An annoying sound resembling a squeak or a grinding sound can unbalance even the calmest driver. Screaming the doors in the car is not just acoustic discomfort, but also the first signal that the mechanisms require your attention. Ignoring this problem can lead to accelerated wear and tear of parts, corrosion and, ultimately, costly repairs or replacement of components.
The causes of extraneous sounds can be very different: from the banal drying of lubricant to the displacement of the geometry of the body. In this article, we will discuss in detail why doors creak, what tools will be needed for diagnosis and how to get rid of annoying sound on your own. The right approach to service will prolong the life of the body parts of your car.
Before you start active actions, you need to accurately determine the source of the sound. Often drivers mistakenly believe that the problem lies in the hinges, when in fact rubbed seal or lock. Accurately localizing the noise source is already half the success in the fight for silence in the cabin. Diagnostics It should be carefully and consistently conducted.
There are several reasons why car doors start to make unpleasant noises when opening or closing. Understanding the nature of noise helps you choose the right method of troubleshooting. Most often, the culprit is the friction of the metal against the metal due to the lack of lubricant.
- 🔧 Lubrication: Atmospheric precipitation and high pressure sinks gradually wash out the factory lubricant from hinges and locks.
- 🌡️ Temperature variations: A sharp change in temperature causes materials to contract or expand, which changes gaps and causes friction.
- 🚗 Body geometry: sagging of the door or shifting of hinges due to impacts or natural wear puts a strain on the mechanism.
- 🧊 Freeze.In winter, moisture in the mechanisms can crystallize, blocking the free flow of parts.
Particular attention should be paid to the sealants. Rubber elements eventually tan, lose elasticity and begin to creak when rubbing against the metal of the body. Silicone Lubricants are great at restoring the properties of rubber, but it is important not to confuse them with oils that can destroy the structure of the material. The sound source may also be a mechanism. fixator doors that require cleaning and lubrication.
For qualitative elimination of creak you will need a minimum set of tools and the right consumables. Using inappropriate means may temporarily drown out the sound, but will not solve the problem, and in some cases even make the situation worse. For example, use WD-40 As the main lubricant is a mistake, since this composition rather washes out the remnants of the old lubricant than creates a protective layer.
You will need to prepare the following materials for the work:
- 🧴 Cleaner: special spray to remove old dirt, bitumen and oxides from metal surfaces.
- 🛢️ Lubrication for hinges: thick lithium or graphite lubricant capable of withstanding high loads.
- 🧣 Silicone spray: exclusively for processing rubber seals to maintain their elasticity.
- 🧽 Mulch and brushes: for mechanical cleaning of hard-to-reach places from accumulated dirt.
Metallic rubbing parts need thick compositions that do not spread, and rubber elements - in neutral silicone impregnation. Never apply lithium lubricant to rubber sealsSince oil refining products can cause swelling and destruction of rubber, which will lead to loss of airtightness of the cabin.
☑️ Preparation for hinge lubrication
The process of lubricating door hinges is a basic procedure that every car owner should be able to perform. It is the hinges that experience the greatest load, holding the weight of the door and ensuring its free passage. Over time, the protective layer thins, and begins dry contact of the metal, giving rise to creaking.
First, you need to carefully clean the outer part of the hinges from visible dirt and dust. Use a brake cleaner or a special spray cleaner to wash dirt from the gaps between the hinges fingers. After cleaning, let the surface dry. Only then can a new layer be applied. lubricant.
Apply lubrication abundantly, trying to get into all the joints. If the design allows, the door is better removed or open as wide as possible to allow access to all rubbing surfaces. Opening and closing movements will help distribute the composition within the mechanism. Lithium lubricant It is preferable to liquid oils, as it stays in place longer and better protects against moisture.
Door seals are not only protection from noise and water, but also a frequent source of creaking, especially in the cold season. Rubber loses its properties under the influence of ultraviolet light, reagents and temperature changes. The screech occurs at the point of contact of rubber with the metal of the door or body.
To restore the silence, it is necessary to clean the seals from dust and plaque. Use a wet cloth with a soft detergent. After drying, apply a special air conditioner for rubber based silicone. This will return the material to elasticity and create a sliding layer that eliminates friction.
⚠️ Note: Do not use oil-based lubricants (solidol, litol, motor oil) for rubber seals. They cause swelling, stickiness and rapid destruction of the rubber structure, which will lead to the need for a complete replacement of seals.
If the creak persists after processing, check the density of the door adjoining. The seal may be deformed or have ruptures. In winter, the cause of the sound can be the freezing of the seal to the body, so regular processing silicone spray In autumn, it is a mandatory preventive measure.
The lock mechanism and the response part (fixer) on the body rack are also subject to intense friction. Every time the door is slammed, the metal parts hit each other. Over time, dust accumulates here, mixed with lubrication, forming an abrasive mass, which causes creaking.
To maintain the lock, it is recommended to use an aerosol cleaner to blow out old dirt from the mechanism. After purging, apply a graphite lubricant or a specialized composition for locks. Graphite is good because it does not collect dust as actively as oil lubricants, and retains its properties at low temperatures.
| The door element | Type of lubricant | Frequency of processing | Risk of error |
|---|---|---|---|
| loops | Lithium, graphite | Every 6-12 months | Use of liquid oil (flowing out quickly) |
| Sealers | Silicone spray | Once in 3-4 months | Use of oils (destroys rubber) |
| Lock and lock | Graphite, Teflon | Once a year. | Excess lubrication (attracts dust) |
| Limiter hinges | Lithium lubricant | When the squeaking occurs | Ignorance (leads to production) |
Pay attention to the door opening limiter. It is a metal bar or cable that prevents the door from opening too wide. The door and the door are also attached to the sleeves that require lubricant. Often they are the ones who make a deaf creak when opening the door to its full width.
If lubrication of all moving parts did not help eliminate sound, the problem may lie in the violation of the door adjustment. The door can sag, and then it will rub against the body or the lower part of the opening. This not only creates noise, but also makes it difficult to close.
To adjust, it is usually required to loosen the hinge bolts to the body and slightly shift the door in the desired direction. It is a delicate job requiring a helper, as the door is heavy. After displacement, the bolts are tightened, and the ease of travel and the closing density are checked. The position of the lock fixator on the central rack is also adjusted.
Sometimes creaking occurs because the door is pressed too hard against the seal. In this case, you can slightly ease the tension by changing the angle of inclination of the fixator. Be careful, though: Excessive loosening can cause the door to close the first time or start letting water and noise through while driving.
⚠️ Note: When adjusting the hinges, do not over-tighten the bolts. This can lead to the breakdown of the thread in the body or deformation of the fasteners, which will require expensive restoration of seats.
Prevention is the best way to avoid the appearance of creaks. Regular care of door mechanisms takes a little time, but maintains comfort and prolongs the life of the car. Simple habits will help you forget about annoying sounds.
Include door condition checks in your seasonal service schedule. In autumn, be sure to treat seals with silicone to prepare them for winter. In the spring, conduct an audit of hinges and locks, removing the accumulated dirt and reagents during the winter. Regularity The procedures are more important than their complexity.
Use only quality materials from proven manufacturers. Cheap lubricants can quickly dry, turn into an abrasive or wash off after the first trip in the rain. Investing in good chemistry will pay off with silence in the cabin and proper operation of the mechanisms over the years.
Frequently Asked Questions (FAQ)
Can WD-40 be used to remove the creaking of doors?
WD-40 is a great solvent and water repellent, but a poor long-term lubricant. It can temporarily remove the creak, washing out the dirt, but quickly evaporates. After its application, be sure to apply a specialized lubricant (lithium or graphite), otherwise the creak will return in a few days.
How to lubricate rubber seals so as not to creak?
For rubber seals, only silicone-based products can be used. They do not destroy rubber, give it elasticity and create a slippery layer. Oils, solidols and lithium lubricants can not be used, as they will lead to swelling and destruction of rubber.
Why does the door only creak in winter?
In winter, the cause is often frozen moisture in the mechanisms or loss of elasticity of rubber seals in the cold. Also, the cold metal is compressed, changing the gaps. Processing with silicone in the fall and using frost-resistant lubricants helps avoid this problem.
How often should the car door hinges be lubricated?
It is recommended to carry out preventive lubrication of hinges and locks at least once a year or every 15-20 thousand kilometers of run. If you often drive off-road or wash your car under high pressure, the interval should be reduced to once every six months.
