Whenever a vehicle is being reversed or driven backwards for parking, it makes some noises. Some noises in a car are to be anticipated and are not cause for panic, but other noises indicate a problem with the vehicle. You should not ignore a clunking noise, but rather fix it as soon as possible.

The brakes are the most prevalent cause of this clunking sounds. In addition to this noise, putting the gear stick into reverse may cause the vehicle to tremble and make squealing noises. If this has happened to you, know that you’re not the only one.

Why is the car making clunking noises when reversing?

1. Problems with the brake pad

Clunks when reversing can be caused by worn out brake pads that scrape against the rotor. When an automobile is not properly maintained or the brake pad and caliper surfaces have been subjected to a lot of movement, this is a common occurrence. As a result, the brakes make a lot of noise when they malfunction. You may also hear rattling if the brake anti-rattle chips are damaged.


Lubrication. Applying a disc brake caliper lubricant is the initial step in resolving these noise issues. Anti-clunk chips can be installed if the clunks continue to occur. If you don’t install these chips correctly, the noises will continue even if the brakes are brand new. Be careful.

Check the wear tabs on the brakes and make the necessary repairs.

Because of the worn tabs on the brakes, your car is prone to make clunk noises. Check the wear tabs to ensure that doesn’t happen. The brakes of your car have these tabs on the outside.

In order to confirm that the braking system is working properly, the examination is designed to ensure that when the driver steps on the brake pedals, the vehicle will stop. As soon as these tabs start rubbing against the motor, the sounds begin to come back.

2. Check the car to ascertain if there is any metal stuck in the braking system or wheels.

Clunking Noise When Reversing

Metals rubbing against one another can also produce clunking noises. When your car makes this noise while reversing, it may be an indication that something metallic has become lodged between the brake pads and the rotor. The brakes don’t work properly because of an object in the way.

As soon as this occurs, the brakes are carefully inspected and cleaned to remove any foreign objects and to get the braking system working again.

3. Lubricate the grease shims

Between the brake pads and calipers are where the oil shims live. Breaks are silenced when not in use in order to reduce noise pollution.

4. Problem with constant velocity or transmission problem

A car’s reversing clunk might be caused by issues with the vehicle’s speed or transmission. CV parts in need of a new boot or a replacement for the complete part can be downsized using this technique. Many possible causes exist, but the parking pawl may be to blame if this is a transmission issue. A parking pawl’s primary function is to ensure automatic transmission.


Preventing such noises can be accomplished by coming to a complete stop before parking the car. Even if the car is moving, you should put the transmission in park if you have to hurry since it can damage the parking pawl, which can lead to clunking.

5. Worn out motor mounts and poorly secured engine

To avoid making clunking sounds, make sure the engine and its mounts are securely fastened. Another common reason why you hear a single knock or pop as soon as you shift into reverse and begin driving the vehicle is because of a loose bolt. Also, when braking and shifting gears, you will hear the same sound.

Weakening of the axles that transfer power from the transmission to the wheels is another possible reason of the single knock you hear while driving or pressing the brake pedal in reverse.


These parts should be frequently inspected and corrected if necessary.

6. Problems with the parking pawl

There are pins attached to the output beam to block the wheel from turning, which is what a parking pawl is. Such noises may indicate that your car’s parking pawl needs to be repaired. When reversing, a clunking noise may be the result of a damaged parking pawl.


When the car is parked at an angle, the parking pawl will require help. When parking your car on an uphill, be sure to use the emergency brake.


If your car’s parking pawl, worn out, has a poorly secured engine, or has other brake troubles, clunks can be heard while reversing. Identifying the source of the noises and devising a workable solution are the first steps in finding a solution to these issues.
