Cars making squealing noise creates an uncomfortable scenario as it also draws public attention towards the driver. The high pitch noise indicates a vehicle in need of a maintenance check.<\/p>\n\n\n\n

You might leave such a task to the expert technicians, but knowing what\u2019s wrong under the hood will aid you in diagnosing the problem yourself. This helps you decide whether the car is in need of an urgent repair and enables you to prioritise a maintenance check accordingly.<\/p>\n\n\n\n

Squealing Noise When Driving a Car<\/h2>\n\n\n\n

The high pitch squealing noise from a car generally means a worn-out part under the hood. In other cases, it could also be related to vehicle brakes and steering wheels. Let\u2019s look at some common reasons that may contribute to the sharp noise:<\/p>\n\n\n\n

Worn Out Belt<\/h3>\n\n\n\n

A worn-out car belt needs to be repaired on priority basis before it leads to engine damage<\/figcaption><\/figure>\n\n\n\n

The car belt is used to power and operate engine accessories in the vehicle including steering pump, alternator, water pump and air conditioner. There are two common belt names you might have heard of, timing belt and drive belt.<\/p>\n\n\n\n

The timing belt<\/a> connects the crankshaft and camshaft of the engine. The word timing dictates the belt capability to synchronize the movement of engine valves and piston. The drive belt powers engine accessories. It is often referred to as a serpentine belt<\/a> or V-belt based on its design and shape.<\/p>\n\n\n\n

Since these belts are made of rubber, with time they can go brittle. The constant stretching can harden the material and will cause cracks. The worn-out belt will lead to squealing noise when starting or driving a car. Additionally, in case there is an oil leak, the oil on the belt will allow it to slip and create squeaking noise.<\/p>\n\n\n\n

Worn Out Belt Pulleys<\/strong><\/h3>\n\n\n\n

Belt pulleys tend to rapidly spin when the engine is running and are integral to car drive belts. If the belt is not the culprit for the squeaking sound, it might probably be the belt pulleys. A damaged or worn out pulley bearing will usually require a replacement to function quietly.<\/p>\n\n\n\n

Faulty Belt Tensioners<\/strong><\/h3>\n\n\n\n

In the old cars, you could manually adjust the belt tension to compensate for stretching, while keeping the engine running smoothly. In modern cars, belt tensioning is automatic and can wear out over a period of time of constant adjustments.<\/p>\n\n\n\n

If you hear a squealing sound, it could either be an overstretched belt that can no longer be adjusted or a problem with the tensioners themselves. If the belt and pulleys are working fine, you will probably need to replace the tensioners.<\/p>\n\n\n\n

Failing Alternator<\/strong><\/h3>\n\n\n\n

Most modern cars have belt-driven alternators. The purpose of alternator in cars <\/a>is to convert engine power into electricity for various electronic components and recharging of the battery. A failing alternator means its inside bearings have gone old and worn out. This can lead to loud squeaking noise.<\/p>\n\n\n\n

Getting the alternator should become a priority as a completely failed alternator can make your car powerless with a dead battery.<\/p>\n\n\n\n

Problems With Steering System<\/strong><\/h3>\n\n\n\n

Squealing sound from a car during road turns means one thing, the problem lies with the steering system. However, there could be various reasons for the high pitch sound in the steering wheel. Some common reasons include:<\/p>\n\n\n\n
