With the passage of time it is normal for the car to start having noises that it did not have when it was new. Sometimes even new already has the odd cricket. Many of them are not serious and simply annoying, but others, on the other hand, should alert us and make us think about taking it to the workshop.
Car noise that may be a sign of breakdown
Any machine that is running produces noise, it is normal. The problem is when the sound stops being the same as always and we begin to hear something strange or different at a specific moment.
In any case, if you hear any of these sounds that we
describe to you, the best thing is that you visit the workshop to check it out:
- · Squeal on the brakes : Perhaps the most striking noise that people are most concerned about. Luckily, in most cases it is simply due to accumulated dirt in the brake system or a lack of lubrication between the brake pad seat and its caliper support. However, there are two noises that should alert us. The first of them is a high-pitched sound when we brake and when the pedal is released it stops sounding or does it intermittently. This noise usually indicates that the brake pads are at the wear limit and is produced by a small sheet metal that the manufacturer installs on the pad precisely as a wear tip. If the sound is like a screeching sound similar to what we hear in movies when a train brakes and drags the wheels along the track, the problem is that the friction material of the brake pad has been worn and what is rubbing is the metal pad against the disk. If this happens, we must change the pads as soon as possible to avoid damaging the brake discs (which are more expensive than the pads) or, worse still, the hub or the brake caliper itself.
- · High-pitched squeal when accelerating : surely you've heard it on occasion, especially on a city bus a little over the years. When you start driving, a high-pitched sound is heard. This noise usually originates from the belt that moves the auxiliaries (alternator, water pump, air conditioning compressor ...) when it slides on the pulleys. It can be something as simple as changing the belt or giving it a little more tension or warning us that some of the bearings of the pulleys, the tensioner or an auxiliary is somewhat stiff.
- ·
Knocking on the motor : If we hear a knocking on
the motor that it did not do before, it is best to turn off the motor and ask
for a crane to take it to the workshop. It may be a small thing, but in many
cases it is a connecting rod that has loosened and hits the crankshaft. Repair
is expensive, but it is much worse if we keep going and the connecting rod ends
up seizing or getting out of place and breaks the engine block, which will
force us to put in a completely new engine. Visit this link to gain more ideas: whining noise when accelerating
- · Growl in the steering : Currently almost no new car has hydraulic power steering, almost all are electric. However, there are still many cars driving with hydraulic steering and a relatively frequent symptom is that you hear a kind of growl when turning the direction, especially when we do it almost to the stop. This noise is usually due to a low liquid level, which causes air to enter the hydraulic pump and bubbles in the liquid.
- · Clack when maneuvering : if when we turn the steering wheel to one side and move forward we hear a clear "cla-cla-cla" it is most likely that a transmission's CV joint is worn, probably because the rubber bellows that cover it have broken and has lost the grease.
