What parts do I need for my differential output seal replacement and how much do those parts cost?
The differential output seal is a single part, so when it becomes worn and no longer functional, it’s generally the only part that needs to be replaced. The average cost for a new differential output seal is between $11.71 and $14.31, but you may pay more or less based on your vehicle.
In addition to the differential output seal, some basic tools and equipment are also required to do the replacement:
- Brake cleaner
- Clean rags or towels
- Drip pan
- Limited slip additive (if you have a limited slip differential)
- Seal removal tool and installation tool
- Screwdrivers
- Socket set and ratchet
- Replacement rear-end oil
- Plastic gasket scraper
- Torque wrench
You can purchase a differential output seal 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 RockAuto. Three of our top recommended brands for differential output seals are SKF, Timken, and National Seal. However, the best part and brand for your differential output seal replacement will vary based on your vehicle’s year, make, and model.
Should I buy an OEM or aftermarket differential output seal?
When it comes time to replace the differential output seal, you will likely be okay purchasing an aftermarket part, assuming it’s the correct dimensions for your vehicle. Although aftermarket parts are typically cheaper than OEM parts, they may not be manufactured to OEM specifications, so the fit won’t be correct. However, if you can find an aftermarket output seal explicitly designed for your vehicle make and model, you may be able to save money without compromising quality.
Where can I buy a differential output seal?
Differential output seals are available online through most automotive parts retailers, such as AutoZone, NAPA Auto Parts, and Advance Auto Parts, or sites like Amazon and RockAuto. Most stores that sell automotive parts will also sell differential output seals. However, check with your vehicle’s owner’s manual to ensure you’re buying a seal compatible with your vehicle's make and model.
Where can I get my differential output seal replaced?
Changing your differential output seal is a tough job that’s not recommended at home, but finding the right auto repair shop to do the job can be tricky—especially if you don’t have a go-to mechanic in your area. Luckily, Jerry's

How will a mechanic replace my differential output seal?
Again, do not try to replace a differential output seal on your own. This is a service that a certified mechanic should complete.
Here’s what they’ll do:
- Verify that the differential output seal needs to be replaced
- Lift the vehicle onto jack stands
- Remove the CV axle and defective differential output seal using a seal removal tool
- Install the new seal, then reinstall the CV axle
- Refill the differential and test for oil leaks
- Remove the vehicle from the jack stands
- Test the vehicle for proper operation of the differential output seal
What happens if I don’t replace my differential output seal?
The differential output seal is important to prevent fluid from leaking out of the differential and causing damage to the differential and your car. When the differential seal cracks, becomes porous and isn’t replaced, the differential won’t be properly lubricated, so the bearings and gears can overheat. If these start overheating, it can lead to extensive damage to the differential that may render your vehicle inoperable until your differential is repaired or replaced.
What is a differential output seal replacement?
Differential output seals are the seals found at the output shafts of a car’s differential. They generally seal the axle shafts against the differential and prevent fluid from leaking out of the differential as the car is running.
If your differential output seal allows fluid to leak onto the differential, you’ll need to have a replacement as soon as possible.
While differential seals are simple, they are important to keeping your car running. Differential seal failures cause a lack of lubrication to your car’s internal components, leading to gears and bearings overheating and seizing.
You cannot check the fluid level of a differential with a dipstick—so if there is a leak, you will not know how much (or how little) is left. Taking your car to a mechanic is the best way to diagnose problems and have them fixed.
How do I know if my differential output seal needs replacing?
There are a couple of common signs that indicate you need a differential output seal replacement:
- There is fluid on the outside of the differential and axle
- Grinding noises coming from under the vehicle
- Burning gear oil smell
If your mechanic notices a small leak during normal maintenance, waiting on the repair is possible. If the differential leak is significant, it’s best to replace it immediately to avoid serious internal damage.
How often should you replace the differential seal output?
Like any other seal or gasket in your car, the differential output seal is prone to wear and tear from exposure to harsh elements, exposure to corrosive gear oil, and age. The chemicals that come into contact with the seal can dry it, causing it to crack and allowing oil to leak.
The differential fluid should be part of
routine car maintenance
. You’ll usually need to replace it after around 25,000 miles, so having your differential output seals inspected at the same time is a good idea. If a seal is found to be leaking during an inspection, they can replace it. Can I replace my differential output seal myself?
For drivers looking to
save money on car expenses
, changing the differential output seal yourself might cross your mind as a weekend DIY project—but it’s not recommended. The process can be slightly complex and time-consuming, so if you’re not super car-savvy, it’s recommended to leave it to a professional mechanic.FAQs
What causes a differential seal to leak?
A rear differential seal leak is common due to internal pressure when the axle vent is clogged. Sometimes, unclogging the axle vent can stop the seals from leaking, but they may also need to be replaced. Differential seals can also leak due to wear and tear and become dry over time.
How much does it cost to replace differential output seals?
The average cost to replace differential output seals is $288. However, your exact cost may be more or less based on your vehicle’s make and model.
Is it bad to drive with a leaking differential output seal?
Driving with a leaking differential output seal isn’t recommended, but the extent of damage depends on how much oil is leaking. If the leak is small, it’s not likely to cause damage, but if there is a significant amount of fluid leaking, it can affect the lubrication of the bearings and gears, causing them to overheat. This can lead to extensive damage to the differential. If your output seals are leaking, replace them as soon as possible to avoid damage to your transmission.
