“Dangerous sounds in a car include the following:
1. Knocking in the internal combustion engine when the engine is cold and hot, caused by wear on the crankshaft and piston group. If the knocking sound is also accompanied by a flashing low oil pressure indicator (red light), the car should be turned off and a tow truck should be called.
2. Transmission howling noise, increasing with speed. Sound coming from the front or rear axle, gearbox (automatic transmission).
3. Creaking and squeaking noises from the brake mechanisms, indicating total wear of the brake pads.
4. Clicking noises were heard when driving on the wheels, associated with the destruction of the CV joint.
5. Loud knocking sound from the suspension when hitting a small obstacle. This sound has many causes, but most often it is due to wear on the ball joints, struts and stabilizer bushings.
If knocks appear suddenly, then you should inspect the car yourself for foreign objects that have entered the wheels or engine compartment. Then slowly drive to the service station for a professional inspection and diagnosis. If the sounds scare you and intensify when you accelerate, maneuver, or increase engine speed, then it is better to call a tow truck.
If a creeping sound appears day after day and disappears “when it is cold or hot”, a high-quality diagnosis at a service station is recommended.
To avoid the appearance of dangerous sounds, it is advisable to inspect the exterior of the car before driving, looking for strange noises, the condition of the tires and the presence of oil puddles. A very important point is to carry out scheduled maintenance at a service station and follow the mechanic’s recommendations,” said the specialist.
