Wipers are the thing in the car that drivers use almost every day. Many are faced with the problem of squeaking. And if short-term trips allow you to survive this problem, then at long distances this annoying sound can be pretty annoying. How to solve this problem? Why do wipers squeak on glass? Look for answers to these questions in our today's article.
The most common reason why wipers creak is the quality of the brush itself. Imagine the situation - heavy rain caught you on the road, and the old wipers are unable to clean the glass. You go to the nearest supermarket and buy a set of new ones.
However, after installation, you hear a characteristic creak. But where did he come from, because the brushes are brand new? The creak of new products indicates that the rubber band is not able to cope with its task and "smear" on the glass. However, the manufacturer is not always to blame. There are frequent situations whenthe driver simply forgets to snap the fastening mechanism to the end. As a result, the brush "walks" on the glass, making a heart-rending sound.
Natural wear and tear
How often should wipers be changed? There is no single answer to this question. Manufacturers themselves recommend changing these elements at least once every 2 years. During this time, the rubber element of the brush dries out and becomes less elastic. Wipers are also distinguished by season. There are winter and summer options. Many use one type all year round. This is not entirely correct. After all, the manufacturer calculates the strength and properties of the wiper according to the temperature regime in which it is operated. If you have not changed them for more than two years, and your wipers creak on glass, the reason is natural wear and tear. You should replace them with new ones.
There are two types of wipers:
Most often wipers of the first type creak. Why is this happening? The brush is fixed in a metal base. If it is deformed, the position of the gum also changes relative to the surface. Also, the brush connections can rust or sour. Especially often this happens in winter, when the frame literally envelops the ice crust. The driver has to literally tear the brush off the surface so that it can work again. Frameless analogues are devoid of this drawback. Therefore, if you buy new ones, then only frameless.
For what other reasons do wipers creak? The sound also occurs due to the presence of dirt underrubber band. Moreover, this dust accumulates on the upper side of the brush. Turning on the wiper, the car owner does not even suspect that the glass will soon be covered with micro-scratches, and the rubber will fail due to the abrasive action of road dust.
Even after a short parking, a layer of dirt accumulates under the wipers. Therefore, to protect the glass from minor scratches and the rubber from damage, periodically clean this area with a dry soft cloth.
Another reason is poor-quality fastening. The janitor should not play. If so, you need to pick up a new mount, or use pliers to press the metal part of the wiper (where the plastic clip is installed). Deformation of the "bow" itself is also unacceptable. The element must rest against the glass at a right angle.
Wipers creak: what to do? Ways to solve the problem
If the windshield wiper suddenly starts to make a characteristic sound, you must first thoroughly wash the glass. It is better to do this with car shampoo. Apply some of the foam to the rubber brush itself. Make sure all contaminants have been removed. This simple procedure eliminates squeaky wipers in 50% of cases.
The next operation is to check the fasteners of the brush. As we said earlier, it should be fastened without backlash. If so, change the plastic latch, or press the edges of the wiper with pliers.
Checking the wiper mechanism
If the shackle adjoins the stele crookedly, the wipers will creak in any case. And no matter how muchyou bought them and what type they are. The elastic will always be directed in the opposite direction. You can fix this by replacing the bow or bending its part to a different angle. As a result, the brush should be strictly perpendicular to the glass. Only in this case, the gum will not crawl on the surface, making a meticulous sound.
Not a superfluous operation would be to check the spring that presses the shackle against the glass. If the surface is cleaned with gaps, while the wipers creak, replace this item.
The spring is changed on the previously removed shackle. It is quite easy to dismantle it - for this you need an open-end wrench for 13. The main thing is to remember its position relative to the turning sleeve. Replacing the spring, install everything in place. Do not overtighten the nut. If the wiper in the off position is not in its place, it does not matter - you can always adjust it again. To do this, unscrew the nut and change the position of the metal bow. The procedure does not take long.
Manufacturers - which is better to choose?
If the problem persists, try replacing the brushes after measuring their length. Please note that it may be different on the left and right wiper. As for manufacturers, the French brand Valeo makes the highest quality products. There are quite a lot of Bosch wipers on the market. However, reviews about them are very mixed. The fact is that there are a lot of fakes on the market. Reallyoriginal brushes will cost at least 700 rubles per set. Among other manufacturers, we note Champion (USA) and Hallo (Austria).
It is better not to save on the quality of wipers, because they will not last long. It is not uncommon for motorists to creak on glass on the second day. What to do? Only replacement will help. By the way, when choosing, it is important to pay attention not only to the price and brand, but also to the presence of adapters. After all, each car has its own type of fasteners. The most popular of them are the "hook" or "claw". On Peugeot and Mercedes cars, the Side pin clamp or “side pin” is used. On Volvo and some Citroen models - Push button. On Renault cars, side mounting or Side mounting is used. When choosing the right brush, be sure to check this point. After all, it is impossible to install the part without an adapter.
So, we found out the reasons why the wipers creak. In most situations, the fault is natural wear, or the poor quality of the rubber bands themselves. Alas, no one is immune from fakes. But you can distinguish a really high-quality product. First of all, this is the price. However, if wipers creak for 2 or more thousand rubles, the cause is a deformed bow. Check at what angle the brush is relative to the glass. We hope these simple tips will help you solve this problem.
