The screeching of doors, tight stroke and the appearance of rust on the canopies is not just a minor nuisance, but the first signal that opening-piece It requires urgent attention. Moisture, road dust and temperature swings quickly wash out the factory preservative, leaving rubbing metal vapors one-on-one with an aggressive environment. If you ignore the problem at an early stage, you can encounter sagging doors that will require not just lubrication, and complex adjustment or even replacement of nodes.
Properly selected lubricant creates a protective film that not only reduces friction, but also displaces water, preventing corrosion. However, the modern market offers dozens of options: from classic solidol to high-tech. PTFE sprays and graphite powders. An error in the choice can lead to the fact that the composition will dry, collect abrasive dust or, conversely, will be too liquid for heavy metal doors.
In this article, we will discuss in detail how to better handle carports depending on the season and condition of the car. You will learn about the properties of various materials, see a comparative table and get step-by-step instructions that will help prolong the life of the body elements of your car.
Why Doorways Crack and RustThe main cause of the occurrence of extraneous sounds and difficulty walking lies in the destruction of the protective layer. Factory lubricant laid down during assembly, over time loses its properties under the influence of ultraviolet and reactive reagents, which are sprinkled on roads in winter. When tribological layer thinning, begins direct contact of metal surfaces, which gives rise to a characteristic creak.
In addition, the design of the loop is such that moisture inevitably accumulates in the gaps between the finger and the bushing. If not used water-resistant composition with high anti-corrosion propertiesoxidation begins inside the mechanism. Rust acts as an abrasive, accelerating wear and increasing backlashes, which ultimately leads to sagging of the door and difficulties with closing it.
The situation is aggravated in winter, when snow falls into the hinge, which melts from the heat of the engine or garage, and then freezes. The ice crust blocks movement, and an attempt to sharply open the door can lead to breakage of fasteners or deformation of the canopy itself. That is why seasonal maintenance is a critical stage of body care.
⚠️ Attention: Never force yourself to open a closed door. This is guaranteed to lead to deformation of the hinges or damage to the seals. First, you need to carefully warm the joint with warm air or use a defrosting agent.
Criteria for choosing the perfect lubricantWhen choosing a composition, it is necessary to focus on the operating conditions of a particular car. For urban cars that rarely leave paved roads, the requirements are the same, and for SUVs that regularly drive into the mud and fords, completely different. The key parameter here is adhesion The ability of the material to be held on vertical and horizontal surfaces under the influence of centrifugal forces and water.
The second important factor is the temperature range. Lubricant should not thicken in severe frosts, turning into paraffin, and should not drain like water in the summer heat. The optimal range is from -40 ° C to +150 ° C, which allows the composition to maintain elasticity in any climatic zones. It is also worth paying attention to compatibility with rubber and plastic, since often the lubricant falls on the adjacent elements.
There is a common misconception that the thicker the lubricant, the better it is. In fact, excessively viscous compositions can prevent normal spreading into narrow gaps between the finger and the hinge. The result is a “dry” friction effect in the depths of the mechanism, while everything looks lubricated from the outside. Therefore penetrativeness often more important than density.
Overview of popular types of lubricantsThe automotive chemicals market offers several major product categories, each with its own advantages and disadvantages. Understanding the chemical basis will help you make an informed choice and not overpay for unnecessary functions.
- 🛢️ Lithium lubricants: The classic version, which has excellent water repellent properties and high mechanical stability. They hold well on metal, but can be washed off with prolonged contact with water under pressure.
- 🌡️ Copper and ceramic pastes: Designed for extreme temperatures. They do not burn out or melt, creating a durable dry layer. Ideal for hinges subject to heavy heat, but have a high price.
- 🧴 Silicone sprays: They are perfectly penetrated into hard-to-reach places and are safe for rubber seals. However, they create a slippery film that can quickly collect dust, turning into an abrasive gruel.
- ⚫ Graphite powders and sprays: Create a dry sliding coating, to which dirt does not stick. These are excellent choices for heavy dust conditions, but they require a perfectly clean surface before application.
Separately, it is worth mentioning universal lubricants of the WD-40 type. It is important to understand that the classic “showman” is first and foremost. solventIt's not a lubricant. It will perfectly clean the loop of old dirt and rust, but after it is drying, the friction may even intensify. Use it only as a preparatory step before applying the main lubricant.
Why can’t you use motor oil?
Motor oil is too liquid for open loop mechanisms. It quickly drains, takes with it the remains of the factory lubricant and actively collects road dust, turning into an abrasive paste that accelerates wear of the bushings.
Comparative table of lubricant characteristicsTo simplify the choice, let’s bring the main parameters of popular types of lubricants into a single table. This will help you quickly navigate depending on your priorities: durability, price or water protection.
| Type of lubricant | Water resistance | Temperature regime | Resistance to dust | Durability |
|---|---|---|---|---|
| Lithium (white) | Tall. | -30 to +120°C | Medium (sticky) | Tall. |
| Copper paste | Very high. | -50 to +300°C | Tall (not sticky) | Very high. |
| Silicone spray | Medium | -40 to +200°C | Low (attracts) | Low. |
| Graphite spray | Medium | -20 to +150°C | Very high. | Medium |
| solidol | Tall. | -30 to +70°C | Medium | Medium |
As you can see from the table, copperpaste They are advantageous in most areas, but their application often requires more careful surface preparation. Lithium lubricants remain the middle ground for most drivers, combining affordability and good performance. Silicone is better to save for lubrication of rubber seals of doors, where it shows itself in the best way.
Before buying a spray can, be sure to check the presence of a spray tube in the kit. Without it, it is impossible to qualitatively process the inner cavities of the loop, and you just splash the body around.
Technology of correct processing of hingesThe quality of the lubricant depends on the preparation of the surface. Applying a new composition over the old dirt, rust and oxides will not give any effect - the mechanism will continue to creak and wear out. The process should be gradual and thorough.
First, you need to open the door and access the hinges. If the door sags and touches the body, it may need temporary fixation or lining of a wooden bar to relieve the load from the canopies. Then we take the brake cleaner. carbclinic Or the same WD-40 and wash the hinges abundantly.
☑️ Loop lubrication algorithm
After cleaning, let the surface dry. Make sure there is no solvent left in the gaps. Now you can apply the basic lubricant. If you use a spray, use a tube to direct the jet directly into the gap between the finger and the loop body. When using thick pastes or lithium, it is convenient to use a medical syringe or a special syringe oil.
It is important to lubricate the loop from all sides, scrolling the door back and forth so that the composition is distributed throughout the working surface. Do not spare the material, but also do not allow it to flow onto the paint coating of the body. Excess immediately remove the rags so that they do not turn into a magnet for dust.
⚠️ Attention: Avoid getting aggressive cleaners and some types of lubricants on the paint coating (LAC) and plastic elements of the cabin. Many chemical compounds can dissolve paint or leave indelible matte stains on plastic.
Typical errors in the maintenance of canopiesEven experienced motorists sometimes make mistakes that negate all care efforts. One of the most common is the use of graphite lubricant over lithium or vice versa. Mixing substances of different chemical composition can lead to the formation of solid lumps or, conversely, to complete liquefaction of the mixture, which will accelerate the leaching of protection.
Another common mistake is lubricating only the visible part of the loop. Many people spray the spray outside, believing the task is completed. However, the main wear and tear occurs inside where the finger enters the bushing. Without the penetration of lubricant into this knot, the external gloss will not save from creaking. We need to ensure that the fresh lineup comes out of all gaps.
The main secret of the longevity of loops is regularity. It is enough to process them once a year, before the winter season, to forget about creaking and corrosion for many years.
Ignoring the state of seals also indirectly affects the loops. If the rubber seal of the door is blown or torn, much more water and dirt gets into the cabin and on the hinges. Therefore, maintenance of canopies should go in combination with the verification and siliconization of rubber bands.
Questions and Answers (FAQ)
How often should the car’s door hinges be lubricated?
Optimal frequency - once a year, preferably in late autumn before the start of the winter season. If you operate a car in harsh conditions (off-road, seaside, strong reagents), the frequency can be increased up to twice a year.
Can you lubricate the loops with ordinary motor oil?
It's not recommended. Motor oil is too liquid, does not have the necessary antifriction properties for rolling/slip friction units and will quickly wash away with water, leaving the metal without protection.
What to do if the door has already started to sag?
You can't do with a lubricant alone. It is necessary to check the tightening of the hinge bolts to the body and door. If the bolts are tightened, but the backlash remained, perhaps the sleeve or the hinge finger itself was worn. In this case, it is necessary to replace worn-out parts or install repair bushings.
What is better to lubricate the hinges in winter: spray or thick lubricant?
In winter, it is better to use thick lithium or Teflon lubricants that do not freeze. Liquid sprays can quickly freeze or leak out, leaving the mechanism dry. The thick lubricant will provide more stable protection in low temperatures.
