the squeak of the classic Focus chassis:

Disc brake abnormal sound:

When the vehicle is driving at a low and pure speed on a flat road, it makes an intermittent, irregular "rattle" sound at the axle. Reason: This is because the brake shoe support plate, shock absorbing spring or guide plate of the disc brake is damaged, deformed, and the wide socks fall off, which increases the gap between the brake shoe and the caliper support frame, and makes a sound when colliding with each other.

You can go to the repair shop to repair the deformed parts and replace the parts that have been removed.

Squeak characteristics of the front suspension ball joint:

When the vehicle is driving at low speed on uneven roads, the front axle makes a non-stop "click" sound. The worse the quality of the road surface, the louder the noise, and the noise will intensify as the speed of the vehicle increases. Original Trigger:

The gap between the ball head and the ball head seat becomes larger, and the loosening is serious. Because the ball seat is a sealed structure and cannot be disassembled, in this case it can only be replaced in a repair shop.

Abnormal noise characteristics of the front wheel shock absorbers:

On flat roads, a slight "cooing" sound in front of the vehicle can be heard, which is intensified when making sharp turns. Reason: The vehicle usually drives in poor road conditions and improper maintenance, resulting in oil leakage and damage to the shock absorber. This situation should be repaired or replaced depending on the severity of the damage.

Millions of car purchase subsidies.

I bought a hatchback version of the Focus, and the handling and power can be satisfied in all aspects, but I can't stand the abnormal noise of this engine! When accelerating, the engine noise came from the cabin whining sound, which was particularly obvious, and the ** sound could not be covered, I want to ask if this is normal? Do you have one?

I bought the Taiwan hatchback version of the Focus ( check price |Detailed explanation of the model), the handling and power can be satisfied in all aspects, but I can't stand the abnormal noise of this engine! When accelerating, the engine noise came from the cabin whining sound, which was particularly obvious, and the ** sound could not be covered, I want to ask if this is normal? Do you have one?

What displacement did you buy? If it is, it is normal, because the new generation of Focus uses a three-cylinder engine. In the colleague of saving fuel consumption, because it is the defect of the asymmetry of the three-cylinder engine, the engine noise is too loud when accelerating.

Engine noise can be roughly divided into engine noise during cold start, engine noise during rapid acceleration, and engine noise at idle. 1. Abnormal noise caused by aging or loosening of the machine foot pad. The foot pad, also known as the chicken paw pad and the tripod, is generally installed in the middle of the engine and the body, connecting the body and the engine, and playing the role of fixing the engine.

And its most important role is to play the effect of cushioning and shock absorption. Once the foot pad is aged or loose, the engine shakes badly, from the The most ** Ford Focus This engine is a three-cylinder engine, in fact, I think what you hear should not be an abnormal noise, or the unique sound of the three-cylinder engine, so I don't think there is any need to make a fuss, after all, I bought it. @2019
