How did we estimate these prices?

Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

What parts do I need for my crankshaft harmonic balancer replacement and how much do those parts cost?

Your owner’s manual should outline the parts needed for a crankshaft harmonic balancer, or you can ask a professional mechanic for your vehicle’s specifications. In general, you’ll need the following parts for a crankshaft harmonic balancer replacement:
  1. Crankshaft harmonic balancer: The crankshaft harmonic balancer or harmonic damper—AKA the main component in the replacement process— is a pulley device, usually located near the crankshaft towards the front of the engine. The harmonic balancer is responsible for absorbing vibrations to maintain engine balance. The typical cost of a crankshaft harmonic balancer is $50 to $200.
  2. Crankshaft bolt: The crankshaft harmonic balancer is attached to the front of the crankshaft using a bolt. This bolt is usually replaced during the balancer replacement, and the exact bolt will depend on your vehicle’s specs. Usually, a crankshaft bolt replacement costs $5 to $50.
  3. Crankshaft key: The crankshaft key—or woodruff key—is a small metal piece that helps to correctly align the harmonic balancer. If the key is damaged or worn, it will need to be replaced with the harmonic balancer. Crankshaft keys typically cost $10 to $20.
  4. Crankshaft seal: The crankshaft seal prevents oil leaks from the engine. This part isn’t typically replaced during a crankshaft harmonic balancer replacement, but it should be inspected for wear and tear. Crankshaft seals cost $5 to $50. 
You can buy crankshaft harmonic balancer parts for your car from auto parts stores like AutoZone, NAPA Auto Parts, and Advance Auto Parts, as well as online retailers such as Amazon and Summit Racing. Three brands we recommend for crankshaft harmonic balancer parts are Dorman, ACDelco, and Dayco. With this said, the right parts and brands for your vehicle’s crankshaft harmonic balancer replacement will vary based on its year, make, and model.
Your crankshaft harmonic balancer is an integral part of your engine, so it’s important to get the best replacement part if yours goes bad. 
OEM parts are generally recommended as they’re reliable and long-lasting, made of quality materials, and precisely designed for their designated vehicles. On the other hand, aftermarket harmonic balancers can be cheaper and usually come in a variety of options. 
Both OEM parts and aftermarket parts offer warranties depending on the provider, so you’ll need to make a decision based on the quality value and pricing.
Key Takeaway: Stick to OEM parts if you want a longer lifespan and higher reliability, or opt for aftermarket parts if you need to cut costs.
You can purchase parts for your crankshaft harmonic balancer replacement from auto parts shops like NAPA Auto Parts, AutoZone and Advance Auto parts, or online retailers like Amazon and Summit Racing, or you can go directly to the dealership for OEM parts. You may also find replacement parts at local independent auto shops.

How will a mechanic replace my crankshaft harmonic balancer?

If you notice engine vibrations, misalignment with your engine’s timing marks, or strange engine noises, you may be dealing with a bad crankshaft harmonic balancer. Your mechanic will follow these steps to correctly replace your crankshaft harmonic balancer:
  1. Preparation: Your mechanic will collect the appropriate tools to complete the replacement, including a screwdriver set, a harmonic balancer puller, a socket set, a breaker bar, a torque wrench, and any other vehicle-specific tools. 
  2. Disconnect the battery: For safety purposes, your mechanic will disconnect the vehicle's battery to ensure no electrical power moves through the vehicle during the replacement process. 
  3. Access the balancer: Your drive belts, pulleys, and your engine’s cover will be removed so your mechanic has access to the vehicle’s harmonic balancer.
  4. Remove the balancer: Your mechanic will loosen and remove the crankshaft bolt, which secures the balancer to the crankshaft. Next, they’ll use a harmonic balancer puller tool to remove the balancer from the crankshaft.
  5. Installation: Before installing the new harmonic balancer, your mechanic will clean the crankshaft snout and apply a thin layer of engine oil to help with the installation. Then, the mechanic will align the new balancer with the crankshaft and then slide it into place. If your vehicle also requires a new crankshaft bolt, key, or seal, those will also be applied at this time.
  6. Torque the crankshaft bolt: Your mechanic will reinstall the old crankshaft bolt or install a new bolt. Based on the manufacturer’s instructions, the bolt will be secured with the appropriate torquing specifications.
  7. Reassemble and Test: Lastly, any components that were removed to install the new balancer will be reinstalled. This includes the drive belts, pulleys, and the engine covers. Your battery will also be reconnected at this time, and your mechanic will start your engine to test for vibrations and noises.

What happens if I don’t replace my crankshaft harmonic balancer?

If you ignore a faulty or worn crankshaft harmonic balancer, any of the following potential issues could arise:
  • Engine imbalance
  • Harsh vibrations
  • Crankshaft damage
  • Drive belt issues (ex. Misalignment, excessive movement)
  • Pulley issues
  • Slippage
  • Decreased steering power
  • Timing belt misalignment 
  • Engine seal leaks

What is a crankshaft harmonic balancer?

The crankshaft harmonic balancer—also known as a vibration damper—is a vital engine component designed to reduce harmonic vibrations and prevent damage. 
Picture this: The explosions of fuel and air that power your car’s internal combustion engine create vibrations and torsional force on the crankshaft. Those vibrations can cause damage to internal components and throw off the engine timing. For these reasons, a crankshaft harmonic balancer is necessary.
The harmonic balancer attaches to the front of the crankshaft and is composed of a metal hub, a rubber damper, and a balance ring. 
It connects to the crankshaft via the metal hub, while the rubber damper absorbs shocks and vibrations. The balance ring usually functions as the crankshaft pulley, powering engine accessories like the water pump, alternator, and AC compressor.

When should I replace the crankshaft harmonic balancer on my car?

The most common signs of a bad crankshaft harmonic include:
  • Visible damage: You may notice visible cracks or damage to balance when you inspect the part. If your harmonic balancer is loose, cracked, or separated, it will need to be replaced.
  • Excessive vibrations or weird noises: Your crankshaft harmonic balancer manages your engine’s vibrations, so if you feel harsh vibrations or hear strange noises coming from the engine bay of your vehicle, it may be due to a failing harmonic balancer. If left unchecked, these vibrations can affect other integral parts of your car.
  • Misalignment or pulley issues: A misaligned balancer, belt slippage, or pulley issues may be the result of a faulty crankshaft harmonic balancer. If these issues are not resolved, they can affect your vehicle’s overall performance.
  • Check engine light: Your check engine light will turn on if there is an issue with your crankshaft, including damage to your crankshaft harmonic balancer. Your mechanic can use an OBD-II scanner to check for trouble codes associated with the harmonic balancer.

How often should a crankshaft harmonic balancer be replaced?

Manufacturers do not typically outline specific lifespans or replacement intervals for crankshaft harmonic balancers. With this said, most crankshaft harmonic balancers last 50,000 miles or approximately 10 years.

Can I replace my crankshaft harmonic balancer myself?

If you’re a DIY car repair expert with the tools and knowledge to back the replacement, you may be able to replace your crankshaft harmonic balancer on your own. 
However, a crankshaft harmonic balancer replacement requires a fair understanding of your engine’s complex components, and you’ll also need special tools. If you’re a DIY car repair beginner, opt for a trusted mechanic to ensure your crankshaft harmonic balancer is replaced correctly
