Screaming the car doors is not just an annoying factor that spoils the pleasure of driving, but also a signal that the mechanism requires attention. The sound of rubbing metal or rubbing rubber can occur suddenly, making the driver nervous and distracted from the road. The source of noise is often hinges, opening limiters, locks or rubber seals that have lost elasticity.
To effectively eliminate the problem, it is necessary to accurately determine the source of the sound and choose the right lubricant. The use of inappropriate compositions can lead to rapid wear of parts or even damage to the paint coating of the body. In this article, we'll look at this. How to remove the car doors from the creakTo forget about the strange sounds for a long time.
There are many folk methods and professional solutions, each of which has its advantages and disadvantages. Some prefer time-tested graphite lubricant, others choose modern aerosols based on silicone or Teflon. The choice depends on the specific friction pair and the vehicle operating conditions.
Diagnostics of the source of the creak
Before grabbing a can of lubricant, it is necessary to precisely localize the problem. Script can be published in different points: in the area of loops, where the metal rubs against the metal, or in the area of rubber seals that stick to the body in the cold or dry out in the sun. Sometimes the sound comes from the lock mechanism or the interior lining of the door.
For accurate diagnosis, open the door and swing it up and down and back and forth. If you hear the creak when the door is moving in hinges, then the problem is hub-sleeves Or the fingers themselves. Often the source of noise is precisely the door opening limiter, where the plastic roller rubs against the metal groove.
If the sound appears at the time of closing or opening in the cold, most likely, it is in rubber seals. They can rub against the body or freeze. It is also worth checking the interior of the door: a weakened window or elements of internal wiring that come into contact with the metal frame can creak.
⚠️ Never use WD-40 as the main lubricant for rubbing door mechanisms. It's beautiful. solvent It's a moisture dislodge, but it quickly washes out the remnants of the old lubricant and evaporates, leaving the metal on dry, which accelerates wear.
Selection of lubricant
The automotive chemical market offers a wide range of products, and the choice depends on what part to process. Metal hinges and locks require thick, resistant to washing compositions that can withstand high loads. For rubber and plastic, special means are needed that do not destroy the structure of the material.
One of the best options for loops is considered lithium-lubricant. It has excellent adhesion, is not afraid of water and retains its properties in a wide range of temperatures. Silicone sprays are ideal for processing seals, as they create an elastic film that prevents freezing and friction.
For locks and larvae, graphite lubricants or Teflon aerosols are best suited. Graphite does not collect dust as actively as oil, and Teflon creates a slippery dry coating. It is important to avoid oil on the paint coating, as some aggressive components can damage the varnish.
Can I use solidol or litol?
Use ordinary solidol or litol can only be as a last resort. These lubricants tend to thicken in the cold and stuff dust and sand into themselves, turning into an abrasive mass. It is better to buy a specialized spray for loops that does not flow and lasts longer.
Handling of hinges and restraints
The process of lubricating the hinges requires accuracy and preparation. First, you need to clean the surface of dirt, old lubricant and corrosion. You can use a brake cleaner or the same WD-40, but after cleaning, be sure to wipe the parts dry before applying a new composition.
Apply the lubrication directly to the axis of the loop and into the gaps between the moving parts. If the design allows, it is advisable to develop the door a little, opening and closing it several times so that the lubricant penetrates deep into the bushings. Remove the excess lubricant immediately with the rags.
Pay special attention to the door opening limiter. It is in this node that metal ringing or a deaf creak often occurs. Plenty lubricate the roller mechanism and the response part on the body. Regular processing of this area will prolong the life of plastic and prevent backlash of the door.
☑️ Checklist of hinge lubrication
After the procedure, the door should walk softly and silently. If the creak has been preserved, the hinge finger itself may have worn out or a production appeared in the hole, which will require more serious repairs with the replacement of parts.
Care for rubber seals
Rubber seals are the first barrier to noise, water and dust in the interior of the car. Over time, rubber loses plasticizers, hardens and begins to creak when rubbing against the metal of the body. This problem is especially relevant in winter, when seals can freeze to the door.
To restore elasticity and eliminate creak, use silicone lubricant. It does not allow rubber to dry out, protects against ultraviolet light and creates a slippery layer. Apply the composition is best on a clean and dry surface, evenly distributing it with a soft cloth or sponge.
Do not forget to process seals not only along the perimeter of the door, but also on the central pillar of the body, as well as a glass sealer. Regular care, especially before the winter season and after washing, will avoid unpleasant sounds and prolong the life of rubber elements.
Before lubricating the seals, wipe them with an alcohol solution or a special rubber cleaner to remove silicone plaque and dirt. This will ensure better penetration of lubricant into the pores of the material.
| Type of lubricant | What's the point? | Advantages | Deficiencies |
|---|---|---|---|
| Lithium lubricant | Metal hinges, hinges | Durability, protection against corrosion | Maybe get your clothes dirty. |
| Silicone spray | Rubber seals, plastic | Does not harm rubber, repels water | It is fast and requires frequent updates. |
| Graphite lubrication | Locks, maggots. | Does not collect dust, works at low temperatures | Smears everything black. |
| Teflon spray | Locks, guides | Dry film, not sticking to dirt | High price, you need an accurate applicator |
Lubrication of door locks and larvae
Door locks are subjected to constant mechanical stress and the influence of the external environment. Dust, moisture and temperature changes lead to the fact that the mechanism begins to jam or make unpleasant sounds when opening and closing.
For lubricating locks, it is best to use Teflon (PTFE) sprays or specialized graphite compounds. Oil lubricants in this case are not recommended, since they thicken over time, collect all street dust and turn into an abrasive gruel, which can completely jam the mechanism.
When processing the larva of the lock, use a thin tube-applicator, complete with a balloon. Inject a small amount of lubricant inside the larva, insert the key and turn it several times so that the composition is distributed across all pins and springs.
⚠️ Warning: Avoid grease on the lock tongue and the response bar on the body rack in large quantities. The excess can drip on clothes when landing in the car or spread over the varnish, spoiling it.
Removing creaks inside the door
If the external treatment did not help, and the sound is heard from the inside of the door card, you will have to remove the skin. Inside the door, there are many rubbing parts: a window lifter, lock drive thrust, wires that can touch the metal.
Often creaks the mechanism of the window lifter itself. Its guides and cables require lubrication with a specialized composition, often it is a specialty. lithium-grease. It’s also worth checking if the wires or tractions are dangling in their plastic clips. Soft materials such as squeaking and squeaking can be used to eliminate knocking. antiseptic (madeline) or porous ribbon.
Wrap the contact points of metal tractions with plastic or metal body soft material. This will eliminate direct contact and remove the ring. Before assembling the door, make sure that all fasteners are tightened, and the skin itself does not have cracks in the places where the pistons are attached.
The screeching inside the door is often caused by the vibration of loose elements. High-quality noise and vibration insulation when removed skin will solve the problem forever.
Frequently Asked Questions (FAQ)
How often should the car doors be lubricated?
Preventive lubrication of loops and seals is recommended at least once a year, preferably before the onset of the winter period. If the car is operated in harsh conditions (dust, dirt, frequent washing), the interval should be reduced to 6 months.
Can I use engine oil for the hinges?
Using conventional motor or transmission oil is highly undesirable. It is too liquid, quickly flows out of the friction zone, drains onto the paint coating and actively collects dust, which ultimately leads to accelerated wear of the mechanism.
Why are the new doors creaking?
The screeching of new doors is often caused by the fact that the parts have not yet been rubbed together, or the factory has saved on the amount of lubrication. Also, the reason may be too tight adjustment of hinges or locks, requiring adjustment.
How to lubricate the loops, if there are no special tools at hand?
In an emergency situation, you can use a piece of soap or paraffin (candle), rubbing rubbing surfaces with them. This will give a temporary effect and remove the creak before buying a proper-lubricant. However, for a long time such funds are not kept and washed away with water.
