Chevy Silverado Clunking Noise When Accelerating – What Is The Reason?

Any noise a car makes when accelerating is a warning of serious problems you need to know to fix. The noise can appear at a low volume, then gradually increase and even form a loud squeal every time you accelerate the car.

There are many causes of Chevy Silverado clunking noise when accelerating. Let’s explore the common causes of noise when the Chevy Silverado accelerates.

Top 5 Reasons Why Chevy Silverado Clunking Noise When Accelerating

Let’s analyze in detail the causes that can lead to the Chevy Silverado making annoying noises when accelerating on the road.

1. Problems With The Engine

Engines have many moving parts and joints between connecting rods or bearings. Chevy Silverado making a loud noise when accelerating can indicate an engine problem, and you need to fix it as soon as possible.

If this situation occurs for a long time, it will lead to engine failure and replacement costs.

Some of the parts you should prioritize to check are:

  • Worn valves can make a rattling noise and may be more noticeable when the vehicle is moving faster.
  • Bearings and rotating crankshafts can also make a lot of noise when you accelerate your car if it shows signs of failure. They will make sounds like a tick or even a hiss when they have serious problems.
  • Pistons are also a leading cause of noise during acceleration. They will make a rattle if they are worn and you will hear it all the time and more clearly when accelerating.

For engine safety, be sure to check these key areas first, don’t continue driving, and address the problem promptly so it doesn’t cause bigger problems.

2. The Transmission Belt Is Broken

Chevy Silverado engines come with a variety of belt-driven attachments. Each of these accessories uses a pulley to drive, along with one or more different sets of bearings in the system.

The engine of Chevy Silverado has some mechanical parts attached to it to perform essential functions such as providing power (generator), cooling the engine (water pump), helping to drive the car easier (power steering oil pump), and keep you comfortable (air conditioner compressor). Without the drive belts, none of these parts would work.

The purpose of the drive belt is to transmit power between different engine components. They work by friction between the belt and the pulley, which is why loose belts can cause different parts to work poorly or not at all.

If the drive belt is damaged, other components may not work properly. Chevy Silverado can be hard to start or won’t start at all, and belts can “squeak” as you accelerate.

A loud squeal or squeal when accelerating could be a problem with your engine belt. It could mean that the belt is loose or worn. Or it could mean that one of the belt pulleys is starting to fail.

This loud noise will become more pronounced and louder due to causes such as cracked, worn, or broken belts or poor belt tension.

3. Lack Of Power Steering Fluid

When there’s a lack of power steering fluid, one of the first telltale signs is noise when you’re driving or more obvious when accelerating.

In addition, under the steering wheel can also make a rattling sound. The cause may be a lack of oil or the power steering pump is not working properly.

One of the other common signs is a slow steering wheel. The ruler moves slowly due to reduced pressure and low oil flow, or oil leaks into the adjacent chamber. If the steering wheel ring is not sealed, the oil will overflow and cause delayed return.

In this case, the steering rods are not lubricated regularly, causing them to wear and slow down. Or because the tires are worn out by incorrect steering alignment, they also create annoying noises.

Besides, loud noise when accelerating could indicate a problem with your exhaust system. There could be a leaking oil somewhere and the rumbling is the sound of your system working harder to deal with excess exhaust fumes.

To deal with this noise, you should regularly check the amount of oil in the engine or power steering system to make sure they are lubricated regularly and there are no strong bumps that lead to creaking noises.

4. Worn Wheel Bearings

The job of wheel bearings is to ensure that the wheel will rotate freely while on the road. Wheel bearings tend to wear out over time if not serviced periodically.

In most cases, a badly worn wheel bearing will make a loud noise when the driver is moving on the road. This noise usually changes as the vehicle accelerates. At high speeds, this sound is often reminiscent of a “humming” or a “hissing”.

You can check for faulty wheel bearings when cornering. If the sound changes in tone or stops completely while turning, the wheel bearings could be a suspicious cause.

5. Gearbox Error

The gearbox plays an important role in distributing engine power to the transmission shafts of the car. However, gearboxes are also often damaged over time.

In some cases, transmission failure can be detected. The noise can be difficult to identify because it resonates with the sound under the car.

The sound coming from the gearbox can be caused by a lack of oil, leaking oil, or a damaged transmission oil pump. Worn bearings also often cause noise under the car.


If the Chevy Silverado makes noise when accelerating, you can check out some of the causes we mentioned above. In addition, we also list some more common sounds you may encounter frequently while on the go. Identify the cause and fix it early to minimize repair costs.

  • Grinding: There could be a problem with your clutch or with your car’s entire transmission or engine wear.
  • Rattle: Check for any loose or rattling parts due to lack of lubricant, joints, bearings, etc.
  • Tick: An unusual ticking sound means your car is running low on oil.
  • A creaking sound: This could be a sign of a problem with the brake system. Your wheel bearings are wearing out or problem with the brake pads or discs.
  • Rumble: Exhaust system problem due to fuel leak or exhaust pipe cracked, broken.
