What parts do I need for my front crankshaft seal replacement and how much do those parts cost?
You can check your owner’s manual or ask your mechanic for precise parts, but here’s the main thing you need:
- Front crankshaft seal: The front crankshaft seal is the main component needed in the replacement. The crankshaft seal works to prevent oil leaks from the crankshaft. On its own, it costs anywhere from $10 to $60.
- Timing belt or timing chain: Since the front crankshaft seal is located behind the timing belt or chain, it's a good idea to replace the timing belt or chain along with the seal. This preventive measure avoids having to dismantle the timing system again if it fails at a later date. A new timing belt or chain can cost anywhere from $15 to $400.
- Crankshaft pulley/harmonic balancer: The crankshaft pulley or harmonic balancer may need to be removed to access the front crankshaft seal. It is advised to inspect these parts and replace them if there are any signs of wear or damage. On average, a new crankshaft pulley can range from $50 to $300.
- Camshaft seals: Depending on your vehicle's design, you may need to replace the camshaft seals as well, especially if they show signs of leaking or wear. A new camshaft seal costs between $5 and $35.
- Accessory belts: It’s a good idea to inspect your accessory belts during a front crankshaft seal replacement. If they’ve suffered any damage or general wear and tear, it’s more cost-effective to replace them when you’re working on your seal. Replacing accessory belts (such as the serpentine belt) costs approximately $10 to $65.
- Gaskets: Consider inspecting and replacing any of your car’s gaskets that are related to the front crankshaft seal. These can cost you anywhere between $10 and $60.
You can buy front crankshaft seal 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 eBay. Three of our recommended brands for front crankshaft seal parts are Fel-Pro, SKF, and Timken. However, the best parts and brands for your front crankshaft seal replacement will vary depending on your vehicle’s year, make, and model.
Should I buy an OEM or aftermarket front crankshaft seal?
Most mechanics will recommend opting for an OEM crankshaft seal. While they might be pricier, OEM crankshaft seals typically last longer and offer more reliability compared to their cheaper aftermarket alternatives.
Where can I buy a front crankshaft seal replacement?
You can purchase front crankshaft seals at body shops and auto parts shops like AutoZone, NAPA Auto Parts, and Advance Auto Parts. You can also shop for them on Amazon or eBay.
Before getting any replacement parts, consult your vehicle’s owner manual to ensure you’re purchasing the right type for your vehicle.

How will a mechanic replace my front crankshaft seal?
When a mechanic replaces a front crankshaft seal, they will normally follow these steps:
- Raise and support the vehicle on jack stands to access the harmonic balancer, located on the front motor and attached to the crankshaft
- Remove the accessory belts to get to the necessary apparatus
- Remove the faulty crankshaft seal by prying it loose using a seal puller
- Install the new oil seal, lubricate the seal using fresh motor oil, and tap the seal back into place with a hammer
What happens if I don’t replace a bad front crankshaft seal?
This is not a replacement service you want to put off. Allowing your front crankshaft seal to continue to leak can cause detrimental damage to your vehicle.
Not only will your engine suffer from running without oil, but the broken seal will also cause oil and other debris to spread through your engine bay and the undercarriage of your car. This is difficult to clean and can be a fire hazard.
What is a front crankshaft seal?
Front crankshaft seals are one of the most important parts of your car. Located in front of the engine and behind the main pulley that drives the serpentine and timing belts, they keep your car moving forward and protect the undercarriage from debris and other harmful contaminants.
Crankshaft seals are typically made of extremely durable materials, such as rubber or silicone. They are designed to handle high temperatures and caustic chemicals in your engine oil daily, but they are subject to regular wear and tear.
When should I replace the front crankshaft seal on my car?
Here are some common symptoms indicating the need for a front crankshaft seal replacement
- Oil leaking from the front crankshaft pulley of your car
- Oil dripping from the bottom of the clutch housing
- Low oil level
- Oil puddles underneath your car
- Clutch slipping due to oil spray
- Engine noises when you accelerate or turn, or a hissing sound from the engine bay
- Smoke from under the hood
- Diminished engine performance and fuel economy
How often do you need to replace a front crankshaft seal?
While there’s no specific timeline when it comes to the lifespan of your front crankshaft seal, it will need to be immediately replaced if you notice an oil leak. On average, crankshaft seals last around 100-150k miles.
Is replacing a front crankshaft seal yourself easy?
Unless you’re very experienced in DIY mechanical projects and auto repair, replacing a front crankshaft seal is challenging. For the average driver, it’s best to visit an auto shop and let a certified technician perform the job.
FAQs
What causes a front crankshaft to leak?
Several problems can make a crankshaft seal leak, but here are a few common reasons:
- Wear and tear of the crankshaft: If the crankshaft hasn’t been replaced in a long time, this can make the seal loose, which can lead to leakage.
- Damaged gaskets: When the gaskets are overexposed to high temperatures for some time, the rubber can degrade.
- Cracked shell: The crankshaft seal is encased in a metal shell. If this shell develops cracks, it can lead to the mixing of air and oil, causing leaks.
- Foreign objects: When external elements like dust, grit, or dirt find their way into the engine, they can become trapped between the seal and crankcase wall, causing friction and eventual leakage.
Is a leaking crank seal bad?
Yes, a leaking crank seal is bad. Ignoring a leaking crank seal can lead to engine damage and the potential for total engine failure.
Is replacing a crankshaft seal a big job?
Replacing a crankshaft seal can be a challenging task. It may require working on the engine or dealing with another intricate component of the car.
