Creaky doors can irritate even the calmest driver. This annoying sound not only spoils the ownership experience by car, but also signals the beginning of destructive processes in the opening mechanisms. Ignoring the problem leads to wear of the bushings and the appearance of backlash, the elimination of which will cost more than timely prevention.
One of the most effective solutions in the auto chemicals market is the products of the German brand Würth. The line of lubricants of this company has established itself as a standard of reliability under operating conditions. Correctly selected hinge lubricant ensures the durability of the unit and returns silent operation.
In this article we will look in detail at what compositions Würth are best suited for door awning maintenance. You'll learn the differences between spray lubricants and grease lubricants, and receive step-by-step instructions on how to apply them.
Why do car door hinges squeak?
The main reason for the appearance of extraneous sounds lies in the washout of the factory lubricant. Under the influence of precipitation, high-pressure washers and temperature changes, the protective layer becomes thinner. Metal begins to rub against metal, which generates a characteristic squeal.
In addition, road dust and abrasive particles get into the gaps between the pin and the bushing. This mixture works like sandpaper, accelerating the wear of rubbing surfaces. Corrosion also plays an important role, especially if the body already has paint chips in the hinge area.
There are several types of squeaks that help diagnose the problem:
- 🔊 A sharp metallic squeal when opening - a complete lack of lubrication.
- 🔊 A dull crunch when the door moves - sand or dirt gets in.
- 🔊 An intermittent squeak is the beginning of the corrosion process inside the bushing.
If you do not intervene in the process in time, the geometry of the loops may be disrupted. This will cause the door to warp and not close tightly. In this case, you will no longer need just lubrication, but complex body repairs with overcooking or replacing elements.
Overview of Würth hinge lubricants
Product range Würth is extensive, and not all compounds are suitable for door hinges. It is important to choose products that have high adhesion and resistance to being washed off with water. Universal penetrating liquids will not help here, as they are intended for something else.
The most popular solution is lithium grease in an aerosol can. It penetrates deeply into the gaps, displaces moisture and creates a dense protective film. After the solvent evaporates, a thick layer remains that does not drain and lasts for years.
It is also worth paying attention to synthetic lubricants with molybdenum disulfide. They have extreme anti-seize properties. For heavily loaded components, such as the hinges of heavy SUVs, this may be the optimal choice.
⚠️ Attention: Never use graphite lubricants on white or light-colored cars in the hinge area. Graphite can leave permanent black marks on the paintwork when the door rubs against the body.
Specialized spray Multi-Spray plus often confused with lubricant. It cleans well and protects against rust, but its lubricating abilities are limited in time. For long-term effect, it is better to use specialized products from the series HHS 2000 or lithium sprays.
Preparing to process door awnings
Before applying a new composition, it is necessary to carefully prepare the surface. Old, dried grease and adhered dirt will reduce the effectiveness of the new material to zero. The preparation process requires care so as not to damage the paintwork.
It is recommended to open the door as wide as possible first. If the design allows you to fix it in an intermediate position, use it. This will provide access to all sides of the hinge axles.
Special brake cleaners or all-purpose degreasers are ideal for cleaning. Würth. They quickly dissolve old fat deposits and are easily washed off. After treatment with the solvent, the surface must be wiped dry with a rag.
☑️ Checklist for preparing loops
It is important to protect adjacent body elements and rubber seals from aggressive chemicals. Rubber can crack from contact with solvents, and plastic can be left with dull spots. Use masking tape to cover the areas around the hinges.
Lubrication technology
The application process depends on the selected packaging format. If you are using a spray with a tube, direct the stream directly into the gap between the finger and the hinge body. Using short presses, fill the inner cavity.
After application, you need to open and close the door several times. This action will help distribute the composition over the entire friction surface and squeeze out any remaining moisture or dirt out. Any excess that appears should be immediately removed with a napkin.
For greases in tubes or syringes, the technology is different. The composition is applied in a thin layer to the visible parts of the axle. Then the door is actively worked to “drive” the lubricant inside. Excess is also removed.
The nuances of working with HHS 2000
HHS 2000 spray initially has a liquid consistency, which allows it to flow into the most microscopic gaps. After a few hours, the solvent evaporates and the lubricant becomes a thick, sticky mass that is not washed out with water.
Pay special attention to the top surface of the hinge. This is where water most often accumulates and corrosion begins. Cover this area generously with a protective compound, creating a kind of “cap” of lubricant.
Comparison of characteristics of Würth lubricants
To choose the optimal product, it is worth comparing the main parameters of popular formulations. Differences in the chemical base determine the service life and operating conditions.
| Parameter | Lithium spray | HHS 2000 | Synthetic lubricant |
|---|---|---|---|
| Base | Lithium complex | Mineral oil | Synthetics |
| Temperature | up to +120°C | up to +160°C | up to +180°C |
| Water resistance | High | Very high | Maximum |
| Color after drying | Transparent/Yellow | Transparent | Grey/Black |
As can be seen from the table, HHS 2000 has excellent adhesion but takes time to cure. Lithium sprays work immediately, but may require more frequent refills under extreme use.
Synthetic compounds are universal, but their price is usually higher. For regular non-rally passenger cars, a good quality lithium spray or HHS is sufficient.
Apply lubricant in a warm garage. In cold weather, the viscosity of materials increases, and they penetrate worse into the working gaps of the hinges, remaining on the surface.
Typical maintenance errors
Often, car enthusiasts, wanting to save money or simplify a task, make mistakes that lead to the opposite effect. Instead of silence they get accelerated wear. The most common mistake is using WD-40 or its analogues as the main lubricant.
These liquids are solvents with light oily additives. They perfectly wash away old grease and dirt, but by themselves do not create a long-lasting protective layer. After a couple of days, the door will squeak again, and more strongly, since the factory lubricant will be completely washed out.
⚠️ Attention: Do not apply fresh lubricant over old lubricant without first cleaning the hinges. The new layer will not be able to penetrate the rubbing surfaces and will work in vain, only collecting dust.
Another mistake is over-application. Thick streaks of grease hanging from the hinges actively collect road dust. The resulting abrasive paste will accelerate the destruction of the bushings. The lubricant should cover the metal in a thin, even layer.
Don’t forget about the mating parts of the hinges on the body. Often only the moving part on the door is lubricated, forgetting about the stationary part on the counter. Friction occurs in pairs, so both elements need to be processed.
Maintenance Frequency and Prevention
The regularity of treatment depends on the operating conditions of the vehicle. If you live in a region with a harsh climate, where roads are actively sprinkled with reagents, or you often wash your car with a Karcher, the service interval is reduced.
Preventive inspection and lubrication of hinges once a year is considered optimal. It is best to carry out this procedure in late autumn, before the start of the winter season, or in early spring, after the end of the reagent period.
When the first signs of squeaking appear, do not delay servicing. At the initial stage, it is enough to simply blow out and lubricate the hinges. If the metal has already begun to “gnaw” the metal, repair or replacement of the bushings will be required.
Regular lubrication of hinges once a year increases their service life by 3-4 times and prevents door distortion, maintaining the tightness of the interior.
Monitor the condition of the door opening limiters. They also require lubrication, but it is better to use grease for them, which will not flow down, staining the sills and clothes of passengers.
FAQ: Frequently asked questions
Can hinges be lubricated with motor oil?
The use of motor oil is not recommended. It is too liquid, quickly flows out of the friction zone and does not have the necessary anti-scuff properties. In addition, oil strongly attracts dust, turning the hinges into an abrasive mechanism.
How to remove old dried grease if there are no special tools?
You can use Galosh gasoline or white spirit. Apply the liquid liberally to a rag and thoroughly wipe the hinges, using a soft brush for hard-to-reach areas. The main thing is to completely degrease the surface before applying new lubricant.
Will lubricant help if the door is already sagging?
Lubrication will eliminate squeaking and make movement easier, but will not correct geometric sagging. If the door touches the threshold or does not close well due to play in the hinges, mechanical adjustment or replacement of worn bushings and pins will be required.
Is Würth lubricant safe for rubber seals?
Most specialty lubricants Würth inert to rubber and plastic. However, if you use aggressive solvents or petroleum distillate-based lubricants in large quantities, it is better to protect the rubber parts with masking tape or use silicone compounds.
