Why is My Car Making a Scraping Noise?

Squeaking and grinding noises while driving can be startling and confusing, but the cause of this noise is not always a huge threat to the vehicle. In some cases, squeaky noises are due to normal wear and tear on vehicles, while in other cases they may indicate a bigger problem. This article may help with pinpointing the cause of these strange noises and what to do.

Why is there a grinding noise while driving?

Brake pads

Worn out brake pads cause a squeaking sound due to the exposed metal components rubbing against the disc when the brakes are applied. As the brake pads become worn down, they begin to move closer to the brake discs, and since they don’t fit as well as new ones, they can vibrate and create a high-pitched squeaking sound.

Wheel bearing

Worn-out wheel bearings can cause a squeaking or droning rumbling sound when the bearing’s internal parts start to wear down and allow for excess movement in the bearing, which makes the metal parts rub against each other and create a squeaking sound.

CV joint

Worn-out CV joints will cause a squeaking, clicking or knocking sound due to metal-on-metal contact. This occurs when the constant velocity (CV) joint becomes worn out and there is excessive play in the joint. As the CV joint moves, it will create these sounds as it rubs against the other components in the assembly.

Lack of transmission fluid

The transmission fluid is responsible for lubricating the internal parts of the transmission, such as the gears, bearings, and other moving parts. Without adequate lubrication, these parts will start to wear down and eventually start to make a squeaking sound.

Why is there a squeaking noise while driving with no brakes applied?

Brake pads that are worn out often cause a squeaking noise while driving without brakes applied. Squeaking can be caused by the metal backing plate of the brake pads rubbing on the brake disc when they become worn. An annoying squeaky sound can also be caused due to a stuck brake caliper which is sometimes accompanied by the vehicle pulling to one side.

It’s important to have a professional inspect your brakes as soon as possible if you’re hearing a squeaking noise while driving when no brakes are applied.

Why does my car squeak when I turn?

The most common cause of a squeaking sound when you turn the wheel is a worn out suspension component such as a ball joint, bushing or even lack of power steering fluid. These components help absorb road shock and keep the wheels in line with the steering wheel. As they wear out over time, they can start to squeak when turned.

Another reason you could be experiencing a squeaking sound is due to a loose or worn out power steering belt. Along with the strange sounds, you may also find the steering wheel harder to turn. Either way, it’s important to get the strange sounds inspected and addressed as soon as possible to avoid a possibility of an unexpected breakdown.

If you’re not sure what’s causing unusual sounds in the car, it’s best to get a professional mechanic to get it diagnosed. Get a diagnostic inspection here.
