Why do cables squeak?
Another nuisance is when creaks and clicks begin to appear when the clutch with mechanical drives is disengaged in the area of the cable.
It’s more difficult to figure out here, because the cable can creak both in the cabin and under the hood. But in such cases it is better to coat the cable completely, especially since it will not take much time. To make it more convenient, the cable needs to be disconnected from the clutch fork and lubricated from under the hood. They do this in different ways, but if the cable is not yet old, then there is no point in removing it completely. You can lubricate it with a syringe and motor oil, methodically pushing the oil under the cable casing. Working areas, those places where the cable comes out of the casing, are lubricated with waterproof grease. Litol 24, for example. Not only the cable in the casing can creak, but also the compensating mechanism. In some cars it is installed under the hood, near the clutch, and in some on the other side, near the pedal, like on the Lada Granta. While the cable is new, it will squeak and click. This is inevitable, but it still needs to be lubricated. It is better to lubricate the compensation mechanism when installing the cable. But if the moment is missed, then you will have to practice acrobatics in the salon. Using the same syringe, you need to get to the compensation mechanism and spray a couple of drops on it. The squeaks should disappear. Magic aerosols are best saved for other occasions.
Individuality of the Lada Priora clutch
Any motorist who is interested in how to adjust the clutch on a Priora should know about the presence of the drive cable auto-adjustment function. In other words, VAZ designers took care of the owner and freed him from the need to constantly adjust the clutch drive mechanism during use. The same ratchet-type system is installed on Kalina , but both there and on Priora it is impossible to do without repeated adjustments. This factor has been confirmed by practice and pages of forum discussions.
How to eliminate a squeaking clutch pedal on a Renault Logan car without visiting a service center?
Experienced motorists can not only replace the Logan front wheel bearing themselves, but also determine by ear the location of extraneous sounds from the clutch mechanism. This allows them to quickly eliminate the source of acoustic discomfort. But it happens that noise appears during movement, when it is not possible to accurately determine the cause. In this case, you have to go through the following points:
- Lubricate the cable.
- Lubricate the gear segment of the pedal assembly.
- Clean and apply new grease to the fork bearing assembly.
- Replace the pedal bracket bushings.
- Replace the cable.
- Replace the release bearing.
Since cable wear is one of the most pressing problems, it makes sense to start the fight against extraneous noise with it. There were cases when the cable began to move along with the braid, and when it jammed, a cracking sound was produced.
Lubricate the cable
There is a certain type of driver who thinks there is no need to worry about it once again - it’s easier to install a new one, and thus get rid of the squeaking clutch pedal on a Renault Logan car forever. Perhaps one can agree with this opinion, but the new cable should still be lubricated - this way it will work for a long time and reliably.
Another type of car owner claims that it is absolutely forbidden to lubricate any cables, they say, this will doom him to a slow death from the abrasive that forms from dirt and sand. Let me disagree with this, because practice shows that a lubricated cable works flawlessly in any conditions.
What to lubricate with? Some use graphite lubricant or Litol, others use WD-40. Aerosol has recently become almost a panacea for all problems associated with friction, corrosion and a number of other phenomena. However, if you listen to experts, all of the above options are unacceptable. Litol, for example, begins to harden already at -15°C, which is unacceptable.
The best option is considered to be CIATIM 221 lubricant, which copes well in lightly loaded friction units at temperatures from -60 to +120°C. Lubricant is applied to the exposed sections of the cable, while reciprocating movements are made.
Lubricating the groove of the gear segment of the pedal
Noise from the pedal assembly inside the cabin can be associated with the clutch pedal toothed cam, which is located under the dashboard. The toothed segment contains a groove through which the control cable passes.
To eliminate the problem of extraneous noise, it is enough to lubricate the inner plane of the groove with Litol. Before starting the operation, you need to pull the cable towards you and remove it from the special pedal holder.
Lubricate the fork support
If the clutch pedal on a Renault Logan continues to creak, you need to inspect one more unit - the fork support. If necessary, it must be cleaned and new grease applied. A seemingly simple operation requires a rather impressive set of tools:
- Silicone lubricant in aerosol packaging.
- Cleaner for brake discs and clutch in an aerosol can.
- Round brush with a long handle for removing heavy dirt.
- NGLI grade grease, e.g. Mobilgrease XHP 222, Chevron NLGI 2. Greases are dark blue in color.
- Disposable plastic syringe 10 ml. The cap must be cut at an angle; it is with its help that lubrication is performed.
Quite often, the cause of squeaking from the clutch is the fork support, the reason is dirt and all its varieties. The procedure helps many people, so do not neglect it. There are no particular difficulties with implementation - this is not a replacement for the Renault front suspension ball joint. The technology is as follows:
- Open the engine compartment hood.
- Pull the cable towards you and remove the tip from the slot of the release fork.
- Remove the rubber boot from the fork base.
- Clean the boot and treat it with silicone grease, then wipe it dry.
- Move the fork all the way to the left and treat the stop with cleaner; remove heavy dirt with a brush.
- Lubricate the stop with grease using a syringe.
- Install the boot and cable in their original place.
Before carrying out work, to ensure comfortable access, you need to remove the power steering fluid reservoir and the air filter hose. The tank should not be completely removed - just hang it on a wire.
If the creaking of the clutch pedal on a Renault Logan car remains after the above operations, then you can try to lubricate the bushings on the pedal assembly inside. It must be admitted that such a measure is unlikely to be effective; according to the manufacturer’s recommendation, worn bushings must be replaced.
Solution
In almost all cases, the problem of a squeaking clutch pedal can be eliminated with the help of lubricant. To do this, you need to lubricate all intensively rubbing parts.
Experts recommend using thick grease (CV joint or something like that) as a lubricant. If the car was designed in such a way that it is impossible to get to the pedal elements or spring, do not despair - there is a way out. Use a slotted screwdriver for this. Apply a little lubricant to its metal part, after which you can reach the necessary places with a screwdriver.
There is also a possibility that the squeak does not come from the pedal, but from the clutch fork. During operation, it serves as a place for dirt and used lubricant to accumulate. Because of this, this unpleasant sound appears.
In order to eliminate squeaking in the clutch fork, it must be washed from dirt. Naturally, it is very difficult to reach it, so this must be done through the engine compartment. To clean, you can use carburetor cleaner - it will do the job perfectly. Once you have removed all the accumulated dirt, apply a coat of thick lubricant to the fork.
Other possible squeaks
In addition to the clutch pedal, the reasons for the appearance of squeaks we have already figured out, the reason may lie elsewhere. For example, if the clutch mechanism uses a cable drive, then it is often the cause of unpleasant sounds. If this is the case, simply changing the lubricant will not help solve the problem. To do this, it is necessary to replace the clutch cable.
If you hear a squeak somewhere from the engine, this indicates a faulty release bearing. To fix this problem, you will most likely need to replace the release bearing.
The clutch pedal may make peculiar noises due to the clutch actuator. This is due to the fact that all the work of the clutch is mechanical friction of the working parts. Naturally, the appearance of noise cannot be avoided. In order to get rid of annoying sounds, you will need to periodically lubricate the rubbing parts. Because you will not be able to control a constant level of lubrication - everything is washed off during operation.
There is a more difficult way out of this situation. Using a skilled turner, turn the bushing between the rubbing parts from a softer metal or polycarbonate. In this case, the occurrence of unpleasant sounds will stop, because the friction of different materials will not create such noise as two materials of the same density and structure create.
Many owners of Lada Granta, Kalina and Priora notice the creaking of the clutch pedal. Moreover, this problem may arise after the first kilometers of driving. We will tell you about the possible causes of this disease, as well as ways to solve it.
First, make sure your car's clutch is adjusted correctly. While holding the clutch cable end in an extended position, measure the size between the fork and the driver, it should be 27 mm. How to adjust the clutch cable is shown in the video:
https://youtube.com/watch?v=vYme_hsn6nM%23t%3D210
About 11% claim that the causes of clutch squeaking were in the clutch cable
Pay attention to the presence of a spring in the tension mechanism; Lada Kalina 2 and Lada Granta may not have it. It is worth noting that this spring is present on the clutch cable of the Lada Priora and the owners of these cars practically do not encounter a squeaking clutch pedal
If there is no spring, then it should be installed. Also, it would be a good idea to lubricate the clutch cable using a thin tube, or, if suitable, install a clutch cable from Lada Priora (catalog number: 21700-1602210).
Even less often (about 4% of owners) they solved the problem of a squeaking clutch pedal by lubricating the tip of the clutch cable. Apply lithol to the contact point between the plastic cable nut (No. 2) and the clutch fork (No. 1).
And about 3% of owners solved the problem with the help of lubricant (graphite) of the gearbox input shaft. To do this, you will have to remove the boot from the clutch fork lever (No. 6), and then lubricate it by inserting a tube from a lubricant can into the hole.
Most often (in 24% of cases), the creaking comes from the plastic pedal bushing, which rubs against the bracket. In this case, you should simply lubricate the rubbing areas with lithol.
In conclusion, I would like to note that it is better to start diagnosing a malfunction by determining the source (direction) of extraneous noise. Then you won't have to do extra work. Let us remind you that knocking noises on Lada cars can also come from the steering rack.
Engaging and disengaging a working clutch occurs silently. If squeaks and noises appear, it’s time for you to have the part diagnosed.
Clutch pedal mechanism
Often squeaks appear as a result of wear and tear on the pedal mounting mechanism itself. The return mechanism may also make noise. These problems occur in both mechanically and hydraulically driven vehicles. The creaking mainly occurs when the pedal is released, when some parts of the mechanism are released from the load. In principle, knowing exactly how the clutch pedal is attached in a particular car, it is not difficult to troubleshoot the problem. Only mechanical connections and the return spring can creak in the pedal assembly when pressed. The problem in most cars is one - how to get to the pedal block. In cars with a large interior, this is a little easier, but try turning around in Kalina or Daewoo Matiz.
The clutch pedal may squeak due to wear on the pedal mounting mechanism.
As a rule, the pedals in all cars are suspended on a bracket and fixed to an axle, and easy pedal travel is ensured by plastic bushings through which the pedal is mounted on the axle. In principle, the bushings are not lubricated, but only replaced when they are severely worn. But they can creak regardless of their service life. To eliminate squeaks, it is best to unharness the spring and remove the entire pedal block. At the same time, you can lubricate the brake pedal. The problem is that this operation is labor-intensive and takes half a day. First, you should try to drip motor oil into the bushings from a syringe. This is much easier to do than lubricating the pedal unit when completely dismantling it.
If the creaking of the bushings does not disappear, then you need to get to the return spring. It can creak on its own or touch the metal bracket, as on the Polo Sedan or Grant. The spring should not be lubricated with engine oil, as this will only lead to a dirty interior. Magic products like WD40 can solve the problem for a couple of days and nothing more. Therefore, in such cases it is necessary to use lubricant for CV joints. That's what it's called. Lubricant is sold in tubes or jars, but in this case it is much more convenient to use a tube. The creaking is removed by 99%.

“Fucking basin. “
Hi all! My name is Misha, for now I’ll tell you the story of how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was breaking, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the 10s.
Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not the latest one, on credit is unreasonable. My salary is 24k per month, so collecting 600-700 thousand is virtually impossible for me. I started finding different methods of making money on the Internet. You can’t imagine how many scams there are out there, what I’ve just tried: sports betting, network marketing, and even the Vulcan casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that you could make money was currency trading on the stock exchange, they call it Forex. But when I started to delve into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, learning trading strategies. I tried it on a demo account, later I opened a real account. To be honest, I didn’t manage to start making money right away, until I figured out all the mechanics of options, I lost about 3,000 rubles, but as it turns out, it was a precious experience. At the moment, I’m earning 5-7 thousand rubles a day. I managed to buy a car after half a year, but as for me this is a good result, well, it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone) ) If you want to change your life like me, then here’s what I advise you to create right now: 1. Register on the website 2. Practice on a Demo account (it’s free). 3. As soon as something works out on the Demo account, top up your REAL ACCOUNT and go to REAL MONEY! I also advise you to download the application to your phone, it’s much more convenient to work from your phone. Download here.
Over the course of several days, pour 5–10 drops of motor oil into the hole formed and close it with a stopper. In this way, the oil will penetrate into the gap between the bushing and the fork shaft, flow down the shaft and lubricate the lower support. The clutch pedal will be soft without repairing the checkpoint (Checkpoint - a point designed to control passage (visit) and access to the territory of any facility)
. Lubrication will also eliminate clutch pedal squeaks. A similar modification is suitable not only for the VAZ 2110, but also for the VAZ 2109, because The boxes of these cars are of the same type.
By the way, if the car is old, then the clutch drive already has wear, distortions and, as a result, difficult movement of the clutch. Repair the checkpoint (Checkpoint - a point designed to control passage (visit) and access to the territory of any facility)
For the sake of such a little thing it’s unlikely to be purposeful. To compensate for losses in the drive, you can install a spring on the fork lever (with a force of 1 kgf). You should not use an excessively hard spring; it will only interfere with full activation.

Squeaks when using the clutch pedal
As mentioned above, the Lada Granta clutch cable drive has a circuit that provides for the presence of a wear compensator (automatic tensioner). Its participation in the work process significantly simplifies the operation of the vehicle, since it eliminates the need to independently adjust the clutch fork gap or adjust the pedal. However, shortcomings in the production assembly (some of which we mentioned above) reduce the functioning of the wear compensator to nothing.
The solution to the problem involves a complex that includes several, not technically complex, measures:
The initial step is to adjust the clutch fork clearance. This process involves two options:
a) With removal of the air filter housing. We dismantle the (cold) air intake pipe, the air supply pipe to the receiver, and the wiring of the (mass) air flow sensor one by one. We disconnect the electrical harnesses attached to the filter housing, release the housing from the grip of the rubber stops, and then remove it.b) Without removing the air filter. This method is less common because it requires quite a lot of effort to perform manipulations in the limited space of the engine compartment.
To set the clutch fork gap to 27 millimeters, we perform the following manipulations. Pull the clutch cable all the way (in the direction of vehicle movement) and by twisting (unscrewing) the plastic “lamb”, set the required gap (L) between it and the fork.
The next stage (after setting the working gap on the fork) of a set of measures to eliminate the causes of extraneous noise during operation of the clutch pedal will be lubrication of the elements of the pedal assembly. As a lubricant, experts recommend using a substance that is extremely popular among car enthusiasts - WD-40. Lubricant is supplied not only to the clutch bushing, but also to the plastic ratchet that compensates for wear. Applying lubricant to the cable sheath won't hurt either.
In addition to the information presented above, let's look at a few more reasons that cause squeaking clutch pedals.
One of these reasons may be the friction of the plastic bushing, which is one of the parts of the pedal mechanism, on the bracket. This happens when the pedal is pressed on the microswitch of the mechanism that automatically tensions the clutch cable.
Advice!

The clutch pedal should be installed at the level of the other two, otherwise there is a chance that the reverse gear simply will not engage.
If all the manipulations to lubricate all rubbing parts and mechanisms did not help you, and the problem remains unresolved, then in such a situation the best option would be to contact a specialized service center for diagnostic analysis.
Because solving problems with the gearbox and clutch in advance can prevent you from unexpected breakdowns and further expensive repairs.
- For lubricants in hard-to-reach areas, it is best to use WD-40 or a silicone lubricant in spray form. Thus, the material will be better distributed on the surface and will reach all places that are difficult to reach manually.
- It is recommended to lubricate the clutch pedal and fork cable fastenings with graphite lubricant, which has a beneficial effect on such mechanisms and holds well on devices subject to constant load.

Another source of squeaking may be an insufficiently lubricated input shaft of the box, in the place where the pressure bearing “runs”. This is where it transfers the force received from the clutch fork to the clutch disc. To eliminate squeaking, use a can of graphite lubricant. Lubrication can be done in two ways:
— placing the vehicle on a pit and dismantling the protection of the power unit;
— dismantling the air filter and the clutch fork lever boot.
How to stop squeaking when pressing the clutch?
Often the cause of a squeak is a cable on which the lubricant has dried. If it is not old, there is no need to completely dismantle it. Just take a syringe and lubricate the cable from the hood and interior.
How to remove squeaking noise when pressing the clutch:
- Push the nozzle of the lubricant bottle deep under the casing and inject the oil. After carrying out the manipulation, do not forget to treat the casing joint with a water-repellent agent to prevent water from entering.
- Usually aerosols help little in such cases, since they do not completely penetrate under the casing. Two drops of oil will save the situation and eliminate the squeak. It is more difficult if the creaking does not occur in the pedal itself, but in the clutch mechanism.
- Typically, this situation is often observed in VAZ cars, where the creaking is caused by the clutch fork and bushing. Lubrication in this area is very difficult due to limited access.

on the priors there is a rubber seal, at least lubricate the tensioning mechanism or not, the output will click one cable from the 10th family
I poured WD 40 where the pedal is, under the boot on the cable where it clings to the fork, and under the fork boot in the box
you need to lubricate the cable... and everything will go away + see the tension
There was also a problem a month after the purchase)) and this is a new machine)) there was a creaking from the mechanism, I spilled a lot of VD)) for six months nothing arose.
Specifically, in the priorotros there is a spring in the mechanism that tensions the mechanism, preventing it from creaking. Maybe someone doesn’t have a spring, then you can see how I fixed it, creaking in the sense

Why does a squeak occur when the clutch is released?
Very often, along with a squeak, other problems associated with the clutch pedal may arise. Basically, the pedal can be hard to move and is pressed jerkily.
Why does a squeak occur when releasing the clutch:
- In this case, it is necessary to urgently undergo diagnostics, since with further operation of the car, the fork or the cable that connects the clutch pedal to the car parts under the hood may break.
- Most often, the squeak appears when the clutch pedal is released, that is, at moments when there is no pressure on it. When all the mechanisms are under pressure, they work more smoothly. As soon as the pressure decreases, a squeak occurs.
- There are several options to solve the problem. Of course, it is best to remove the pedal, disassemble it and lubricate all the components. However, this manipulation takes a lot of time; even experienced car enthusiasts can do the job for half a day.
The essence of the problem
Everyone decides to fight this scourge on their own, using their own resources (using the “scientific” method) or uses the advice of experienced “logan breeders” who have conquered this terrible “melody”. In this article you will learn about where this squeak comes from and how to cure it with your own hands.
We are looking for the cause
In fact, based on the design of the Renault Logan clutch, creaking can come from anything, from the bolt securing the pedal together with the spring, to the clutch basket with the release bearing. Such problems begin to appear from least to greatest after only kilometers of driving.
We are looking for a solution
Replace the clutch cable if it shows signs of mechanical stress and damage.
If the car's mileage is not too high and there are no problems with the clutch, first of all, pay attention to the condition of the transmission pedal cable. Visual damage, tears and corrosion are the determining indicators for its replacement.
This spring needs to be lubricated first.
If the cable is intact, then it is recommended to treat all rubbing surfaces (including the pedal spring) with silicone grease or WD-40. If such manipulations do not solve the problem, then it is necessary to look for it through the engine compartment, removing that same cable and replacing it with a new one. If this does not help, then the clutch assembly will need to be replaced.
PS
Remember that during operation, during operation, it is not the clutch cable itself that fails, but its casing, which wears out much faster. Therefore, when buying new parts, choose the highest quality of all.
In what cases is it recommended to contact a service station?
Unfortunately, not only squeaking occurs, but also serious problems, among which the most unpleasant and difficult to fix is clutch slipping, which is not uncommon for this model. In such a situation, the only way out would be a visit to the service station. On average, a clutch kit will cost 5 thousand rubles, plus 1-2 thousand rubles. – installation fee.
A visit to a service station can be avoided if you properly care for the transmission and follow the recommendations of experts:
- If possible, do not overstress the clutch. Try to move off gently at a low crankshaft speed (watch the tachometer readings). Otherwise, due to natural inertia, slippage with accelerated wear will occur.
- Do not release the pedal too slowly, as if on a truck: do not be afraid - the car will not stall. Modern cars with synchronizer are equipped with systems that do not involve, for example, double squeezing with re-throttle. In general, feel free to take your foot off the pedal. What was useful in Soviet times is now harmful, and light pressure leads to unwanted slippage and a reduction in resource.
- Do not tow other vehicles when driving uphill. This is especially harmful on slippery, uneven roads.
- Do not hold the clutch in the depressed position, but remove your foot from the pedal, placing the lever in neutral. This loads the box, but spares the clutch.
Thus, how long the clutch will last and how often it will be disturbed during operation depends only on you. Remember: any malfunction can be easily fixed in a timely manner. And if you don’t have the appropriate skills, it’s better not to get down to business, but entrust the responsible mission to professionals.
